AI Technical Summary
In existing forging production heating furnaces, there is insufficient waste heat recovery during the high-temperature heating process. The direct emission of waste heat from the high-temperature flue gas generated by fuel combustion leads to low thermal efficiency. Furthermore, the incomplete treatment of high-concentration iron oxide dust and metal particles results in frequent equipment shutdowns and resource waste.
Design a forging production heating furnace, which uses an axial flow fan to guide high-temperature flue gas to circulate into the insulation channel to form an inner insulation layer. Combined with a rotatable filter frame and a scraper system, it realizes automatic filtration and cleaning of dust in the flue gas. The waste heat of the flue gas is used to maintain the furnace temperature, and the dust is accumulated in the collection box for later recycling.
It significantly improves the overall thermal efficiency of fuel, reduces the energy consumption cost of forging heating, extends the continuous operation time of equipment, improves resource utilization, and reduces maintenance intensity and cost.
