Guide: Coal-fired boilers have always been one of the most important furnace types in the industrial production field. From operating costs to boiler output status, etc., play an important role in the operation of enterprises. So why do we need to add some water to the fuel of coal-fired boilers before entering the furnace? What points should be paid attention to in the daily maintenance of coal-fired boilers?
Coal-fired boilers have always been one of the important furnace types in the industrial production field. From operating costs to boiler output status, etc., play an important role in the operation of enterprises. Then why do we need to add some water to the fuel of coal-fired boilers before entering the furnace? The daily routine of coal-fired boilers What points should be paid attention to in maintenance?
Purpose of adding water to coal
The first purpose is to prevent waste. Adding water to the fine coal powder can prevent the fine powder from being blown away with the blast, which is beneficial to let the coal powder stick together.
The second purpose is to improve combustion, reduce the unevenness of the fire bed caused by uneven coal particles, and improve fuel combustibility.
Purpose 3, increase the ignition, the coal is relatively dry, and the volatile matter is difficult to precipitate. Appropriate addition of water can improve ignition.
Coal-fired boiler Daily maintenance
1. Meter + valve, such as boiler pressure gauge, water level gauge, safety valve, sewage installation, water supply valve, steam valve. Check whether the request matches.
2. Monitoring facilities, check whether the flame detector, water level, water temperature detection, alarm installation and various interlock installations are normal.
3. Whether the fuel supply, fuel reserve, transportation route, combustion equipment, incineration equipment, etc. are normal.
4. Whether the ventilation system, blast, induced draft fan, regulating door and gate opening, and ventilation ducts can operate normally.
