Title:
COMBUSTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/179075
Kind Code:
A1
Abstract:
Provided is a combustion system using a catalyst having better denitration efficiency at low temperatures compared to the prior art, during a selective catalytic reduction reaction in which ammonia is used as a reducing agent. This combustion system comprises: a combustion device that combusts fuel; an exhaust path through which flows exhaust gas generated from the combustion of fuel in the combustion device; a dust collection device that is arranged on the exhaust path and collects soot/dust in the exhaust gas; and a denitration device that is arranged on the exhaust path and removes nitrogen oxides from the exhaust gas by means of a denitration catalyst, wherein the denitration device is arranged downstream of the dust collection device on the exhaust path, and the denitration catalyst contains vanadium oxide, has a carbon content of 0.05 wt% or more, and has a defect site in which oxygen deficiency occurs in a crystal structure.
