Abstract:

Abstract:The conventional calculation method of coal consumption for heat supply of cogeneration unit was introduced. Using the heat balance block diagram, the commonused heat for heat supply and power generation was found, which is the heat consumption in combined heat and power generation and does not be shared in the heat supply ratio calculation formula. The amendment of heat supply ratio calculation formula was proposed, which can be used as reference for calculation of coal consumption for heat supply.

Key words: Key words:combined heat and power generation (cogeneration), heat supply ratio, share, coal consumption for heat supply, commonused heat for heat supply and power generation
