Description
Technical field
The present invention relates to a kind of exhaust heat stepped utilization formula device and the working method of marine main engine, especially a kind of Ship Waste Heats
Light four combined production device of cascade utilization formula cool and thermal power, belongs to energy project technical field.
Background technique
Currently, host waste heat is mainly recycled by the way of two-stage afterheat boiler in terms of marine main engine UTILIZATION OF VESIDUAL HEAT IN, then
Marine main engine waste heat is changed into electric energy by steam turbine, generator etc., meets ship power demand.With regard to two-stage afterheat boiler
For, host flue-gas temperature from 350 DEG C be reduced to 120 DEG C during, hiigh pressure stage waste heat boiler undertakes the transformation of main thermoelectricity
Work, and the usual efficiency of low-pressure stage waste heat boiler is lower, working efficiency has raising to be optimized.
