式燃焼装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a combustor that combusts a gas fuel from a fuel supply path with compressed air from a compressor, and a boiler that uses hot air from the combustor as a heat source. And a gas turbine driven by hot air from the combustor in conjunction with the compressor, and a reduction passage for returning exhaust gas from the downstream side of the gas turbine to the suction side of the compressor.
従来、低NOx化のために燃焼器に排ガスを還元供給す
るに、例えば200℃程度の高温の排ガスをそのままコン
プレッサーに送るように構成していた。Conventionally, in order to reduce NO x , exhaust gas is reduced and supplied to the combustor, and for example, high-temperature exhaust gas of about 200 ° C. is directly sent to the compressor.
しかし、低NOx化に十分な量の高温排ガスを混合する
と、コンプレッサーに吸込される空気の温度がかなり上
昇し、コンプレッサーに供給される加圧空気の質量流量
がかなり減少して、燃焼器の燃焼能力が低下する。However, when mixing a sufficient amount of hot exhaust gases to the low NO x reduction, increased considerably the temperature of the air to be inlet to the compressor, to decrease the mass flow rate of pressurized air supplied to the compressor rather, combustor Burning capacity is reduced.
ちなみに、コンプレッサーの吸入空気が45℃に上昇す
ると25℃の場合に比して10％程度コンプレッサーの加圧
空気供給能力が低下し、一層の改良の余地があった。By the way, when the intake air of the compressor rises to 45 ° C, the compressed air supply capacity of the compressor is reduced by about 10% compared to the case of 25 ° C, leaving room for further improvement.
本考案の目的は、排ガス循環による低NOx化を十分に
図りながら、燃焼能力を十分に大きくできるようにする
点である。An object of the present invention is to make it possible to sufficiently increase combustion capacity while sufficiently reducing NO x by circulating exhaust gas.

せることができる。しかも、排ガス冷却器の冷却排水路
をボイラに給水のために接続して、排ガスの排熱を回収
した水をボイラに給水するので、排熱回収による熱効率
を向上することができる。That is, by mixing the low temperature and exhaust gas in the exhaust gas cooler, while achieving a sufficiently low NO x by the exhaust gas mixture, it can be sufficiently low compressor intake air temperature, pressurized combustion supplied to the combustor from the compressor The mass flow rate of the working air can be sufficiently increased to burn the combustor. Moreover, since the cooling drainage channel of the exhaust gas cooler is connected to the boiler for water supply and the water from which exhaust heat of the exhaust gas has been recovered is supplied to the boiler, thermal efficiency due to recovery of exhaust heat can be improved.
その結果、NOx濃度が十分に低くて大気汚染防止に有
効であると共に、高負荷燃焼が可能で、しかも、排熱回
収により熱効率を向上できる、一段と性能の優れたター
ボ式燃焼装置を提供できるようになった。As a result, it is possible to provide a turbo combustion device that has a sufficiently low NO x concentration, is effective in preventing air pollution, can perform high-load combustion, and can improve thermal efficiency by recovering exhaust heat, and that has even better performance. It became so.
