  • Hybrid fluidized bed combuster
    Patent number: 4325327
    Abstract: A first atmospheric bubbling fluidized bed furnace is combined with a second turbulent, circulating fluidized bed furnace to produce heat efficiently from crushed solid fuel. The bed of the second furnace receives the smaller sizes of crushed solid fuel, unreacted limestone from the first bed, and elutriated solids extracted from the flu gases of the first bed. The two-stage combustion of crushed solid fuel provides a system with an efficiency greater than available with use of a single furnace of a fluidized bed.

  • Method for removing sulfur and nitrogen compounds from a gas mixture
    Patent number: 4167578
    Abstract: The Air Quality Control System utilizes the reaction between nitrogen oxides and the sulfites and bisulfites which are produced as a slurry of lime/limestone absorbs sulfur dioxide from a mixture of gases to produce ammonia from the absorption of nitrogen oxides.
