Analysis of cogeneration central heating
Cogeneration central heating has the advantage of energy saving, but the construction period is longer
Cogeneration central heating is a main way of urban central heating, the main purpose is to save energy, is a recognized energy saving and environmental protection technology. Compared with other district heating methods, cogeneration usually requires more investment and a longer construction cycle.
-- Cogeneration has become the main form of central heating in China
China has a variety of heating methods, mainly including cogeneration, regional boilers, distributed boilers, electric film, heat pump technology, etc., has gradually formed a heat supply situation based on cogeneration, supplemented by centralized boiler rooms and supplemented by other advanced and efficient ways. According to the statistics of the Ministry of Housing and Construction, in the total amount of urban central heating in 2021, cogeneration heating accounts for the main part, accounting for about 67% of the total central heating.
-- Hot water central heating is the main method of cogeneration central heating
The central heating methods of thermal power plants can be divided into steam heating and hot water heating. According to the data released by the Ministry of Housing and Urban-Rural Development, the main way of urban central heating in China's thermal power plants in 2021 is hot water central heating, the total heat supply reaches 2,030.57 million GW, accounting for 77% of the total heat supply of thermal power plants, and the steam central heating of thermal power plants reaches 601.9 million GW. It accounts for 23% of the total central heating of thermal power plants.
