| 摘 要： | 汽轮机热力系统中的加热器的运行情况对机组经济性有较大的影响,采用等效焓降法定量分析ANSALD TCDF-33．5型机组加热器端差对机组经济性的影响。结果表明,如果加热器端差从运行的实际值减少至设计值,机组经济性明显提高。这项工作对指导回热系统运行及研究机组经济性具有重要意义。

| Abstract: | Heater terminal temperature difference of steam turbine thermal system can cause biggish infections on unit eco- nomic.This paper took the ANSALD TCDF-33.5 model unit as an example,equivalent enthalpy drop was adopted for an- alyzing heater terminal temperature difference effect on unit's economic.The results indicated:if heater terminal tempera- ture difference decrease to designed value,unit economic could improved in evidence.This work is identified as being criti- cal significance to direct operation of heat recovery system and research unit economic. |
