【Abstract】 Town gas premixed combustion within proted ceramic plaque was studied experimentally. The experimental rig of the town gas premixed combustion within the X type plaque was introduced and the thermodynamic parameters were measured, including the town gas composition, the flow of the gas and the air, the temperature of the gas and the air and the solid temperature profiles within the plaque under various heat flow. Meanwhile, the manufacturing engineering of X type plaque was introduced in brief and the parameters of the X type plaque were measured, including the three dimensions, bending strength, density, expansion coefficient and thermal conductivity.更多还原
