Learn Morehas remained in continuous operation since 1978 with two parallel trains each capturing 400 ton/day (363 mt/day) of CO2 from flue gas from a coal-fired boiler. The CO2 is used to carbonate brine for soda ash manufacture. The ABB Lummus Global Process, using a 15–20% by weight MEA solution with inhibitors, has also been used for CO2 capture

Learn More•Flue gas analysis –Oxygen or CO measurement is recommended to check whether proper air/gas ratio and firing is obtained –This is also for safety and furnace/boiler efficiency analysis •Pressure measurements –Pressure, both air and gas, should be measured at suitable points to check the firing condition and also their maintenance
Learn MoreOpen hearth furnaces are first charged with scrap and a small amount of limestone. Limestone is used as a reduction agent. Then the fuel—typically oil, natural gas, coal, tar and pitch, or a combination of these—is ignited to melt the charge (Fig. 6).As the charge melts, proportioned amounts of molten pig iron are added to the furnace and high-purity oxygen is blown in.
