Description

燃气和蒸汽轮机系统 技术领域  Gas and steam turbine systems
本发明涉及能源电力技术， 尤其是涉及一种燃气和蒸汽轮机系统。 背景技术  This invention relates to energy and power technologies, and more particularly to a gas and steam turbine system. Background technique
燃气轮机是以连续流动的气体为工质带动涡轮高速旋转，将燃料的化 学能转换为动能的内燃式动力机械， 是一种旋转叶轮式热力发动机。  The gas turbine is a rotary impeller type heat engine that uses a continuously flowing gas as a working medium to drive the turbine to rotate at a high speed and convert the chemical energy of the fuel into kinetic energy.
通常， 燃气轮机包括压气机、 燃烧器、 燃烧室和涡轮机， 压气机将空 气压缩为高压气体， 高压气体在燃烧器内与燃料混合形成油气混合气， 经 点火装置点火后燃烧， 燃料燃烧生成的高温高压气体带动涡轮机旋转， 涡 轮机旋转驱动发电机组发电。  Generally, a gas turbine includes a compressor, a combustor, a combustion chamber, and a turbine. The compressor compresses the air into a high-pressure gas, and the high-pressure gas mixes with the fuel in the combustor to form an oil-air mixture, and is ignited by the ignition device to burn, and the high temperature generated by the combustion of the fuel The high pressure gas drives the turbine to rotate, and the turbine rotates to drive the generator set to generate electricity.
燃气轮机在工作过程中， 燃烧室内的燃料燃烧产生非常高的热量，因 此必须对燃烧室实施冷却， 以防止燃烧室因高温而导致损坏。  During combustion of a gas turbine, the combustion of the fuel in the combustion chamber produces very high heat, so the combustion chamber must be cooled to prevent damage to the combustion chamber due to high temperatures.
现有燃烧室冷却方法是风冷， 其具体方法是， 压气机泵出的高压气体 一部分用于与燃料混合燃烧， 一部分用于吹向燃烧室， 带走燃烧室的部分 热量， 实现对燃烧室的冷却。 在实际应用中， 压气机泵出的高压气体中， 有 25%-4 0%与燃料混合形成油气混合气并燃烧， 有 60%-75%的高压气体从 燃烧室的外壁间流过， 对燃烧室的外壁进行冷却， 然后进入燃烧室与高 温高压燃气掺混， 使燃气温度降低， 达到涡轮机工作要求的 65 (TC - 1 000 The existing combustion chamber cooling method is air cooling, and the specific method is that a part of the high pressure gas pumped by the compressor is used for mixing combustion with the fuel, and a part is used for blowing to the combustion chamber, taking away part of the heat of the combustion chamber to realize the combustion chamber. Cooling. In practical applications, 25%-4% of the high-pressure gas pumped by the compressor mixes with the fuel to form an oil-air mixture and burns, and 60%-75% of the high-pressure gas flows between the outer walls of the combustion chamber. The outer wall of the combustion chamber is cooled, and then enters the combustion chamber to be mixed with high-temperature and high-pressure gas to reduce the temperature of the gas to 65 (TC - 1 000).
°c。 °c.
可以看出， 现有技术中， 通过压气机泵出的 60%-75%高压气体冷却燃 烧室和降低燃烧室内的烟气的温度， 因而需要较大的能量用于冷却燃烧室 和降低燃烧室内的烟气的温度， 浪费能源。  It can be seen that in the prior art, 60%-75% of the high pressure gas pumped by the compressor cools the combustion chamber and lowers the temperature of the flue gas in the combustion chamber, thus requiring more energy for cooling the combustion chamber and lowering the combustion chamber. The temperature of the smoke, wasting energy.
此外， 由于空气的比热较小， 采用风冷的方式冷却燃烧室的冷却效果 较差， 容易造成燃烧室的损坏。 另夕卜， 从涡轮机排出的烟气中的热量没有充分的利用， 且大部分烟气 排放到空气中， 造成能源的浪费和环境的污染。 发明内容 In addition, since the specific heat of the air is small, the cooling effect of cooling the combustion chamber by air cooling is poor, and the combustion chamber is easily damaged. In addition, the heat in the flue gas discharged from the turbine is not fully utilized, and most of the flue gas is discharged into the air, resulting in waste of energy and environmental pollution.
