Combined Heat and Power System
Description:
Combined heat and power (CHP), also called cogeneration, is the simultaneous production of heat and electricity from one fuel source such as natural gas, biogas and waste heat. Combined heat and power system can efficiently utilize the waste heat from burning fossil fuels to generate electricity and useful heat. The key components of a CHP system include an internal combustion, reciprocating engine driving an electric generator.
Application:
Combined heat and power system is applicable to industrial manufactures, commercial and residential settings. The heat produced at the electric utility goes into the cooling water or up the smokestack along with pollutions. Thus two-third of the energy is wasted. While CHP system can recover nearly all of the heat it produces. This cogeneration system provides electricity and heat at a combined efficiency approaching 90%. It is a great improvement over the combination of the 35% efficient electric utility and a conventional heating boiler with a 65% seasonal efficiency.
Features of Combined Heat and Power System:
1.CHP system is designed to put the waste heat into good use.
2.Cogeneration requires less fuel to produce a given amount of electricity and usable heat.
3.CHP system can reduce air pollution and greenhouse gas emissions.
4.Combined heat and power system with high efficiency provides environmental and economic benefits.
5.Cogeneration reduces the demand on the utility grid, but raise energy efficiency.
