Iran plans to expand combined heat and power plants
Azerbaijan, Baku, Aug.6/ Trend F.Milad/
Iranian Energy Ministry has developed a plan to promote use of combined heat and power plants (CHP).
Energy Minister Majid Namjou said that the administration pursues the policy of promoting the use of renewable sources of energy, Mehr News Agency reported.
In July 2010, the IRINN reported that Iran's first privately owned combined heat and power plant officially came on stream in Tehran.
The plant's production capacity was 7.8 MW and its efficiency was 73 percent.
The average efficiency of the countries' plants is about 38 percent.
Cogeneration is the use of a heat engine or a power station to simultaneously generate both electricity and useful heat. It is one of the most common forms of energy recycling.
Conventional power plants emit the heat created as a by-product of electricity generation into the natural environment through cooling towers, flue gas, or by other means.
By contrast CHP captures the by-product heat for domestic or industrial heating purposes, either very close to the plant, or as hot water for district heating with temperatures ranging from approximately 80 to 130 °C. This is also called Combined Heat and Power District Heating or CHPDH. Small CHP plants are an example of decentralized energy.
