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 ...
15t coal-fired steam boiler refers to the boiler equipment which takes all kinds of coal as fuel, generates 15t steam per hour under the rated working pressure after the heat of coal is converted. When purchasing a 15t coal-fired steam boiler, users need to pay attention to the analysis of technical parameters, which is not only related to the purchase price, but also determines whether the daily heat demand can be met in the later period. Here, ZOZEN Boiler focuses on introducing the common 15t...
Chain grate boiler is a kind of mechanized combustion boiler equipment which is widely used in industrial boilers. The chain grate is an important part of the grate, which is a consumable part. It is in direct contact with the burning fuel, so the selection of heat-resistant temperature is especially important. What is the highest temperature that a chain grate can generally bear?
Generally, the high temperature that chain grate can bear is directly related to the material. The heat-res...
It can be found that there are the following differences between vertical coal-fired hot water boiler and horizontal coal-fired hot water boiler by analyzing the structural diagram of vertical coal-fired hot water boiler:
The heat transfer of vertical coal-fired hot water boiler and horizontal coal-fired hot water boiler
The exhaust gas flow produced by the vertical coal-fired hot water boiler flows vertically to the heating surface from top to bottom, and the exhaust gas temperatu...
Boiler slag removal system is an important auxiliary device for biomass boiler, coal-fired boiler, circulating fluidized bed boiler and other boilers, which plays the role of slag removal. However, a small number of users still choose manual slag removal. Here, ZOZEN Boiler will explain to everyone what the importance of boiler slag removal system is, to help users make a reasonable choice.
Boiler slag removal system
The components of boiler slag removal system are different according ...
