Cylindrical body, the central cylinder, a cone, a loop seal, the material returning leg, from the high temperature flue gas out of the furnace, two left and right into the two cyclones, increase after turning flue flue gas velocity in the cylinder the center of rotation of the form cylinder back down into the cone upwardly from the central cylinder wall Shuaixiang excluded smoke particles under high effort when the cone reaches the end coupled with its heavy fall below the loop seal. 11, Refeeder role? The ash from the circulation loop seal into the furnace combustion chamber 12, acting characteristics superheater? The use of flue gas heated to a certain pressure saturated steam superheated steam. 13, bag filter works and composition? Principle: inlet flue gas-containing flue dust particles into the lower caul plate over the flue dust reduction chamber, and then through the outlet to reduce the wind speed of the flue draft fan withdrawn via the discharge plenum chamber clean flue upper portion of the bag filter the atmospheric composition: inlet flue, the caul plate, the reduction of flue gas chamber, bag, net flue gas plenum chamber exit gas, ash silo, rotating ash blowing device, the air reservoir. 14, to the mounting position of the coal feeder, the number, composition mounted on the front wall of the furnace, the number of stage three consists of: a motor, a belt coal feeder, reducer, the motor slide. 15, the process of slag from the furnace down the three tap outlet derived by the discharge of slag, after water cooling to cool to a certain temperature onto the cooling belt-type transfusion Pa, and then transported by the inclined transport slag to the slag bin .

Safety rules steam boiler steam boiler production, life indispensable important equipment. Boiler room is a vital part of my unit. Steam boiler having a high temperature, high pressure characteristics in use. Such as poor management, will be an accident, causing casualties, the production interruption caused serious losses to the school and state. So each time fireman and maintenance personnel to maintain a high degree of responsibility in their work to ensure the normal operation of the boiler, strictly adhered to. A strict compliance system fireman job, to play unity, mutual help support the spirit of love. Second, improve and maintain boiler equipment, keep boiler room tidy, attention and strive to save coal, water, electricity. Third, in the boiler operation to maintain a predetermined pressure, temperature, pressure must not exceed. Pay attention to discern false water level. Bearing in mind the piping, valves and the valve opening position of the distribution status of operation. Gradually closing the valve should be open or closed on the side of the handwheel. Always pay attention to the old boiler malfunction and run accident precursor, should understand the reasons for treatment and prevention of its occurrence. When the need for urgent and emergency shutdown. Keep in mind the role of the distribution board each button, leaving no more than a total pressure during shutdown and cut off the power supply. Fourth, coal hopper raised or lowered, the lower non-coal hopper to stand, the suction air blower, fan, Java machine, near the transmission gear portion, careful attention to production safety, to prevent accidents. Fireman must stick to work, and offenders a fine deal. V. PREPARATION carefully, to prevent explosive materials hazardous materials into the furnace. Plow winter freeze to prevent collapse injured seam. Coal prevent collision, twisting, crushing, usually using a tool in order. Around six, switchboard and non-flammable metal was stacked, and against dust, attention to fire prevention. Sewage on time, clean the filter in the soot. Seven, when circumstances such as fire or electrical failure in the event of boiler operation, should take urgent measures to monitor and report immediately. Eight, to be reasonable gas, save gas, stop running, take, leak, to prevent burns. IX When the boiler room accident, failure in dealing with accidents, incidents and unclear responsibilities, fireman shall not leave the boiler room. Ten, who caused the accident, were the situation to criticism and other penalties for illegal operations. XI, each class set up a part-time security officer, the implementation of strict supervision, safety procedures, the implementation of the security staff of personal responsibility.

Cause of abnormal gas steam boiler stall phenomenon gas steam boiler and treatment of non-normal stalling reason, phenomena and treatment 2013-1-139: 17: 30 to cause a flameout: 1, or the operation of the auxiliary trip power outage. 2, boiler combustion instability. 3, the load is too low, so that the load sharply mill automatic ignition energy loss or failure of combustion. 4, mutant coal, volatile or low calorific value gas. 5, the automatic combustion flame detector failure or failure caused by tripping mill. 6, or blast furnace wall tubes serious improper boiler soot-blowing operation, a large amount of water vapor into the combustion chamber. 7, coal pulverizing system, fuel system failure, resulting in a significant amount of fuel reduction or interruption. Or with a large amount of water in the fuel oil gun blocked too many impurities, low pressure steam or atomized. Second, the phenomenon: 1, a significant increase in furnace pressure, furnace flame monitoring flameless CRT display. See the fire no fire hole, BTG warning window MFT warning lights. 2, the unit load decrease, the steam flow drops rapidly, each segment working medium temperature, the vapor pressure decreases, the value of oxygen surge. Third, the method of treatment: 1, if the MFT tripping protection, should an emergency shutdown processing, stop the supply of fuel. 2, identify the cause flameout, and try to eliminate, to conduct a comprehensive inspection of the boiler, after confirming the device properly, can restart.
