Research on Lifetime of Catalytic Combustion Monolith inside Natural Gas Burner

摘要

This article discussed the factors that affect the lifetime of catalyst. For the lifetime of catalyst about catalytic combustion burner III 1100 hours were obtained. The local surface temperatures of monolith, the gas temperature inside channels and pollutant concentrations were measured. The ageing of catalyst to the change of local surface temperatures and gas temperature was approached and its affecting factors were analysed. This will improve the working conditions of catalytic combustion burner in future, and prolong its lifetime of catalyst.
