Bubbled into the gasifying agent, first passes through the slag layer and in the layer to obtain preheated. When the fuel rises into the hot layer, carbon and oxygen in the following reaction: 2C + 02 = 2CO + Q ↑ 2C + 02 = CO2 + Q ↑ Since the reaction of this layer is so high exothermic temperature, this layer called oxide layer. Hot gas oxide layer continues to rise, with the top two gas furnace fuel contact, resulting in a reduction reaction. The main reaction is the main reduction layer: CO2 + C = 2CO-Q ↓ C + 2H2O = CO2 + 2H2-Q ↓ C + H2O = CO + H2-Q ↓ times reduction layer is mainly generated by the reaction of carbon monoxide and water vapor excess: CO + H2O = CO2 + H2 + Q ↑ generate methane in addition to side effects: C + 2H2 = CH4 + Q ↑ hot gas generated in the reduction layer and then further increased heating of the upper coal seam, forming a carbonization layer and dry layer. The role of volatiles in the carbonization layer of hot gases rise brings physical hot, dry distillation and evaporation is out; dry layer of water is by this heat is dry and clean. Generated gas gathered in the empty layer, through the gas outlet pipe into the purification device, and then for gas equipment. Gas produced; core technology architecture homemade gas heat treatment furnace equipment homemade gas heat treatment furnace equipment for furnaces and heat treatment furnaces are generated by the two parts together to form a perfect gas; gas furnace gas production to meet the different time periods of heat required heat treatment furnace mixed semi-water gas, heating value is high; full use of the gas and soot heat, energy saving. Gas furnace part is the introduction of absorbing the advantages of large-scale gas furnace at home and abroad on the basis of combined heat treatment furnace characteristics and the actual situation of the domestic coal gas furnace design. Main features: 1, the temperature in the heat treatment furnaces up to 1100 ℃ -1200 ℃, after a two-stage gas furnace can operate, set the whole process of realization of the technology curve and computer processors by PID control based on user requirements for heat treatment process . 2, the gas furnace slag dumping bodies rotating tower, strong slag dumping slag breaking ability. Slag discharged into the seal pool, no dust flying. 3, less environmentally friendly coal two gas stoves, using very low cost. (In installed furnace capacity of 4 tons when dealing with a ton Mn13, coal consumption is only about 0.15-0.25 tons; installed furnace capacity 30 tons, 0.15 tons less coal) 4, the production process, no visible smoke (fog) emissions no gas leak two gas furnace manufacturers, environmental protection standard completely, and made of environmentally friendly products recommended certificate Henan Province Environmental Protection Association. 5, the production process is safe and reliable, and continuous production. 6, the unique design of the heating system, the furnace temperature difference within ± 10 ℃; Unique burner design, the oxide layer of the workpiece little decarbonization. 7, may be the country's first automated computer control of the whole process of two gas stoves, Dahua Machinery (certified), two gas stoves provided by Gongyi City Dahua Machinery Limited. Gongyi City Dahua Machinery Co., Ltd. (www.dhyqj.com/) is a leader in Zhengzhou, industry-specific equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
