Within a internal CFB boiler the circulating bed material flows through the furnace together with the fuel and air. Combustion gases are then separated from the solid material with cyclones and any solids are returned to the lower part of the furnace while the gases pass on through the boiler.

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 boiler.

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.

What should be equipped with safety accessories boiler safety valve, explosion-proof doors, security seal, a low water level control alarms. Safety devices: a flow meter, pressure gauges, thermometers, fortune controller, water table and protection devices. Protection device: low water level alarm, low water interlock protection, vapor overpressure protection of the alarm and interlock devices, process control and ignition flameout protection devices. A safety valve the pressure in the boiler is controlled within the allowable range to ensure the safe operation of the boiler. When it exceeds a predetermined value, it can automatically open the exhaust steam, pressure relief, to prevent over-pressure boiler accident. Pressure gauge to measure the actual size of the boiler meter, pressure gauge value according fireman art, adjusting the lift of the boiler pressure, the boiler to ensure safety in the allowable working pressure. The role of water table is indicative of the high and low water level in the boiler, the water level in the boiler fireman help dynamic monitoring personnel to the boiler water level control in the normal magnitude of the boiler to prevent the occurrence of lack of water or full of water accidents. When the role of the vent is mild explosion in the furnace or the flue, can open their own relief, to avoid accidents and expand occur.

Compared down, condensing boiler has so many benefits, the price is certainly higher than ordinary boilers. After all, condensing boilers also called a set of technology and quality in one of the elite. But expensive is certainly expensive, makes sense, in addition to the environmentally friendly energy condensing furnace life is also higher than ordinary boilers, more cost-effective.
