Lujiang County, Anhui Province People's Government to strengthen the special equipment safety supervision, eliminate security risks, protect people's lives and property safety, recently, market supervision arrangements father of the rule of the mountain to carry out a special inspection of the fluidized bed boiler in fluid mechanics.
The area under the jurisdiction, boiler unit 10, involving 13 sets of boilers, mainly for industrial enterprises, food production enterprises. The audit focused on with the operation of the boiler, the boiler nature of the situation (coal, electricity, gas, biomass, etc.), verification test cases, water quality monitoring, troubleshooting, case workers certified, the implementation of the system, etc. . Examination revealed there is some use of units overdue inspection, the main responsibility is not implemented and so on, law enforcement officials immediately issued special equipment safety supervision instructions, the use of units ordered to stop using, to urge the rectification.
Poor water quality caused by damage to the fluidized bed boiler in fluid mechanics: poor water quality, means the water contains a lot of impurities. Boiler feed water may contain impurities in the raw water are: suspended solids, colloids, organic matter, inorganic salts, heavy metal ions, and the dissolved gas. If this water without any treatment, once inside the boiler, will bring the following hazards:
1, leading to the fluidized bed boiler in fluid mechanics room outside the doors should open outwards. Each boiler room should be at least two outlets, are provided on both sides. When the total width of the front end of the boiler (the boiler comprises a passage between the inner) of not more than 12m, and a boiler room area not exceeding 200m2 single boiler room and to be open only one outlet.
2, the boiler room door should not be used on a pull-down shutter doors or sliding door, single evaporator rated less than or equal 2t / width and height h of the boiler door homeowners boiler boiler assembly generally not less than the maximum dimensions plus 0.5m .
3, the ground should be flat boiler room without a step, no water in the boiler room floor drain hole (groove) should be set up at, to facilitate drainage.
4, boiler room should comply with building "architectural design code for fire protection" and "design of tall buildings for fire protection" requirements.
5, between the boiler wall (1.5 meters or less from the ground) should adopt cement plaster or tile veneer moisture protection and to facilitate washed with water.
6, boiler room operation site, as well as water gauge, pressure gauges, thermometers, flow meters, etc., should have adequate lighting.
7, operation of the boiler room should be open layout, and boiler water, boiler pressure measurement and control instruments concentrated in the operating room, and boiler and safety accessories should be reliable rain, wind, frost, anti-corrosion measures.
8, located in the wood workshop, no fireproof partition wall of the boiler, the application of non-combustible material, fire resistance of 4h material masonry firewall, the firewall directly on the basis of the masonry or reinforced concrete frame, the firewall should be cut off burning body or difficult to burn the roof structure, the roof and the body should be higher than 400mm non-combustion, combustion or higher hard body burning roof 500mm.
This article describes a typical South African sugar factory fluidized bed boiler in fluid mechanics, the analysis of boiler fuel and discusses the calculation of boiler efficiency. The figures that are used are generic and are not to be taken definitively.

Fluidized bed. The fluidized state occurs when a fixed bed of the particulate material is penetrated in the vertical direction with fluid at sufficient velocity to break up the bed. In a fixed bed, the particles are immobile, leaning on one another at numerous contact points and applying forces to one another.Online chat
Fluidized bed combustion is a combustion technology used to burn solid fuels. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials through which jets of air are blown to provide the oxygen required for combustion or gasification. The resultant fast and intimate mixing of gas and solids promotes rapid heat transfer and chemical reactions within the bed. FBC plants are capable of burning a variety of low-grade solid fuels, inclOnline chat
