Gas hot blast stove is fueled by natural gas, blast furnace gas, coke oven gas, generator furnace gas, mineral furnace tail gas, etc. It is composed of gas pipe valve group, burner, air distribution device, combustion chamber and thermal control system. The shell of the combustion chamber of the furnace body is double-ring steel structure, and the front chamber is the furnace, lined with fire-resistant insulation layer; The rear chamber is the mixing hot air chamber, where the hot air from the furnace and the cold air from the ring gap are mixed simultaneously. By adjusting the gas amount of the burner and the opening degree of the air butterfly valve to control the intake air volume, the hot air temperature of heating can be adjusted. Widely used in various industries of drying and medium heating.
1.The furnace fuel has a wide range of applications: natural gas, coke oven gas, liquefied gas and other fuels. Large adjustment flexibility of heating load capacity , heating temperature 150-900C adjustable, thermal efficiency can reach 96%.
2.The combustion machine is advanced in domestic technology, simple structure, economical application, good burnout rate, high combustion efficiency. The method of combining multiple internal mixing and wind dispersion is adopted, that is, air and gas are mixed twice to ensure that air and fuel gas are fully mixed, so that the combustion is stable and efficient.
3.The combustion machine has a high degree of automatic control, simple operation, reliable performance, with PLC as the control core, humanized preparation of the start and run procedures, as long as the operation of the start button.
4.The control system is equipped with flame out alarm controller and temperature sensor,. Just press the start button, it can easily realize the starting of the burner fan, automatic purge, automatic ignition, automatic air supply, air supply. Abnormal flameout immediately send out alarm signal, and delay the fan shutdown.
