Topping Cycle - an overview | ScienceDirect Topics
The binary power plant can reach very high efficiency because higher temperatures are possible at the topping cycle when the vapor pressure in the boiler is not high. The most attractive of the binary cycles appears to be the steam-mercury power plant which has been proposed in the past for both stationary power generation and astronautic applications.

Numerical Model of Thermoelectric Topping Cycle of Coal Fired Power Plant …
2014/2/26 · This study investigates the potential placement of TE on water tube wall inside a boiler at a coal fired power plant. Three dimensional (3D) numerical model of a simplified TE module is developed and hot gas temperature and steam temperature from the boiler are used as boundary conditions at the hot side and cold side of the TE.

Combined Heat and Power Technology Fact Sheet Series
Abstract. An existing power plant can be repowered at a modest investment cost through a topping turbine installation. Essentially, this consists of replacing the existing old, low pressure boilers with new, high pressure boilers and adding a new, high pressure, non-condensing turbine (topping turbine) . The high pressure steam generated in the
