Main technical introduction:
Deliver high temperature waste gas from cooler (annular cooler or belt cooler) of sinter machine into waste heat boiler to generate super heat steam, and this steam can be collected to pipeline or for power generation.
Waste heat recovery method:
(1) Closed type circulating waste heat recovery system
(2) Open type circulating waste heat recovery system
(3) Waste heat hot water preparation system
(4) Hot water circulating air technology (researched & developed by SDM)
Main technical index:
System air leakage is less than 25%;
Power generation capacity per ton ore is high temperature waste gas;
Middle pressure steam output per ton ore is 85～95kg;
Ex-supply low pressure steam output per ton ore is 20～25kg.
