Technical principle of MBZ direct coal-fired hot blast stove

MBZ direct-type coal-fired hot air stove is composed of MBL coal-burning machine, high-temperature gas purification room and air mixing room. This device uses a coal-fired machine as the first-level heat supply. The raw (bituminous) coal is added to the coal hopper at one end of the coal-fired machine through the coal feeder, and the coal seam of a certain height is fed into the coal-fired machine at a uniform speed by the chain grate. In the combustion chamber, under the action of the combustion-supporting fan, the high-temperature flue gas generated by coal combustion is ejected from the side fire outlet of the coal-fired machine into the high-temperature gas purification chamber. CVD Diamond Tool Brazing The high-temperature gas purification chamber is made of refractory materials, and the high-temperature flue gas undergoes secondary combustion in the purification chamber, and a small amount of dust entrained during the coal combustion process is polymerized and settled in the purification chamber by high temperature. The clean hot air (~1000°C) coming out of the purification room is mixed with a certain amount of cold air, and mixed to form hot air at the temperature (200-300°C) required for material drying, which enters the spray tower to dry the material (papermaking black liquor). Vacuum annealing process of steel ring 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. 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.M14 SERIES UNIVERSAL CYLINDRICAL GRINDING MACHINE Environmental protection up to standard, no secondary pollution, clean operating environment; high cleanliness of hot air, dust content <120mg/Nm3, no open flame in hot air; high thermal efficiency >95%;WHEEL GRINDER MOBILE PROGRAM CONTROLLED (CNC) CYLINDRICAL GRINDER
