With the increasing demand for environmental quality, switching from coal to gas combustion has become one of the directions for pollution control. In recent years, our company has undertaken a large number of coal-to-gas hot air furnace projects, accumulating mature experience in furnace retrofitting. We can provide reasonable coal-to-gas hot air furnace solutions according to customer needs and offer a one-stop service for production, installation, and follow-up.

Direct-fired gas hot air furnace

Primarily composed of valve components, burners, combustion chambers, secondary air distribution, and control systems.

Through the valve component, the burner nozzle is fully mixed with air and combusted, producing a clean high-temperature flame that is directly喷射 into the combustion chamber for complete combustion. This results in clean high-temperature flue gas, around 1000°C, which is then adjusted through secondary air distribution to the required temperature for the production process. The hot air is then channeled through a hot air duct into the drying equipment (such as an oven, drying cabinet, drum dryer, belt dryer, and fluidized bed dryer, etc.) to dry the material.

Hot air cleaning, high thermal efficiency, up to. Minimal auxiliary equipment, low investment cost, and good operating environment; easy to operate, manual/automatic control available; features automatic ignition, load adjustment, flame detection, and alarm function.

2. Indirect heat exchange gas forced-air furnace

Primarily composed of the combustion system, heat exchange system, control system, and exhaust system.

By burning through the burner, high-temperature flue gas is produced to heat the heat exchanger system. The heated air is then blown into the drying system by a fan. The thermal efficiency can reach 92%. When the hot air temperature in the drying system reaches the rated maximum temperature, the burner will automatically stop burning or switch to a low flame. Once the hot air temperature drops to the rated minimum temperature, the burner will reignite and resume operation or switch to a high flame, and the rate of temperature increase can also be controlled by adjusting the inlet valve.

High heat exchange temperature, high thermal efficiency, compact size, stable hot air temperature, long lifespan, and low maintenance costs.
