According to the metal honeycomb heating element for the gas stove , the the porosity of the lower end of the honeycomb body is low, gascan pass through the lower end of the honeycomb heating element body with a higher speed, the lower end of the honeycomb heating element body can be better cooled, and thus the purposes that flames are prevented from spreading to the lower end of the honeycomb heating element body, the burning stability is high, and backfire is not likely to occur are achieved; and besides, the porosity of the upper end of the honeycomb heating element body is high, it is beneficial to efficient burning of gas, the heating speed is high, and meanwhile it is beneficial to discharging of burning tail gas.

The invention relates to an energy-containing combustion-supporting catalyst which mainly is composed of the following components by weight: 25-28 parts of fusel oil, 14-18 parts of ethanol, 16-20 parts of tetralin, 14-16 parts of cyclopentanol, 18-22 parts of crotonic aldehyde, 1-2 parts of 2-pyrrolidone, 1.5-3 parts of nano rare earth oxide, and 2-3 parts of energy-containing cage-type boride or derivates of the boride. The energy-containing combustion-supporting catalyst can be applied to liquid or gas alkane fuel to form an energy-containing composite fuel so as to promote the thermal efficiency of the fuel, and can effectively replace acetylene to be used for metal flame welding cutting so as to improve the heat utilization rate of gas boilers and kilns. The energy-containing combustion-supporting catalyst is obvious in energy-saving efficiency, and saves fuel by more than 30 percent and saves oxygen by more than 20 percent in the process of metal flame welding cutting. Furthermore, compared with acetylene, the energy-containing combustion-supporting catalyst is safe in use, and is unlikely to cause tempering, and is safe and reliable in use.
