Project summary

  • Project goal

Research and development of scientific and technical bases of forming infrastructure of low power for high mountain regions of Kyrgyzstan on the base of complex use of local specific power sources.
  • Introduction and overview

At the present time land reforms are carried out in the Kyrgyz Republic, and all lands are passed into private hands. Having realized that the most reliable and tested way of forming of a tight rural economy lies under breeding and cultivation, rural inhabitants have begun farming. Therefore, the last times, tendency of people settlement in mountain and high mountain regions is encreasing by creating a large number of populated areas. Inhabitants of recreated mountain populated areas are developing sewage farms and hook lands of foothill and mountain areas. Development of mountain areas by people brings to ecological crush. People prepare firewood by destroying valuable trees of archa and nut species that leads to soil erosion and arising of various natural cataclysims (landslide, snowslip, destroying of pasture etc.). Rubbish appearing from plants and animals is increasing around populated areas.

Stationary lines of electropower have not reached many populated areas and that is why people live in hard conditions that is characterized by following reasons:

  • Unstable or lack of electrical supply;
  • Lack of qualitative fuel for common need;
  • Absence of technical system for the use of specific power resource.

Aformentioned problem remains very important and is one of the main factors in stable development of mountain areas not only in Kyrgyzstan, but also in other countries of Central Asia (Tadjikistan, Afghanistan, mountainous regions of China etc.).

To develope remote and mountain areas of the republic, to some extent, depends on power supply, work employment of the population, technical and economical opportunities to form small manifucture and condition of life.

Life support power system of mountain areas provides for:

  • Complex use of local fuel and specific power resources;
  • Binding together of all used power settings into single power system which will provide communal-general and manifactural consumption of concrete houses or agricultural system.

This project envisages to conduct applied research, development and demonstration of autonomous power supply technology of mountain areas.


1. Applied research includes:

  • Monitoring of power supply condition in mountain areas;
  • Making up of a map of potencial of small power system in certain geographical areas;
  • Research of heat-transmitting effect of heat pipes in Stirling engine at complex with autonomous heat-and-power engineering settings;
  • Research of autonomous heat supply procces of methanoic anaerobious fermentation in biogas settings under the condition of absence of electrical power sources;
  • Research of high-velocity and low-velocity combustion of ecologically pure briquetted fuel from local ill-conditioned raw materials.

2. Development of technology provides for:
  • Use of heat-transmitting effect of heat pipes in Stirling engine at complex with autonomous heat-and-power engineering settings;
  • Autonomous heat supply procces of methanoic anaerobious fermentation in biogas settings in the condition of absence of electrical power sources;
  • Use of high-velocity and low-velocity combustion of ecologically pure briquetted fuel from local ill-conditioned raw materials for producing heat power.

3. The demonstration of the following technology is planned:
  • Heating and boiling, electrogenerating settings of everyday life;
  • Common electrogenerating apparatus with furnace device;
  • Bioenergetical setting with autonomous heat-and-power supply at the expense of solar collector and Stirling engine;
  • Portable and long combustion stove for heating dwellings and greenhouses.

More than a half of the project participants are weapon scientists from the Kyrgyz Republic and other CIS countries. They are involved in the project because they have certain scientific and technical beginnings on the concerned issue and able to accomplish the task, also achieve the aim of the project in concert.
  • Project tasks
  • 1. Conducting of monitoring of condition of power supply in mountain areas and make up a map of potential opportunities of using small power for certain geographical areas of the republic.

    2. Analyse of heat-and-power settings on the base of Stirling engine by using heat-transmitted effect of heat pipes.

    • Reaserch of heat-transmitted effect of heat pipes in Stirling engine;
    • Development of technology of retaining heating and electrical power by using heat and electrogenerated agregate for common need;
    • Making of heating-and-boiling and electrogenerated setting of common use.

    3. Conducting of bioenergetical setting with autonomous heat-and-power-supply under condition of absence of stationary source of electrical power.
    • Research of effectivness of different solar collector use, heat pipe and Stirling engine for providing necessary temperature rate at the reactor of biogas setting;
    • Development of bioenergetical setting with autonomous heat-and-power supply of reactor at the expence of solar collectors, heat pipe and Stirling engine;
    • Making of bioenergetical setting with autonomous heat-and-power supply of reactor at the expence of solar collectors, heat pipe and Stirling engine.

    4. Production of briquetted fuel from local organic raw materials:
    • Reseach of the mixture of fuel;
    • Development of the technology of briquetted fuel production from local organic raw materials;
    • Development of device for guided ecological pure incineration of briquetted fuel from local organic raw materials;

    5. Organization of demonstrational center of autonomous power system that works at specific sources of power for remote and mountain areas.

Above enumerated tasks are complex and the accomplishment takes many-sided character. But a positive result of the suggested work is extremely pressing, especially for the Kyrgyz Republic and other countries of Central Asia (Tadjikistan, Afghanistan, mountainous regions of Cina etc.) where stable development in mountain regions is directly connected with development of power infrastructure.
  • Expected results.

As a result of the project research, the following solution to the tasks are expected:
  • Inhabitants of mountain regions of Kyrgyzstan are provided with minimum comfort and gain opportunity to information access via television, broadcasting programs and INTERNET;
  • Protection of nut and archa forests of Kyrgyzstan from chopping down for firewood;
  • Preservation of ecological ballance of nature that decrease a risk natural catasrophe (landslide, snowlip, destroying of pature etc.);
  • In the connection of waste products use of plant and animal origin by way of raw materials for fuel, and environment in these regions will be improved;
  • Inhabitants of foothill and mountain regions obtain social and economical stableness during hard period in the country.
