摘要：In view of the drawbacks of the traditional scheme of recovering residual heat from slag cooler to condensate water system, this paper proposes a new scheme for the utilization of residual heat from slag cooler of circulating fluidized bed heating units. During heating period, a return water from heat network is drawn from the main return water pipeline of heat network as the cooling water source of slag cooler. The residual heat of slag cooler is directly used for heating, and the residual heat of slag cooler will be recovered to condensate water system in non-heating period, in order to realize the free switching between the two schemes, valves are installed in the pipeline. The energy-saving effects of the two schemes are analyzed, and the results show that the new scheme is more energy-saving.
