In the whole drying process, we should pay attention to gradually increasing the temperature instead of burning by raging fire; regularly checking boiler's water level and keeping it within the normal range; keeping the flame balanced in the furnace. In addition, we also should properly open the drainage valve and maintain the water level, regularly record the flue gas temperature to control the rise of temperature and high temperature and keep the temperature within the normal range. In general, under these conditions, boiler’s drying quality can be ensured.
The air oxygen content's effect on the boiler is mainly reflected by the effect on the blowing rate. Boiler will have typical phenomena if the blowing rate is high or low.
The coal-fired boiler has always been one of the important boiler types in the industrial production and its operating costs and capacity play an important role in the enterprise operation.
Because coal fuel is expensive and coal combustion can cause serious environmental pollution, it is necessary to transform the coal-fired boiler into gas-fired boiler. However, the reconstruction of coal-fired boiler is not a small project. Only pay close attention to every phase of the reconstruction process can avoid failure.
Serious coal leakages in the fire grate of coal-fired boilers can be caused by several factors, each impacting the efficiency and safety of the boiler operation. Understanding and addressing these issues is crucial for maintaining optimal performance. Here are some common causes:
Wear and Tear: Over time, the fire grate components can wear down due to the constant exposure to high temperatures and the abrasive nature of coal. This wear can create gaps through which coal can fall.
Improper Grat...
Boiler classifications, including "D-grade", are typically based on factors such as pressure, temperature, and capacity. The specific parameters for classifications can vary by country and standardization organization. However, generally speaking:
D-grade boilers often refer to boilers that operate at relatively lower pressures and temperatures compared to high-pressure industrial boilers. They are typically:
Low-Pressure Boilers: D-grade boilers might be designed to operate under specific pre...
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...
Circulating fluidized bed (CFB) boilers are a type of combustion technology that is commonly used for power generation and industrial applications. The following are the characteristics and working principle of circulating fluidized bed boilers:
Characteristics:
High combustion efficiency: CFB boilers have high combustion efficiency due to the large surface area of the bed particles and the high turbulence created by the fluidizing air.
Fuel flexibility: CFB boilers ca...
