Some fundamental research work was conducted on the performance of the catalytic combustion water heater for household utilization and the activity of its combustion catalysts.We mainly changed the structure of current household nature gas water heaters and the method of the combustion.In the research work,the technique of catalytic combustion was applied,and the results show that the advantages offered by the catalytic combustor is that catalytic combustion can be carried out over a wide range of fuel concentrations in air and at low temperature.Moreover,NOx emission is much lower than that of conventional combustors,making use of fuel energy environmentally and efficiently.
