Description

多重联合循环动力装置Multiple combined cycle power plant 技术领域：Technical field:
本发明属于能源与动力技术领域。The invention belongs to the field of energy and power technology.
背景技术：Background technique:
冷需求、热需求和动力需求，为人类生活与生产当中所常见。在动力需求技术领域，利用热能转换为机械能是获得和提供动力的重要方式。对于以汽柴油和天然气为代表的优质燃料，应该采用热效率高的直燃型燃气-蒸汽联合循环；对于非优质燃料和核燃料，采用间接式燃气-蒸汽联合循环时热效率也比较理想；尽管如此，它们实现的热效率依然不够完美，其根本原因在于——对每一种基本的热功转换技术而言，其自身都有各自固有的优缺点；同时，这些动力装置往往负荷很大，提高其热效率意义重大。Cold demand, heat demand and power demand are common in human life and production. In the field of power demand technology, the conversion of thermal energy into mechanical energy is an important way to obtain and provide power. For high-quality fuels represented by gasoline, diesel and natural gas, high-efficiency direct-fired gas-steam combined cycle should be used; for non-quality fuels and nuclear fuels, thermal efficiency is also ideal when using indirect gas-steam combined cycle; The thermal efficiency they achieve is still not perfect. The fundamental reason is that – for each basic thermal power conversion technology, it has its own inherent advantages and disadvantages; at the same time, these power units tend to be heavily loaded and improve their thermal efficiency. crucial.
就低温排放环节来看，蒸汽动力循环的优势最佳，但其获取变温热源热负荷时的传热环节温差损失大；就高温热负荷的获取环节而言，燃气轮机循环的优势独特，但其热排放环节温差损失大；因此，提高两种类型的燃气-蒸汽联合循环热效率的着眼点在于减少蒸汽动力循环的温差损失。为此，本发明提出了保留蒸汽动力循环优势，克服蒸汽动力循环不足，热效率高于传统燃气-蒸汽联合循环的多重联合循环动力装置。In terms of low-temperature discharge, the advantage of steam power cycle is the best, but the temperature difference of the heat transfer link when the heat load of the variable temperature heat source is obtained is large; the advantage of gas turbine cycle is unique in the acquisition of high-temperature heat load, but The heat loss of the heat discharge link is large; therefore, the improvement of the heat efficiency of the two types of gas-steam combined cycle is to reduce the temperature difference loss of the steam power cycle. To this end, the present invention proposes a multiple combined cycle power plant that retains the advantages of steam power cycle, overcomes the shortage of steam power cycle, and has higher thermal efficiency than the conventional gas-steam combined cycle.
