Compared with a fuel hot blast stove without waste gas waste heat recovery, the energy-saving hot blast stove can recover 20-30% of waste gas waste heat of a dryer, save 15-25% of fuel consumption, and has obvious energy-saving effect, and because the temperature of the recovered low-temperature drying section waste gas is always 30-40 ℃ no matter the ambient temperature is high, the humidity of the waste gas is below 70%, the temperature of the cooling section is 8-30 ℃ and the humidity of the waste gas is below 50%, the lower the ambient temperature is, the more obvious the energy-saving effect is, and a series of problems of high fuel consumption, high energy consumption and the like are solved.
