Abstract

Abstract:

Lignite boiler preheater exhaust temperature above 161℃ is not energy efficient. Based on the energy grade gradient utilization principle and methodology of systems integration, system of tail flue gas waste heat integrated gradient utilization was designed and applied. Compared with traditional arrangement, the advantage of gradient utilization technology is significant.

Key words:

energy gradient utilization, flue gas waste heat, low temperature economizer, energy saving
