The utility model provides a flue gas waste heat reclaimer for power station boilers. One end of an inlet tube of a heat exchanger is communicated with a pipeline between a gland heater and a lower-pressure heater, the other end of the inlet tube is communicated with a coil in the heat exchanger, the other end of the coil is connected with a deaerator through a return tube of the heat
In this paper, the design and operation of a compact Waste Heat Boiler developed as part of the main generator package for the DDH 280 Class Royal Canadian Nary (RCN) Destroyer. The Waste Heat Boiler operates in a controlled system that converts exhaust heat from the generating sets into steam that is used for hotel services onboard the vessel.
The invention discloses a boiler smoke waste heat utilization system. Smoke from a boiler (21) enters a chimney (27) to be discharged after passing through an air pre-heater (22), a smoke cooler (23), a desulfurization system (26) and a smoke heat exchanger (29) sequentially, smoke cooled by the smoke cooler (23) enters the secondary smoke heat exchanger (29) through the desulfurization system
