| titleOfInvention | Method of supplying reducing agent for exhaust gas denitration |
| abstract | (57) [Summary] [Structure] In an exhaust gas denitration system by selective catalytic reduction, an aqueous reducing agent was introduced to the downstream of the denitration catalyst bed of the exhaust gas duct and preheated to the vaporization or reaction temperature by exhaust gas exhaust heat. Then, it is injected into the exhaust gas duct at the upstream side of the catalyst bed. Further, in the above method, the flow rate and pressure of the reducing agent after preheating are controlled. [Effect] Exhaust gas is not deprived of the heat of vaporization, and the optimum reaction temperature for the reduction denitration catalyst of about 350 ° C. can be maintained. Therefore, it is possible to prevent a decrease in catalyst activity due to a decrease in exhaust gas temperature and a catalyst poisoning due to SO 3 . Since the heating of the reducing agent in the form of an aqueous solution is performed by utilizing the exhaust heat of the exhaust gas, new heating means and heat energy are not required. By controlling the flow rate and pressure of the reducing agent after preheating, the amount of reducing agent injected into the catalyst bed upstream can be changed rapidly, so that the amount of reducing agent supplied can be changed immediately in response to a sudden change in NOx concentration. Can be increased or decreased. |
