Air distribution system of the blast furnace gas burner has burners forced air supply and the low-frequency induced draft negative regulator for users to choose two types, combustion, high strength flame. Application requirements and operating principles with the view of blast furnace gas burner

The use of blast furnace gas burner requirement
The use of blast furnace gas burner demanding. Blast furnace gas burner is a blast furnace for iron and steel enterprises produced exhaust and planning, the use of any pressure, any blast furnace off-gas calorific value, can take the initiative to complete combustion and other functions. Hot gas heat source is a heating apparatus (boiler, industrial furnace, etc.), special equipment for hot gas combustion process is completed. Action is based on a certain percentage and mixing conditions must be hot combustion gas and combustion air is introduced into the burner or combustion in the heating apparatus, the heating process and the satisfaction of the flame direction, shape, rigidity and spreadability requirements. It has a wide target group, there are boilers, smelting furnace, furnace, heat treatment and other fields, and energy-related operations, the combustion system is essential. Blast furnace gas burners working principle is: the use of high calorific value gas as combustion fuel combustion burner lit, the lit burner ignition combustion, the flame is prospecting for exploration into the fire burner, the main gas pipe valve to open, gas from the gas nozzle strands into the combustor flame tube, after vigorously mixing the combustion Qiangdian radial swirler with air, and then the axial, tangential to the small strands uniformly mixed air, as a flame-like jet stream into the furnace . Flame-tailed exploration is the exploration rush combustion flame and the main fire and found flames burning suspend promptly send a signal to the controller, turn off the gas valve, cut off the delivery of gas, blast furnace gas burner flame to ensure safety. Blast furnace gas burner for industrial furnaces nipple oil or gas burner or the gas fuel to burn as a generic term by the use member, the core member furnace. Therefore, the higher its requirements: high combustion efficiency, at lower air ratio, the arrival completely burned. Stable combustion, a large load can be habit changes, scheduling large ratio, the combustion temperature process requirements can be satisfied. Flame performance, high speed and with greater rigidity, the radiation intensity was modulated. There was a higher heat recovery tone, can be manifested in the use of preheated air or preheat gas was adjusted, to reduce energy consumption. Fit safety and environmental rules, such as blast furnace gas burner noise, less harmful gases, less soot. Simple structure, simple operation, convenient repair, low cost, the use of long life.
