![]() Kiln feed system operating points early
1 , notify the post before feeding each professional reconfirmed each device system to normal . 2 , and gradually increase
the amount of exhaust system , start kiln fan system, pay attention to controlling the negative pressure in the kiln -20Pa about keeping kiln flame shape . 3 , when the smoke chamber kiln temperature above 1000 ℃, the system is ready to start feeding feeding . 4 , cast before feeding , from top to bottom with compressed air preheater should be purged again. Low yields feed production , should one hour purge once ; steady production, two hours purging once. Open the electric flow metering valve positions under the raw material feeding 5 , kiln smoke chamber temperature of 1000 ℃, decomposition furnace outlet temperature of more than 800 ℃, C1 tube kiln while exports amounted to 450 ℃ . By monitoring the initial raw material feeding amount of solids flowmeters at around 250 ~ 280t / h. If C1 outlet temperature curve has slipped into the description of the raw material preheater, you should pay attention to controlling the amount of coal fed to keep the smoke chamber kiln temperature 1050 ℃ ~ 1100 ℃. By observing C5 into the kiln feed material temperature has been confirmed into the kiln . Epigenetic feed material from the C1 stage preheater kiln to only about 30 seconds , in addition to close attention to the first one-hour pre-heater , you should pay attention to the flap valve at each temperature change after flashing and found flashing signs are not flexible or only blockage to timely treatment . Initial ignition as a precautionary measure , the head of a class cyclone levels flap should be supervised setting , or to adjust the timing of artificial flashing hammer to help nesting . After preheating system without exception may be the normal inspection tour . Cyclone cone is the most easy to plug parts, should pay attention to early feeding may be appropriate to increase the cyclone circulation density and wind blocking purge purge time , and then gradually to normal. At about 20 minutes after the start feeding normally , felt material with powder coming after firing segment can be adjusted according to actual situation kiln speed , avoid raw sprang . This phase was observed in the kiln to be careful to avoid return fire burns. 6 , in setting the amount of feed is carried out feeding . Adjust the cold air valve opening , high temperature fan inlet temperature does not exceed 400 ℃. 7 , coal stove set 2t / h, starting calciner feed coal group , C4 feeding tube under a dosing valve two points into the calciner , since the beginning of the use of bituminous coal , initially for men for the next feeding tube feeding, due to the smoke C4 cutting room temperature and high temperature , the basic guarantee of pulverized coal combustion in the calciner and materials endothermic decomposition , with the increase in production, according to the body temperature of the furnace and the furnace outlet temperature changes , proper feeding of material into the men tube , specifically the proportion of material in the production of the actual situation . Specializing in the production of rotary kiln in Henan YuFeng Heavy Equipment : The main products are : lime kiln , rotary kiln , ceramic sand | sand rotary kiln , rotary kiln calcium aluminate powder , laterite nickel ore rotary kiln, rotary kiln magnesium , zinc oxide rotary kiln , bauxite rotary kiln, rotary kiln oil proppant , disc granulator, wind swept coal mill , ball mill, preheater , burners, coolers , etc. Welcome new and old customers to our company to negotiate!
