低沸点工质在余热利用中的应用分析.

Aiming at the large amount of lost of waste heat due to flue gas emission in thermal power plant, this paper expounds the selection basis and utilization characteristics of low boiling point working medium, proposes to generate by the recovered flue gas waste heat through low boiling point working medium, determines the relevant parameters of system through calculation, and analyzes the economy, energy saving capability and environmental protection benefit of the low boiling point working medium power system. The result of analysis shows that generating by low boiling point working medium can not long take the advantage of flue gas waste heat, but effectively save coal and enhance boiler thermal efficiency as well.
