燃煤发电机组原理及操作技巧

燃煤发电机组,是将煤等化石燃料的化学能转化为电能的机械设备。 燃煤发电机组工作原理:是将煤燃烧产生的热能,通过发电动力装置(电厂锅炉汽轮机和发电机及其辅助装置等)转换成电能。燃煤发电历史较悠久,也是较为重要的一种。

Coal fired power generation units are mechanical equipment that converts the chemical energy of fossil fuels such as coal into electrical energy. The working principle of coal-fired power generation units is to convert the thermal energy generated by coal combustion into electrical energy through power generation devices (such as power plant boilers, steam turbines, generators, and their auxiliary devices). Coal fired power generation has a long history and is also an important type.

燃煤发电机组主要由燃烧系统(以锅炉为核心)汽水系统(主要由各类泵给水加热器凝汽器管道水冷壁等组成)电气系统(以汽轮发电机主变压器等为主)控制系统等组成。前二者产生高温高压蒸汽;电气系统实现由热能机械能到电能的转变;控制系统保证各系统合理经济运行。燃煤发电作为一种传统的发电方式也有其弊端和不足之处,如煤炭直接燃烧排放的SO2NOX等酸性气体不断增长,使得我国的酸雨量增加,粉尘污染污染对人们的生活及植物的生长造成不良影响。因此要不断地改进燃煤发电的行程,利用各种技术提高发电效率,减小环境污染,如对烟尘采用脱硫除尘处理或改烧天然气,气轮机改用空气冷却。

The coal-fired power generation unit mainly consists of a combustion system (with the boiler as the core), a steam water system (mainly composed of various pumps, feed water heaters, condenser pipes, water-cooled walls, etc.), an electrical system (mainly composed of the main transformer of the steam turbine generator, etc.), and a control system. The first two generate high-temperature and high-pressure steam; The electrical system realizes the transformation from thermal mechanical energy to electrical energy; The control system ensures the safe, reasonable, and economical operation of each system. As a traditional power generation method, coal-fired power generation also has its drawbacks and shortcomings. For example, the continuous increase in acidic gases such as SO2 and NOx emitted from direct coal combustion has led to an increase in acid rain in China, and dust pollution has a negative impact on people's lives and plant growth. Therefore, it is necessary to continuously improve the schedule of coal-fired power generation, use various technologies to improve power generation efficiency, and reduce environmental pollution, such as using desulfurization and dust removal treatment for smoke and dust or switching to burning natural gas, and using air cooling for gas turbines.

操作信息

Operation information

很多用户在使用柴油发电机组组的时候,一般情况是拿来主义,不懂得具体规范的操作流程,为您详细介绍一下

Many users, when using diesel generator sets, generally adopt a utilitarian approach and do not understand the specific and standardized operating procedures. Let me provide you with a detailed introduction

室内气温低于20℃时,开启电加热器,对机器进行预热。

When the indoor temperature is below 20 ℃, turn on the electric heater to preheat the machine.

检查机体及周围有无妨碍运转的杂物,如有应及时清走。

Check if there are any debris that hinders the operation of the machine and its surroundings. If there are any, they should be promptly removed.

检查曲轴箱油位燃油箱油位散热器水位。如油位水位低于规定值,应补充正常位置。

Check the crankcase oil level, fuel tank oil level, radiator water level. If the oil level and water level are below the specified value, they should be replenished to the normal position.

检查燃油供油阀和冷却水截止阀是否处于开通位置。

Check if the fuel supply valve and cooling water shut-off valve are in the open position.

检查柴油发电机组起动电动的蓄电池组电压是否正常。

Check if the voltage of the battery pack for starting the electric motor of the diesel generator set is normal.

检验配电屏的试验按钮,观察各报警指示灯有否接通发亮。

Check the test button of the distribution panel and observe whether each alarm indicator light is connected and on.

检查配电屏各开关是否置于分闸位置,各仪表指示是否处于零位。

Check if all switches on the distribution panel are in the open position and if all instrument indications are in the zero position.

启动进风和排风机。

Start the intake and exhaust fans.

按动发动机的起动按钮,使其启动运转。如次起动失败,可按下配电屏上相应的复位按钮,待其警报机组回复正常状态方可进行第二次启动。启动后,机器运转声音正常,冷却水泵运转指示灯亮及路仪表指示正常,启动成功。

Press the start button of the engine to start and run. If the first startup fails, press the corresponding reset button on the distribution screen, and wait for the alarm to clear before the unit returns to normal state before proceeding with the second startup. After starting, the machine operates with normal sound, the cooling water pump operation indicator light is on, and the road instrument indicates normal operation, indicating a successful start.
