EHFE – technology application area

Picture 1 illustrates "the classical" concept of well-known steam power plants, the colors on the chart show the change in temperature of the working fluid. This scheme is a closed loop, where the working fluid consumption as a vapor is compensated by the working liquid supply from the feed pump. The pump, while pumping condensate, overcomes the operating pressure, over few 100 Atm. It is a great pressure, and to overcome this pressure, a sophisticated multi-circuit feed pumps (schemes) are often used. Most importantly, the power cost of rotation of these pumps is up to 20% and depends not only on the result of normal use and aging, or type of the feed pump, but also on the type of working fluid. For example, in recent years a low-boiling working fluid is widely used to implement the ORC (Organic Rankine Cycles), where the generation of 1 kW of power requires much more of the working fluid flow in comparison with "water" Rankine cycle, which dramatically increases the power costs of the feed pumps rotation.

EHFE - technology eliminates the necessity for a feed pump with a consumed capacity costs on their rotation, thus it creates conditions for heat transfer efficiency rise, and it is applicable in steam power plants especially while operating ORC - modes, as well as for the local power systems (private energy, private house, on the street, in block of flats, on the enterprise, etc.)

EHFE – technology application area

Picture 2 illustrates one of the Stirling engine's "classical" schemes. It is well known that the steam-engine working on the Stirling cycle with an external heat supply is much more environmentally friendly, compared to internal combustion engines. Moreover, Stirling engines have potential efficacy comparable only with the maximum efficiency of the Carnot cycle. In reality, we are struggling to achieve this efficiency due to a number of technological reasons, related to the thermal stability of structural materials, little heat transfer efficiency during a multiple (dozens of times per second) working fluid from relocation from "cold" to "hot" area of the engine, as well as due to hydraulic losses and the related difficulty of engine sealing while operating at high fluid working bodies (helium, hydrogen), etc.

EHFE - technology not only solves these problems, but also shows us in a new light the engines operating on the principle of the device cycles like the Stirling cycle. It became possible to approach the top of efficiency and environmental performance using the engine that meets the requirements of simplicity, reliability and competitive advantages.

Description of EHFE – technology

Picture 3 shows a schematic diagram of a steam plant with fragmentation (division), and the periodic sealing the working fluid in the chambers. This example illustrates one of the areas of application EHFE - technology and implements the principle of the working fluid pumpless circulation by temporary connection of cameras and difference between the vapor and liquid densities of the working fluid phases in them due to the dependence between boiling temperature and the pressure, according to the individual 'saturation lines" for different operating fluids. This simple and reliable technical solution makes it possible not only to implement the closed circuit pumpless steam power plant, but also to use fragmented (divided) in chambers working fluid to be heated by any heating medium due to implementation of a countercurrent heat exchanger scheme.

This decision is at the basic level is patented by our company, the patent search indicates the innovation of this development. We also cooperate with representatives of the Siberian Federal University (SFU), who are very interested in our work, and we are preparing for scientific survey, research and technological development (R & D). We have signed the contract with Technology Company, specializing in heating equipment (boilers) production. Its design department is now creating the original concept of the heat-electric generating installation of low and medium power running on natural gas or fuel pellet with a separate coolant circuit between the combustion products and the working fluid. A high-quality design task is to investigate precisely and create tools for the liquid phase replacement by the vapor phase when the working fluid flows from the "upper" to the "lower" chamber with simultaneous heat exchange through the wall of the steam pipe or directly, without the steam line between these phases. There are preliminary calculations describing this process made by employees of SFU.


Due to the rejection of the feed pump and usage of a piston converter, which does not require lubrication, the developed system is notable for its simplicity and high reliability. It is applicable in the local (private) energetics, as well as in the markets, incurring the deficit in such technologies and it has great prospects for global development.

Description of EHFE – technology

Picture 4 represents a schematic diagram of a steam installation showing another example of EHFE – technology. Just like in Scheme (Picture 3), the principle of pumpless working fluid circulating and its heating by intermittently fragmentation of the working fluid in the radial chambers is also implemented. There is no replacement of the working fluid during its heating between chambers. The working fluid is located in the same cell from the moment of filling in in the form of condensate until the vapor outlet. Filling and emptying of such chambers is managed by switching the working fluid's supply and discharge channels, and also the flow of the heating medium is switched with respect to the chambers warm up to comply the principle of countercurrent heat exchanger.
In the experimental setup, developed by our company, the switching of the heating medium flows as well as the supply or discharge of the working fluid are implemented by distributor. Moreover, a depleted working fluid (intracyclic recuperation) is used as the flow of the heating medium on that stand. In contrast to the circuit (Picture 3), irreversible losses, associated with the movement of the working fluid between the chambers, are completely absent in the diagram on Picture 4. The costs on the distributor rotation are very small and initially estimated not more than 1% of the generated power.
The company has done a big amount of work which is still in progress. An active patent work is in progress, and a stand has been created, where along with the scheme of intracyclic recovery, an "isothermal" reciprocating converter is used. It will be discussed in detail below.
A contract with technology partner – "Apeyron" has been signed to continue the work on that stand. We are preparing for R&D together with the scientists from SFU. A preliminary conclusion about the prospects of development is compiled; basic calculations, demonstrating the efficiency of the plant, using specific capacitance at about 37% of efficiency coefficient for an ideal cycle with pentane as the working fluid, and a maximum temperature of 240 degrees, are made. 240 degrees is far from the temperature limit, the materials of construction allow to increase the temperature in at least two time, which will significantly increase the value of efficiency coefficient and power density. An important feature of the scheme is the ability to work on supercritical parameters for working fluids with phase change and gaseous working bodies as there is no need to maintain the difference between vapor density and liquid phase's density of the working fluid.


The implementation of flow distribution in this manner is an important part of EHFE - technology and it is especially promising because it allows you to achieve maximum efficiency in the overall simplicity of the engine's design or steam power plant.

A Company's technology, which is optimally – compatible with EHFE - technology

Various cycles with internal recuperation optimally fit the described above schemes of steam power plants and engines with EHFE - technology for heating fragmented working body on the basis of the countercurrent heat exchanger. Effective internal cycle's recovery or recuperation, such as regenerative cycle of Stirling, allows to approach the maximum possible efficiency of heat engines. Working fluid regenerative cooling and heating processes are optimally correlated with isothermal compression and expansion processes in Sterling cycle. It is known, that the temperature preservation by supplying heat and especially its rise during the working fluid expansion, gives the largest value of the produced work in relation to the weight of the consumed working fluid. It makes a combination of the effective "isothermal" converter along with EHFE – technology very promising.
Pic. 5.1
Our company has developed a high-quality "isothermal" converter with an increased heating area. This technology is very valuable and the application for a patent has applied as well as the testing stand has been made. There is an agreement with the Siberian Federal University to conduct R&D with the preparation of numerical simulation software. Preliminary estimations show a dozen - times improved heat transfer performance, for working fluids with phase change and gaseous working media.

This converter allows to decrease a heater's temperature with specific capacitance value, comparable to the classical Stirling engines, which reduces the requirements for materials, reduces cost and increases the service life, etc. This converter allows the use "heavy" working body with low fluidity, thereby reducing the requirements for steam tightness and for the plant in general, etc.

This scheme of "isothermal" converter enables highly efficient compression of any working fluid, whether it is a converter as a part of an engine (cold cylinder Stirling engine) or a simple compressor.

An example of EHFE – technology in an engine with phase change of the working fluid

Picture 6 illustrates an idealized thermodynamic cycle in following coordinate representation: the pressure (P) and volume (V) for a steam power plant with applied EHFE - technology and adiabatic converter (turbine, the cylinder-piston group without heat supply).

This cycle, excluding the process 4-1, is similar to the well-known Rankine cycle. The difference of process 4-1 is that the increase in pressure up to the operating value at constant volume in case of the Rankine cycle is achieved by the supply pump, and in our case it is achieved by heating of the working fluid in the chamber with constant volume. All the other processes are similar: 1-2 - boiling / evaporation; 2-3 - adiabatic expansion of the working fluid in the converter; 3- 4 - condensation.


Pic. 7
Picture 7 illustrates an idealized thermodynamic cycle in following coordinate representation: the pressure (P) and volume (V) for a steam power plant with applied EHFE – technology and with additional technology, developed by our company - an "isothermal" converter (cylinder-piston group with a supply of heat). This cycle is unique, and just like in previous case, the process 5-1 is to rise the working fluid pressure at a constant volume of the chamber due to its heating. The process 1-2 – is the process of boiling and evaporation. Process 2-3 is an "isothermal" or approximate to it working fluid expansion. Process 3-4 – is a regenerative cooling of exhausted working fluid with heat transfer from this process to the process 5-1. Condensation process 4-5.

Calculations from employees of SFU were performed, using the Coolprop http://www.coolprop.org function (link). An example for pentane calculation are mentioned earlier. Calculations show up to 30% increase of the produced work in case of isothermal or "excess" isothermal expansion of the working fluid. It also shows up to 20% increase in the produced work due to the absence of the cost on the feed pumps rotation, especially in case of low-boiling working fluids for ORC plants.

An example of EHFE – technology implementation of the engine with the gaseous medium.

Picture 8 illustrates: A) the process of the working body expansion in the chamber 3 and above the piston space with simultaneous compression process in sub piston space and chamber №1.

In cycle's position 1- the piston is close to the heater and the above the piston space value is close to minimum, there is the opening of the inlet distributor channel.
In cycle's position 2 - the piston is in an intermediate position, the inlet closure occurs (this point is given as an example, it might be absent).
I cycle's position 3 - the piston is removed from the heater, the space value above the piston is close to the maximum; if there is no point 2 the inlet closure occurs.
I cycle's position 4-5 – the compression process takes place simultaneously with the expansion process.

Picture 8 illustrates: B) he working fluid recuperation processes in chamber №2 There is a simultaneous heating of the working gaseous medium in chamber №2 and cooling of the exhausted working gaseous medium.

In cycle's position 3 - the piston is distanced from the heater, the space value above the piston is close to the maximum, the discharge passage and compression channel are opening, and the recuperater heat exchanger in chamber №2 is connected via those channels
In cycle's position 4 - the piston is close to the heater and above the piston space value is close to the minimum, the working gaseous medium moved through the recuperate heat exchanger of chamber №2 from the above piston space to the below the piston space.
In cycle's position 5-1, the working gaseous medium heating process in chamber 2 takes place simultaneously with working gaseous medium cooling when it passes between the positions 3-4.

In the illustrated example, the cycle may approach the top of ideal efficiency of the Stirling and Carnot cycles. The cycle's feature is the simultaneous processes of expansion and contraction, and also in the regenerative processes of simultaneous heating and cooling. It became possible due to EHFE – technology, as the different fragments of the working fluid are involved, which allows to increase the efficiency of heat transfer, by increasing the number of chambers and their capacity.

Cooperation and Development
At the beginning our start-up was developing with an emphasis on a high-quality intellectual property - what we've been doing during last 4 years - is primarily a reflection and refinement of the principle of fragmentation and recuperation, and protection of intellectual property (2 key patent in 2014, 2015 and 2016)

So now we are considering two possible options:

The first way is to sell a full research and development (just because we appreciate the physical resources and we are interested in a lot of different projects which we are ready to develop. We only want to retain the right to use their patents and produce products based on them on the territory of Russia. )
The second way is to find a "Business Angel" to go together through additional expertise and authoritative conclusions, to detail further EHFE solutions, to create and describe concepts and technical solutions developing (e.g., electricity generator development), and to strengthen the patent umbrella and to develop the licensing

All this time we have been a non-public company, while we've been waiting for the results of patent search and examination, but the steps for further work are now required with the participation of the best world experts.

If you are interested, all you need to do is write to us (we would really appreciate if you describe the possible way of cooperation in details).
- You are always welcome to visit us in Novosibirsk, where we can introduce you to our technology

- We will also attend the exhibition Slush.org in Helsinki (30/11/2016 – 01/12/2016) and then the exhibition in Germany (approximately from the 10th of December). We are looking forward meeting you there in person.
We deeply hope you realize that at a present stage (until March 2017) we are ready to introduce the patents and all details only when we feel a good potential for cooperation and an opportunity to build mutually beneficial partnerships.

Our great desire for this development is to be embodied in millions of devices for the benefit of the environment and the world in the near future.
