      Coal burning boiler ZDFR
      Coal burning boiler ZDFR
      Product Category:Hot blast stove series
      Fluidized bed coal-fired hot blast furnace (abbreviated as boiling furnace), its combustion mode is that the coal is broken into particles less than 10mm, through the coal feeder uniform speed into the furnace fluidized bed; The high pressure wind of the blower is shot into the belly of the furnace through the isobaric bellows from the numerous holes of the hood on the air distribution plate, and the scattered wind is aggregated into the "air cushion" to hold up the coal particles and the charge is fluidized boiling combustion. The coal particles and slag jump at high temperature, friction, collision and cracking, from large to small until burned out; This kind of combustion has the characteristics of large contact area between air and fuel, high relative motion speed, long residence time of fuel in the fluidized bed, fast combustion speed, high degree of burnout, energy saving and environmental protection. Therefore, it has been widely used and developed rapidly in industrial kiln.
      Product Introduction

      1.Product introduction

      Fluidized bed coal-fired hot blast furnace (abbreviated as boiling furnace), its combustion mode is that the coal is broken into particles less than 10mm, through the coal feeder uniform speed into the furnace fluidized bed; The high pressure wind of the blower is shot into the belly of the furnace through the isobaric bellows from the numerous holes of the hood on the air distribution plate, and the scattered wind is aggregated into the "air cushion" to hold up the coal particles and the charge is fluidized boiling combustion. The coal particles and slag jump at high temperature, friction, collision and cracking, from large to small until burned out; This kind of combustion has the characteristics of large contact area between air and fuel, high relative motion speed, long residence time of fuel in the fluidized bed, fast combustion speed, high degree of burnout, energy saving and environmental protection. Therefore, it has been widely used and developed rapidly in industrial kiln.

      2.Fluidized bed uses

      Boiling furnace can be used for rotary dryer, vertical dryer, hammer dryer, indirect dryer, slag micro powder vertical mill, air sweep coal mill or coal powder vertical mill, fertilizer slurry granulator, powder drying tower, waste heat generation heat, material frying pan machine, all kinds of semi-finished product dryer and other equipment heating; Can be widely used in industrial raw materials or products drying, roasting. Such as: slag, clay, sludge, calcium carbide slag, compound fertilizer, industrial gypsum, gypsum board, iron fine powder, quartz sand, yellow sand, laterite ore, sulfur concentrate, siderite, zinc leaching slag, white carbon black, coke, coal powder and slime, etc.

      3.Main performance and characteristics

      1.Wide fuel adaptability, combustible value of more than 6270kJ/kg (1500kcal/kg) of all kinds of bituminous coal, anthracite, and even coal liver stone, chain row furnace slag, oil shale, coal slime, biomass fuel;
      2.Furnace combustion temperature (850~1100t), uniform operating temperature, stable heating;
      3.High combustion efficiency, burnout rate can reach more than 99%, furnace thermal efficiency is greater than 94%;
      4.Easy ignition, long compression time, intermittent compression fire up to 16~48 hours, no need to reignite the furnace;
      5.The outlet temperature of hot flue gas can be adjusted, the heating load can be adjusted broadly, and the outlet orientation of heating flue gas pipeline is flexible.
      6.Ash slag carbon content < 1%, not easy to soften or bond, good activity, suitable for use as cement mixing material, easy to comprehensive utilization;
      7.Clean combustion, low nitrogen oxide content in the flue gas, low cost curing desulfurization can be used in the furnace, so that the sulfur in the coal to solidify into the slag;
      8.Realize mechanical and electrical integration control, intelligent design of thermal control, low labor intensity;
      9.Long service life of furnace lining, less wearing parts, low maintenance cost.
