Question details (Performance):1. High temperature of motor, fast temperature rise.2. Overload, high outlet pressure and frequent safety valve open often.3. The vibration is intensified, the side vibration of the fan motor coupling is large, and the fan body never vibrates to vibration.4. No obvious vibration was found in no-load test of fan motor. Answer: Fault reason:Fan bearing vibration is common fault in the operation, the vibration of the fan will cause damage of bearing and blade, bolt looseness, chassis and wind damage, fan vibration rises abruptly in the operation. this is because when the gas enter impeller and the rotating blade working face has certain angle, according to the principle of fluid mechanics, gas from non-working face must be a spiral blade, so the dust particles in the gas will slowly sedimentation due to vortex. Airfoil blades are very easy to accumulate dust. When the accumulated ash reaches a certain weight, a part of the large amount of accumulated ash wi

Designed to burn a variety of fuels cleanly and efficiently, these boilers have become a preferred choice for industries worldwide. Among manufacturers, ZOZEN Boiler has established itself as a global leader in providing state-of-the-art fluidized bed combustion boilers. In this article, we will explore the advantages of flu...
Understanding how a circulating fluidized bed boiler works is key to appreciating its efficiency in power generation and industrial heating. These boilers use a unique combustion process where fuel and inert particles are suspended in upward-flowing air, creating a highly reactive “fluidized” bed. Here’s a detailed breakdown of how a circulating fluidized bed boiler works and why it’s widely adopted.
The Mechanics: How Does a Circulating Fluidized Bed Boiler Work?Fluidiz...
The principle of primary and secondary air regulation in circulating fluidized bed (CFB) boilers is designed to maintain stable operating conditions of the boiler, adjusting the volume and temperature of primary and secondary air to achieve efficient combustion and reduce pollutant emissions. Specific adjustment strategies should be optimized and adjusted based on the boiler design and actual operating conditions.

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.
