焦化气草莓视频黄色网站构成及发电原理在工程中各发电厂所使用的焦化气草莓视频黄色网站品牌不同，有国内设备、也有国外设备，其功率大小也不尽相同，但从整个瓦斯发电工艺流程来看是一致的，其系统都是由进气排气系统、点火系统、润滑系统、冷却系统、综合控制等系统构成。瓦斯电站布局示意图煤层气发电工程中都建有储气柜，保证燃机用气的稳定。

　　The composition and power generation principle of coking gas generator units vary among different brands of coking gas generator units used in various power plants in the project, including domestic and foreign equipment, and their power levels are also different. However, from the perspective of the entire gas power generation process, they are consistent, and their systems are composed of intake and exhaust systems, ignition systems, lubrication systems, cooling systems, comprehensive control systems, etc. Gas power station layout diagram: Gas storage tanks are built in coalbed methane power generation projects to ensure the stability of gas supply for gas turbines.

　　储气柜中的瓦斯气体经过瓦斯气预处理系统后，到达燃气机组进入燃机混合器中，同时空气经过空气滤芯后同时进入混合器。在燃机混合器内，燃机对空气和瓦斯气进行自动配比后形成混合气体，混合气体经过涡轮增压器后，再经过冷却器进行两级冷却，使气体温度稳定在一定范围内，通过不断调整节气阀，从而调整进气量，最后进入气缸内进行压缩、做功，从而使发动机驱动发电机进行发电。焦化气草莓视频黄色网站经做功排出的废气一般供给余热锅炉及其他换热设备或直接排入大气中。

　　The gas in the gas storage tank passes through the gas pre-treatment system and enters the gas turbine mixer. At the same time, the air passes through the air filter and enters the mixer. In the gas turbine mixer, the gas turbine automatically proportions air and gas to form a mixed gas. After passing through the turbocharger, the mixed gas is cooled in two stages by the cooler to stabilize the gas temperature within a certain range. By continuously adjusting the throttle valve, the intake air volume is adjusted, and finally it enters the cylinder for compression and work, so that the engine drives the generator to generate electricity. The exhaust gas discharged from the coking gas generator unit through work is generally supplied to waste heat boilers and other heat exchange equipment or directly discharged into the atmosphere.

　　The electrical protection of coking gas generator units generally includes overload, high frequency and low frequency, differential, grounding, excitation faults, etc., and the protection configuration varies among different manufacturers. During the experiment, refer to the technical documents of the gas turbine electrical protection device, check the contents of the fixed value sheet item by item, and set the CT ratio, PT ratio, current and voltage values, and various protection parameters on each side of the generator in the protection module. During debugging, use a relay protection tester to conduct corresponding simulated fault tests on the protection module to ensure reliable operation of the protection. Check the operation of the indicator lights on each plugin panel and the output of the outlet relay. Use a multimeter to check whether all the tripping outlet contacts of the protection are operating correctly at the terminals. Check the interlocking operation of external contacts with interlocking connections. Generally, it is important to focus on checking the interlocking actions of the high-voltage switch at the outlet of the generator after the protection action, the input and exhaust valves of the gas pre-treatment system, and the boiler system in the factory area. Verify the accuracy and reliability of the logical actions of each system.
