摘要
从热经济性角度提出提高热电厂效率的几项技术和措施:通过凝汽器补充软化水,将外供蒸汽过热度降低;使用喷射式混合加热器回收热力除氧器排汽,作为生水加热器;利用压力匹配器代替减压减温器;用两相流加热器代替面式高压加热器等。
Proposed techniques and strategies from the view of thermo-economical performance for improving the efficiency of power plants.Include to lower the degree of superheat of output steam using soften make-up water from the condenser,to recover exhaust steam from thermal deoxygenator with jetting-type heater for raw-water heating,to replace conventional temperature and pressure reducer with jettingtype pressure-matcher,to replace surface-type high-pressure heaters with two-phase flow heaters,etc.
