Direct coal-fired hot blast stove

Direct coal-fired hot blast stove MBZ direct coal-fired hot air stove is composed of MBL coal-burning machine, high-temperature gas purification room and air mixing room. The raw (bituminous) coal is fed into the coal hopper at one end of the coal-burning machine through the coal loading machine, and a certain height of the coal seam (the height of the coal seam can be adjusted according to the type of coal) is fed into the combustion chamber of the coal-burning machine at a uniform speed by the chain grate, and the combustion-supporting air It is sent into the distribution chamber by the fan, and enters the air chamber under the fire grate through the regulating valve, and then passes through the coal seam through the fire grate. Z30100×31 RADIAL DRILLING MACHINEThe volatile matter in the bituminous coal escapes first, and the fixed carbon fully contacts with the air on the chain grate to generate high-temperature flue gas, and the high-temperature flame is ejected from the fire outlet of the coal burner. The burnt coal slag is discharged from the other end of the coal burner to the slag discharger, and sent out through the automatic scraper slag discharger.Z3080 RADIAL DRILLING MACHINE The high-temperature flame enters the high-temperature gas purification room for secondary combustion, and the dust entrained in the flue gas is polymerized and deposited at a high temperature in the clean room. Aluminum alloy vacuum brazing of heat exchangers The clean hot air (~1000°C) coming out of the purification room is mixed with a certain amount of cold air, and the hot air mixed into the temperature required for material drying enters the drying equipment (such as spray tower, rotary kiln, oven, drying room, air dryer, fluidized bed, etc.) etc.) to dry the material. The temperature of the hot air can be adjusted according to the needs of the process, and the temperature stability of the continuous hot air is ±5°C.Prevention method for grinding cracks of vacuum carburizing and quenching gears
