Description

联合循环动力装置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；尽管如此，其实现的热效率依然不够完美，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；这些动力装置往往负荷很大，提高其热效率有重要意义。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, a direct-fired gas-steam combined cycle with high thermal efficiency should be used; however, the thermal efficiency achieved is still not perfect, the fundamental reason is that for each basic thermal work In terms of conversion technology, they all have their own inherent advantages and disadvantages; these power units are often heavily loaded, and it is important to improve their thermal efficiency.
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，内燃机循环的优势独特，但其循环冷却介质和燃气排放环节温差损失大。因此，提高优质燃料热效率的着眼点在于两点——减少蒸汽动力循环获取高温热负荷时的温差损失，将内燃机循环冷却介质带走的热负荷加以有效利用。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，将内燃机循环冷却热负荷加以有效利用，具有更高热效率的联合循环动力装置。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; in terms of the acquisition of high-temperature heat load, the advantage of the internal combustion engine cycle is unique, but The temperature difference between the circulating cooling medium and the gas discharge section is large. Therefore, the focus of improving the thermal efficiency of high-quality fuels lies in two points: reducing the temperature difference loss when the steam power cycle obtains the high-temperature heat load, and effectively utilizing the heat load taken away by the circulating cooling medium of the internal combustion engine. To this end, the present invention proposes a combined cycle power plant that has the advantage of retaining the steam power cycle, overcoming the insufficient steam power cycle, and effectively utilizing the circulating cooling heat load of the internal combustion engine.
