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 power generation device is divided into two parts: the power generation part and the power generation part. Generally, the power generation part is similar, both of which are coil cutting magnetic induction lines, and the cutting motion is rotary motion. However, the power generation part is different, which is the fundamental difference you need to ask.

1、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。

1. Internal combustion engine power generation: Similar to cars and other vehicles, fuel is burned in the cylinder, and the gas expands to push the piston. The piston is transmitted to the crankshaft through the crank cam mechanism, which 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.

2、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。

2. Steam turbine: Superheated steam enters the turbine and acts on the rotor through nozzles formed by the moving and stationary blades, converting pressure and heat energy into mechanical energy, causing the rotor to rotate and move, which can also drive the power generation part.

3.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著提高，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

3. Gas turbine: The compressor continuously sucks 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. It then flows into the gas turbine to expand and do work, pushing the turbine impeller to rotate together with the compressor impeller; The power output of the high-temperature gas after heating 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 starts from a stationary state, it needs to be driven by a starter motor to rotate. The starter motor only disengages after accelerating to independent operation
