燃气透平与别的原动机(电动机、内燃机、蒸汽透平)不同,有以下优点:1.能使用各种燃料,包括热值只有1100千卡/标米~3的工厂废气,重质的燃料油和丙烷等,而且即使燃料的热值变化大,它的出力的变化也较小。2.在运转过程中,可以变化燃料种类,由瓦斯切换为油,或由油切换成瓦斯。3.从透平排出来的烟气中,氧浓度还十分高,这部分剩余氧可以用来作为燃烧所需的氧元素的来源,加之排烟温度颇高,其可燃性是不容置疑的。人们早己认识到“燃气透平—加热炉”联合系统的长处。要最大限度地从“能”的
Gas turbines, unlike other prime movers (motors, internal combustion engines, and steam turbines), have the following advantages: 1. They can use a variety of fuels, including factory exhaust with a calorific value of only 1100 kcal / Fuel oil, propane and the like, and its output variation is small even if the fuel has a large change in calorific value. 2. In operation, you can change the type of fuel, from gas to oil, or from oil to gas. 3. In the flue gas discharged from the turbine, the oxygen concentration is still very high. This part of the remaining oxygen can be used as a source of oxygen for combustion. In addition, the flue gas temperature is high, and its flammability is beyond doubt. It has long been recognized the strengths of the “gas turbine - furnace” combined system. To maximize the “can”
