Hot blast stove can be divided into electric hot blast stove, oil-fired hot blast stove and gas-fired hot blast stove according to fuel. According to structure, it can be divided into vertical hot blast stove and horizontal hot blast stove. Small hot blast stove is mostly single-return and double-return vertical structure, and large hot blast stove is mostly three-return horizontal structure. 1，立式双回程结ξ构
1. Vertical double-return structure
Vertical oil-fired and gas-fired hot-blast stove adopts the method of burner downside, two-way structure, abundant fuel burning, stable operation of hot-blast stove; there are spoilers in the flue pipe to slow down smoke exhaust speed, add heat transfer, high thermal efficiency of hot-blast stove, and reduce the cost of users. ,
2. Horizontal three-return structure
Horizontal hot blast stove is a three-way flame tube structure with full wet back and downstream flow. Flames are incinerated under micro-positive pressure in large incineration chamber. It extends thoroughly and has low heat load and high thermal efficiency. It effectively reduces smoke exhaust temperature, saves energy and reduces consumption, and makes use of economy. The structure of corrugated furnace gallbladder and threaded flue gas pipe not only improves the heat absorption intensity of hot blast stove, but also satisfies the demand of heat expansion of heat exchange surface. It is scientific, reasonable and durable.
