循环流化床锅炉是一种新型的高效、低污染的清洁燃煤锅炉。 Product introduction: Circulating fluidized bed boiler is a new type of high efficiency, low pollution clean coal-fired boiler. Its main feature is that a large amount of material is contained in the furnace of the boiler. During the combustion process, a large amount of material is carried by the flue gas to the upper part of the furnace. The separator is arranged at the exit of the furnace to separate the material from the flue gas and pass through the non-mechanical return valve. will
Circulating fluidized bed boiler is a new type of high efficiency, low pollution clean coal-fired boiler. Its main feature is that a large amount of material is contained in the furnace of the boiler. During the combustion process, a large amount of material is carried by the flue gas to the upper part of the furnace. The separator is arranged at the exit of the furnace to separate the material from the flue gas. The material is returned to the bed and burned repeatedly. Due to the high material concentration, large heat capacity and good material mixing, generally several kilograms of material can be carried per kilogram of flue gas. These circulating materials bring higher heat transfer coefficients, making the boiler heat load adjustment range wider. Better adaptability to fuel.
Circulating fluidized bed boilers use higher fluidization speeds than bubbling beds, but do not have an obvious interface like bubbling beds. Due to the strong turbulence and material circulation in the circulating fluidized bed, the residence time of the fuel in the furnace is increased, so it has higher combustion efficiency than the bubbling bed, and can run stably under low load without the need to increase auxiliary fuel. The circulating fluidized bed boiler operating temperature is usually between 850 and 900 ° C, which is an ideal desulfurization temperature range. In-furnace desulfurization technology is used, and limestone is added to the bed as a desulfurizing agent. The fuel and desulfurizing agent are repeatedly circulated at low temperature for combustion and desulfurization. In addition, the turbulent motion in the furnace is intense. When the Ca / S molar ratio is about 2, the desulfurization efficiency can reach about 90%, and the SO2 emission is greatly reduced.
At the same time, the circulating fluidized bed uses staged air combustion, so that the combustion is always performed under low excess air, thereby greatly reducing the generation and emission of NOX. Circulating fluidized bed boilers also have the advantages of high combustion efficiency, strong fuel adaptability (can use inferior fuel), good boiler load regulation, and easy comprehensive utilization of ash and slag, so they have developed rapidly around the world. With the increasingly strict environmental protection requirements, it is generally believed that circulating fluidized bed is one of the practical and feasible high-efficiency low-pollution coal-fired equipment.

Circulating fluidized bed boiler is a new type of high-efficiency, low-pollution clean coal-fired technology boiler. Its main feature is that the boiler furnace contains a large amount of material. During the combustion process, a large amount of material is carried by the flue gas to the upper part of the furnace and is arranged. The separator at the exit of the furnace separates the material from the flue gas, and sends the material into the bed through a non-mechanical return valve, which is repeatedly circulated and burned.
1. The unique structure design of the separator:
The membrane wall absorbs heat to the inner lining and allows the residual carbon in the flue gas to continue to burn in the separator without causing coking and improving the separation efficiency.
2. Patented design of return device:
The return material system adopts the patented membrane water wall technology, which makes the return material uniform and smooth.
3. Anti-wear design of buried pipe:
The buried pipe adopts anti-wear ribs with special angles and sizes to prevent the pipe from being worn. After the boiler is operated for a period of time (usually more than one year), measures such as repair welding and anti-wear tendons can be adopted to extend the life of the buried pipe indefinitely.
