Description

Technical Field

[0001] This utility model relates to the field of direct-fired furnaces, specifically a high-efficiency, energy-saving, and stable direct-fired TO furnace. Background Technology

[0002] A direct-fired TO furnace is a device that uses the heat generated by the combustion of auxiliary fuel to raise the temperature of combustible and harmful gases to the reaction temperature, thereby causing oxidation and decomposition. It is mainly used to treat VOCs (volatile organic compounds) and other waste gases, decomposing them into CO2 and H2O through high-temperature oxidation, releasing a large amount of heat energy. The direct-fired TO furnace heats the furnace to a set temperature using fuel, then introduces the waste gas to be treated into the furnace. Under high-temperature conditions, pollutants are oxidized and decomposed into CO2 and H2O, releasing heat energy. This heat energy can be recovered and reused through matching heat exchangers, boilers, and other equipment, achieving energy saving and consumption reduction. When the waste gas concentration is high enough, the furnace temperature can even be maintained by the heat released from the oxidation of the waste gas itself, achieving heat self-balance. The design of a direct-fired TO furnace is flexible and diverse, and can be customized according to the characteristics of the site space, such as a square cavity or a cylindrical cavity. Heat recovery devices, such as heat exchangers and boilers, can be installed outside the furnace to further optimize energy utilization efficiency. In addition, the combustion system of the direct-fired TO furnace is internationally certified, has high safety, stable system operation, and is suitable for fully automated control, reducing personnel input and maintenance costs.

[0003] However, most of the high-efficiency, energy-saving, and stable direct-fired TO furnaces currently on the market cannot purify the exhaust gas, which in turn pollutes the surrounding air, thus reducing the environmental conditions around the workplace and increasing safety hazards.
