Description

This report describes a project proposed by LIFAC North America, Inc., (LIFAC NA). The host site will be a coal-fired powerplant of Richmond Power Light in Indiana. LIFAC technology uses upper-furnace limestone injection with patented humidification of the flue gas to remove 75--80% of the sulfur dioxide (SO{sub 2}) in the flue gas. In the LIFAC process, limestone is injected into the upper part of the furnace where the temperatures are sufficiently high to calcine the calcium carbonate (CaCO{sub 3}) to lime (CaO), which reacts with the SO{sub 2} in the flue gas to form calcium sulfite (CaSO{sub 3}), some … continued below

Description

This report describes a project proposed by LIFAC North America, Inc., (LIFAC NA). The host site will be a coal-fired powerplant of Richmond Power Light in Indiana. LIFAC technology uses upper-furnace limestone injection with patented humidification of the flue gas to remove 75--80% of the sulfur dioxide (SO{sub 2}) in the flue gas. In the LIFAC process, limestone is injected into the upper part of the furnace where the temperatures are sufficiently high to calcine the calcium carbonate (CaCO{sub 3}) to lime (CaO), which reacts with the SO{sub 2} in the flue gas to form calcium sulfite (CaSO{sub 3}), some of which oxidizes to form calcium sulfate (CaSO{sub 4}). The flue gas leaving the boiler then enters LIFAC's unique humidification chamber which increases the water content of the flue gas and activates the lime to enhance SO{sub 2} removal. Reduction of SO{sub 2} emissions are approximately 75--80%. Spent sorbent is then removed, along with the fly ash by an existing electrostatic precipitator (ESP) or baghouse. 6 figs., 1 tab.
