Proper shutdown procedures are crucial for ensuring the safe and efficient operation of a coal-fired steam boiler. The following steps should be followed when shutting down a coal-fired steam boiler:
1. Reduce the load: Before shutting down the boiler, the load should be reduced to its minimum level. This will help to prevent sudden drops in pressure and temperature, which could cause damage to the boiler and its components.
2. Shut off the fuel supply: The fuel supply to the boiler should be ...
When it comes to coal fired boilers, the rear arch plays a critical role in the combustion process. The main function of the rear arch is to keep the fuel particles in suspension and prevent them from falling into the ash hopper, which can lead to incomplete combustion and decreased efficiency.
At ZOZEN, we understand the importance of a well-designed rear arch for coal fired boilers. That's why our coal fired boilers are equipped with advanced rear arch designs that enhance the combust...
The coal-fired boiler uses coal as fuel. The consumption of coal is a key factor to measure the efficiency of boilers. Under the same condition, the coal-fired boiler with less coal consumption can save more costs for enterprises. However, the coal consumption of coal-fired boilers is related to many factors, such as the efficiency of the boiler, the calorific value of fuel coal and the degree of coal combustion.
Question details (Performance) :
1. The vibrating coal grate stops running totally or intermittently.
2. The current of vibrating coal grate motor rises abnormally.
3. The safety clutch of transmission machine of grate or safety pin is broken.
Answer: cause of the problem:
Boiler’s vibrating coal grate is a rotating combustion equipment, due to the bad working conditions, stuck stalling is easily happened and grate failure happens in daily application and ...
Commonly used dust removal equipment of SZL boiler includes multi-tube dust collector, wet scrapper and bag filter.
1. Multi-tube dust collector: XTD type vertical ceramic multi-tube dust collector has the advantages of wear-resistance, high temperature resistance, corrosion resistance, low cost, etc. Its collection efficiency is not less than 95%, resistance is not higher than 900Pa and mainly removed dust granularity is greater than 20um.
Design, manufacture and acceptance of multi-t...
There are many factors that affect the operating cost of the boiler, among which the insufficient combustion of the coal-fired boiler directly leads to an increase in the cost of the boiler. Therefore, users should adjust in time during daily operation and use to avoid insufficient combustion of coal-fired boilers.
Causes and treatment of insufficient combustion of coal-fired boiler
1, Insufficient air volume; Need to increase the air intake,
2, poor ventilation, insufficient oxygen supply, s...
The fuel of the boiler needs to be determined in advance before the user adopts the equipment, and the calorie of coal used in the boiler directly affects the choice of the type of coal-fired boiler. Here, ZOZEN Boiler summarizes the calorific value of common boiler coal calories, hoping to be helpful to everyone.
Common boiler coal calorific value is 5500kcal/kg-7000kcal/kg.
China's power coal mainly includes bituminous coal, anthracite and lignite. Coal is mainly composed of carbon (C), hydr...
Coal-fired boilers use various types of coal as fuel. After the heat of coal is converted, steam is generated, which is often used in the production of heating, heating and thermal power generation. The model parameters of coal-fired boilers are different, and the cost is also different. Here, ZOZEN Boiler takes the cost of a 40-ton steam coal-fired boiler as an example for a brief introduction.
40 tons of steam coal-fired boiler cost
In addition to boiler room construction, EIA costs, transpo...
