Abstract
The thermodynamics of the process of calcium sulfate decomposition is considered. An adsorbent for cleaning flue gases from sulfur dioxide in the form of sludge from alumina production is proposed. Conducted semi-industrial experiments on cleaning the flue gases of small thermal power plants and boiler houses from sulfur dioxide using a laboratory installation. Established high (more than 90%) the effectiveness of the proposed adsorbent. The unique possibility of flue gas cleaning from nitrogen oxides of thermal devices using lignite fuel is revealed. A scheme of sequential flue gas cleaning in a suspended and fixed bed of the adsorbent is proposed.
