Description
Technical field
The present invention relates to a kind of method that power provides, belong to heat power technical field.
Background technology
General steam class PTO (steam engine, steam turbine), the thermal efficiency of steam expansion acting is subject to the impact of initial temperature, first pressing, exhaust temperature, exhaust steam pressure.
When initial temperature is constant, the temperature difference is higher, and efficiency is higher.First pressing is higher, efficiency is higher.When initial temperature is constant, exhaust temperature is lower, and efficiency is higher; Exhaust steam pressure is lower, and efficiency is higher.
Because Steam Power Equipment expands to do work, can produce general vapour, general vapour need be condensed into worker quality liquid and just can make to loop down.So the exhaust temperature of Steam Power Equipment generally need be higher than environment temperature.In addition, improve the initial temperature of Steam Power Equipment, must improve its pressure, pressure improves higher to the withstand voltage designing requirement of steam power machinery, and the space of improving at present steam initial temperature is also less.So the space that the efficiency of water vapour power set further promotes is very little.
Secondly, because low-grade heat source cannot provide higher initial temperature, exhaust temperature must adopt the steam power machinery efficiency of low-grade heat source low higher than environment temperature again, and practical value is low.
