The arrival of the heating season makes us realize that improving the efficiency of heating coal-fired boilers is crucial for comfortable indoor warmth. As a well-known heating equipment manufacturer, ZOZEN Boiler is committed to providing efficient and reliable coal-fired boiler solutions. The coal-fired chain grate boilers produced by ZOZEN can be divided into four series: SZL series double drum longitudinal chain grate boiler, DZL series single drum longitudinal chain grate boiler, DHL series...
Volatile matter in fuel, particularly in solid fuels like coal or biomass, plays a crucial role in the combustion process within boilers. Understanding the effect of volatile matter can help optimize the boiler operation for better efficiency and emissions. Here are the impacts of volatile matter on boiler combustion:
Ignition and Combustion Stability: High volatile matter content aids in the easy ignition of the fuel. As volatile components release and ignite rapidly when the fuel is heated, t...
What are the procedures and formalities for the retrofit of a coal-fired boiler?
The procedures and formalities for retrofitting a coal-fired boiler can vary depending on the specific regulations and requirements of the region or country. However, there are some general steps that are typically involved in the retrofit process:
1. Feasibility Study: The first step is to conduct a feasibility study to assess the technical and economic viability of the retrofit project. This invo...
The amount of coal burned by a large 660 MW boiler in one hour would depend on several factors such as the calorific value of the coal, the efficiency of the boiler, and the load at which the boiler is operating. However, as a rough estimate, a 660 MW boiler operating at full load and with an efficiency of around 38% would burn approximately 250 metric tons of coal per hour.
It's important to note that coal consumption can vary widely depending on various factors, such as the quality of...
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 ...
