Environmental Assessment for concentrated heat source types of domestic hot water supply

摘要

Analysis the impact on atmospheric environment that the running of concentrated heat source takes in domestic hot water supply in northern China.Carry on environmental impact assessment to six concentrated heat source programs of hot water supply system using the method of fuzzy comprehensive evaluation.It indicates that the pollution of conventional coal-fired heat source in hot water supply system on atmospheric environment is the most serious and the pollution of gas-fired heat source in hot water supply system on atmospheric environment is the smallest.Coal-based heat source must be set to the efficient dust removal,cleaning devices,in order to reduce the pollution to the environment and conditionally it should maximize the use of gas,heat pump and other cleaner energy.
