Hot stove device and hot stove operation method

摘要

The hot stove device 1 uses a hot stove 4 for performing a blowing operation for blowing hot air into the furnace 2 and a combustion operation for burning fuel gas in the furnace 2, and BFG obtained from the furnace 2 as fuel gas. As examples, it has a fuel gas supply line 5 supplied to the hot stove 4 and a blower 52 installed in the fuel gas supply line 5 to boost BFG. The fuel gas supply line 5 takes out BFG from the downstream side of the furnace static pressure recovery facility 35 of the furnace top gas recovery line 3 which takes out BFG from the furnace top 21 of the furnace 2. The power of the blower 52 is supplied from an exhaust pressure recovery facility 441 that recovers back pressure and heat from exhaust gas of the hot stove 4 during combustion operation.
