Abstract

Abstract:

Direct at the problem of only one turbine's waste heat can be recovered in typical double-units configuration power plant, the waste heat quantity of the wet cooling unit and the present technologies' ability to recover waste heat were analyzed quantitatively. A heat supply system that absorption heat pumps in series low pressure cylinder with bare-shaft to recovery waste heat from circulating water was presented. And the system to recover waste heat of steam turbine driving feed water pump was also proposed. With the system, all the two units' waste heat could be recovered to supply district heat for the typical double-units configuration power plant.

Key words: heat and power cogeneration, steam turbine, waste heat supply, waste heat of circulating water
