Application of High Efficiency Utilization Technology for Low Quality Waste Heat Resources in Sintering
To achieve the full utilization of sintering waste heat,a series high efficient utilization technologies of sintering low quality waste heat resources were adopted,the joint-stock company adopts high-level flue gas circulation technology while generating electricity from the waste heat of the ring cooler,increasing the utilization coefficient of the sintering machine by 0.104 t/(m2h),and reducing fuel consumption by 3.35 kg/t.The flue gas external circulation process not only reduces the desulfurization and denitrification load by 15％,but also achieves carbon monoxide re oxidation and energy utilization,reducing fuel consumption by 0.3 kg/t.By adopting an annular cooling cycle process,the load of the bag filter is reduced while achieving the reuse of high-temperature flue gas,reducing fuel consumption by 0.5 kg/t.Install a boiler in the flue,with an hourly gas production of 20 t and a power generation of 15 kW h.Hot air ignition with residual heat from ambient cooling reduces gas consumption by 0.5 m3/t.Shougang Co.,Ltd.has taken various measures to effectively utilize sintering waste heat.
