Application of PTFE heat exchanger in Low Temperature Waste Heat of Big Coal-fired Power Plants

摘要

With the rapid development of the national economy, the use of low-temperature heat in thermal power plant boiler can not be ignored. Although low temperature economizer is widely used in low-temperature waste heat recovery of thermal power plant boiler, the problems of corrosion and fouling are very significant. New type PTFE heat exchanger filled with high thermal conductivity properties can replace the existing metal heat exchanger, fundamentally solve the problems of corrosion and fouling, meet the future development of the thermal power plant, and realize the energy recycling to maximize the benefit of energy.
