| titleOfInvention | Double-chamber kiln online denitrification method |
| abstract | The invention discloses an online denitration method of a double-chamber kiln, which belongs to the technical field of lime kiln flue gas. When chamber A is calcined and chamber B is calcined for regenerative combustion, fuel is injected into the upper lance of chamber A to participate in the combustion, and the upper lance of chamber B is injected into The cooling air mixed with ammonia gas is used for denitration; when chamber B is calcined and chamber A is regeneratively burned, the spray gun of chamber B is injected with fuel to participate in the combustion, and the spray gun of chamber A is sprayed with cooling air mixed with ammonia gas for denitration. The two lances of the double-chamber kiln alternately inject fuel or cooling air mixed with ammonia into chamber A and chamber B, and the fuel lance in the kiln is also used as a lance for denitrification agent. Ammonia gas denitrifies the spray gun while cooling and protecting it, and expands the denitration radiation area with the help of the spray gun; at the same time, the cooling air mixed with ammonia gas is sprayed at the bottom of the double-chamber kiln to further improve the denitration effect of waste gas. The invention can always ensure that the kiln chamber that discharges the exhaust gas is always on-line for denitrification. |
