The tiles used for decorating which are heated by catalytic combustion furnace are more fine and glossy than the conventional ones, moreover, pollutant emission produced in productive process is much less than before. This conclusion may provide a new way to glazed tile heating industry, and at the same time, provide a general method of using the catalytic combustion furnace.展开更多
