cogen
Combined Heat and Power (CHP), cogeneration, implies concurrent generation of electric and thermal energy in close proximity to the consumer. Ordinary electric power plants just discard as waste into the environment the heat produced in the electrical power generation process.

Cogeneration is the best way to attain higher efficiency of fuel consumption. Reduced amount of the required fuel and CO2 emissions per unit of produced energy is directly reflected in the reduced cost/price of the produced energy. In case of cogeneration the required amount of fuel is more than 1/3 lower than that required for separate electric and thermal energy production processes.

In case of cogeneration, fuel consumption total energy conversion efficiency generally makes 85-92%. Generated thermal power is used in production processes, domestic water heating and room heating or cooling. Absorption systems are used to produce cooling water. Mechanical energy converted into electrical energy can be used to operate electrically driven machinery (pumps, ventilation fans, compressors).

Out of the variety of cogeneration technologies we apply gas engine and gas and steam turbine based ones. The choice of cogeneration solutions for plants using local fuels is between steam turbine or ORC-technology (Organic Rankine'i Cycle) based ones.

Filter group companies has constructed 58 gas engine cogeneration plants with the total power output over 210 MW, 4 biofuel run cogeneration plants based on the fluidized bed boiler and steam turbine, 3 biofuel run cogeneration plants based on ORC-technology, and a 30MW gas turbine based cogeneration plant.
