Technical and economic analysis on applying continuous extracting water of power plant boilers to desulfuration regions for heating

In view of the serious energy waste problem caused by the continuous extracting water discharged from power plant boilers, puts forward a heat recovery scheme using the extracting water to supply heat to desulfuration regions. Analyses the feasibility of the scheme from the aspects of heat quantity taken and water quality requirement. Gives the flow chart of the scheme and analyses its economic benefit. The results indicate that the scheme can solve the heat recovery problem and is technically feasible, energy-saving and economical, which can provide a reference to similar power plants.
