Abstract

A small scale combustion unit was built to evaluate the CO suppression effects by various chemical additives added to coal briquettes. Among the additives tested comprising various transition metal compounds with catalytic activities, natural minerals and oxidizing agents, the copper component has shown the best CO suppression effect, and in particular, copper oxide dispersed on porous supports such as ${\gamma}-Al_2O_3$ was most effective. For instance, 0.5% of copper added to coal briquettes in this way bas exhibited 1.4 % CO in the combustion gas at the ignition and beginning stage of combustion and 0.3 % CO at the final stage. The effects of calcium compounds on the fixation of sulfur in coal were also evaluated to reduce the contents of sulfur compounds in the combustion gases.
