由于受到天然气供应的影响，天然气发电尚处于初始阶段。真正大面积的天然气发电作为分布能源站还要假以时日。现在的小规模天然气发电主要是在油田、气田以及机场、酒店、医院等。可以预计，随着天然气供应的愈加充足、供应范围的不断扩大，近几年天然气发电将会得到一个飞速的发展。燃气发电机组也借助社会能源需求的发展而发展，不同的动力机械存在什么差别呢？

Due to the impact of natural gas supply, natural gas power generation is still in its initial stage. It will take time for large-scale natural gas power generation to become a distributed energy station. The current small-scale natural gas power generation is mainly in oil fields, gas fields, as well as airports, hotels, hospitals, etc. It can be expected that with the increasing supply of natural gas and the continuous expansion of the supply range, natural gas power generation will experience rapid development in recent years. Gas generator sets have also developed with the help of social energy demand. What are the differences between different power machinery?

内燃机发电和蒸汽轮机、燃气轮机区别：发电装置分两块：发电部分和动力部分，一般发电部分都差不多，都是线圈切割磁感线，切割运动都是旋转运动，而动力部分就有区别了，这就是你要问的根本区别。

The difference between internal combustion engine power generation and steam turbine/gas turbine: The power generation device is divided into two parts: the power generation part and the power generation part. Generally, the power generation part is similar, with coils cutting magnetic induction lines and cutting motion being rotational motion, while the power generation part is different. This is the fundamental difference you need to ask.

1、燃气轮机：压气机(即压缩机)连续地从大气中吸入空气并将其压缩；压缩后的空气进入燃烧室，与喷入的燃料混合后燃烧，成为高温燃气，随即流入燃气涡轮中膨胀做功，推动涡轮叶轮带着压气机叶轮一起旋转；加热后的高温燃气的做功能力显着提高，因而燃气涡轮在带动压气机的同时，尚有余功作为燃气轮机的输出机械功。燃气轮机由静止起动时，需用起动机带着旋转，待加速到能独立运行后，起动机才脱开。

1. Gas turbine: The compressor continuously draws in air from the atmosphere and compresses it; The compressed air enters the combustion chamber, mixes with the injected fuel, and burns to become high-temperature gas, which then flows into the gas turbine to expand and do work, pushing the turbine impeller to rotate together with the compressor impeller; The work capacity of the heated high-temperature gas is significantly improved, so the gas turbine not only drives the compressor, but also has surplus work as the output mechanical work of the gas turbine. When a gas turbine is started from a stationary state, it needs to be driven by a starter motor to rotate. The starter motor will only disengage when it accelerates to independent operation.

2、内燃机发电:跟汽车等都是一样的，燃料在气缸内燃烧，燃气膨胀后推动活塞，活塞通过曲柄凸轮机构传给曲轴，曲轴做旋转运动，这就可以带动发电部分了。内燃机发电设备主要有柴油发电机组和燃气发电机组，燃气发电机组又分沼气发电机组、天然气发电机组、煤气发电机组、生物质气发电机组、瓦斯发电机组等等。

2. Internal combustion engine power generation: Similar to cars, fuel is burned in the cylinder, and the gas expands to push the piston. The piston is transmitted to the crankshaft through a crank cam mechanism, and the crankshaft rotates to drive the power generation part. Internal combustion engine power generation equipment mainly includes diesel generator sets and gas generator sets. Gas generator sets are further divided into biogas generator sets, natural gas generator sets, gas generator sets, biomass gas generator sets, gas generator sets, and so on.

3、蒸汽轮机：过热蒸汽进入到汽轮机，通过动静叶栅形成的喷嘴作用到转子上，即将压力能和热能转化为机械能，使转子旋转运动，同样可以带动发电部分了。

3. Steam turbine: Overheated steam enters the turbine and acts on the rotor through nozzles formed by the dynamic and static blades, converting pressure energy and heat energy into mechanical energy, causing the rotor to rotate and move, and also driving the power generation part.
