Sinter Cooler Waste Heat Recovery BoilerNecessitySinter Cooler process is highly energy consuming and it accounts for 10% of the entire energy input in steel making process. Moreover,Website:http://www.chinawasteheatboiler.com, 50% of the energy being consumed in this very process is lost in the environment in the form of emitting waste flue gas into our atmosphere. It is due to both equipment inefficiencies and thermodynamic limitations of the equipment. Recovering waste heat emanated from this process makes sense for both environmental sustainability and prospective economical benefits. Design IngenuityOur boiler adopts inner thermal insulation pipe-box type structure to eliminate direct contact between flue gas and box steel frame. This structure not only ensures the safety of heat surface tube-box frame but also minimizes air leakage which is to lower heat loss & power consumption of induced draft fan, and increase overall operational efficiency. Heat surface adopts spiral finned tubes with high finned ratio & small diameter. This design enhances heat transfer and increases abrasion resistance. Also, all weld seam and elbow are located outside the gas passage which guarantees the long term safe operation of heat surface and provides convenience for maintenance. The average investment recovery period is only 1.8 years.Key Parameters 1 T Iron Ore = 120 KG ~ 150 KG of steam output HP pressure: 1.0 MPA ~ 2.5 MPAHP steam temp: saturated steam temp ~ 380℃LP steam pressure: 0.3 MPA ~ 0.8 MPALP steam temp: saturated steam temp ~ 260℃PROJECT SINTER COOLER 550 m2 WASTE HEAT RECOVERY FOR: BAOSTEEL GROUP CO., LTD. - ZHANJIANG PLANTHP steam output: 65 T / H @ 1.8 MPA HP steam temp: 360 Deg Celsius LP steam output: 20 T / H @ 0.4 MPA LP steam temp: 180 Deg Celsius (saturated temp)PROJECT SINTER COOLER 360 m2 WASTE HEAT RECOVERY FOR:JIANGSU SHAGANG CO., LTD.
