Small Scale Plants (CHP)


Nowadays, the hot topic of energy and optimizing energy consumption is one of the most important ones in engineering science. Considering the energy high value and the decreasing trend of fossil fuel, the public attention is shifted toward optimizing and controlling energy consumption via high-tech systems which have high efficiency. Researches in this area have long been started in many industrial countries with its primary steps being taken in developing countries. Due to the changes in the structure of power generation and privatization and the importance of environmental issues, power generation technology has been lured into diffuse generation. One the most important approaches in this regard is the exploit micro-turbine generators.  High efficiency and low mass, in addition to causing less pollution for the environment, have made the generator be in the center of attention. This kind of generator can be used in order to remove power consumption peaks in the regions where it is not feasible to construct big power plants and where the independent use of the grid is intended.

Combined of heat and power (CHP) technology includes using an energy source for the purpose of generating two common types of energy, electricity and heat, in the consumer area. By exploiting this approach, the electricity and heat loss is substantially decreased. During the last three decades with the rise in the importance of finding an alternative for fossil fuel, in attempts for boosting energy efficiency and with the upsurge in the importance of decreasing greenhouse gases, the tendency to use new technologies such as combined heat and power (CHP) has been rocketed. One area to use this technology is industry. Currently, due to the high and rather continuous demand for the combined heat and energy, combine heat and energy production is extensively developed throughout the world. Exploiting CHP, in addition to improving technical conditions and decreasing energy consumption, is economically attractive. However, constructing the combined generation units cannot be sensible for all the industries and in all consumption patterns. That is, making use of this approach needs more investigations and calculations. According to the researches done by different countries and their findings related to the combined production in industry, the industries that are considered as good options to adopt this approach include food, textiles, non-metals (cement, glass, ceramic), metals, wood and paper industries.

Need for electricity in our society is increasing about 7% annually, because of high consumption of energy in household chores, industries and agriculture. In electricity circle, three main activities are:

  1. energy production unit which is responsible for generating energy for the power plants;
  2. transfer unit and ultra-distribution which is responsible for the energy transfer from generation centers (power plants) to the consumption centers (distribution grid);
  3. distribution unit which is responsible for distributing energy to houses, commercial units, and agricultural areas.

In order to supply energy for the region that consumes energy, electricity must be produced in power plants, distributed via transfer and ultra-distributing lines, and finally, be delivered to the consumers. However, if we produce part of demanded electricity in the same region that the energy is consumed, a considerable amount of energy is saved in all the three units of production, transfer and ultra-distribution.

CHP benefits:

  1. theoretically saving at least 10% in energy consumption. However, more energy saving occurs practically;
  2. saving costs to the extent of about 15 to 40% than the other generators. This is because of the combined production of power and heat by the boilers in the region that consumes energy;
  3. at least 10% decreasing CO2 because of the good quality of the produced natural gas in CHP in comparison to the other common energy generators;
  4. High final efficiency up to 80% or more, depending on the region of energy consumption;
  5. more security in energy transfer both for the operator and consumer;
  6. secure and well-proved technology based on self-sufficiency;
  7. decreasing the energy costs, creating a competitive atmosphere in business and industry, decreasing fuel consumption and decreasing public services costs;
  8. Increasing security in energy transfer and less energy loss by using fuel more efficiently- whether the fuel is renewable or fossil type;
  9. increasing flexibility and reliability in energy supply-both in local and national level
  10. being flexible and responsive to the heat production-heat energy (heating or cooling) in CHP generators can be easily saved and delivered based on the costumers’ demand;
  11. decreasing focused total demand for major fuels such as coal in large scales or gas in plants, and as a result, decreasing stress in power grid;
  12. governmental support and the plan of power guaranteed purchase and gas free delivery, in case of implementing CHP.

Tarh Gostar Pouyesh Company in technology, engineering, service, and economic energy production as well as clean fuels has bound more than 250 contracts in different areas of servicing, engineering, and business. Also, by acquiring construction permissions of CHP small scale power plant with 12 megawatt capacity and the execution of such plant, the company has gained valuable experience in permission acquisition and analysis of the right location for implementation. Also, it gained experiences about all the necessary technical and engineering activities to maintain and establish CHP generator system, consulting in regard with the supply of appropriate machines and equipping the generators with all the brands by the help of skilled and experienced staff. Now, Tarh Gstar Pouyesh Company with its 10 years of seamless and perfect experience in technical and engineering in clean fuels and human resources is ready to collaborate with all legal entities and real persons in all the stages from initial consults the to the CHP operationalizing.
