The waste gas incineration energy-saving heating system of the 30000 t/a rock wool production line designed and constructed by Meibao has been put into operation. The system recycles and incinerates all the waste gas generated by the cupola of the rock wool production line, saving about 1.5 million yuan of natural gas fuel cost annually, with obvious energy saving and consumption reduction effect. This technology has been adopted by more than 50 rock wool manufacturers and has obvious economic and environmental benefits.
