中日文在线翻译摘要：PURPOSE:To prevent backfire and make it possible to give surface combustion always in stable state by providing a porous metal piece through which a premixing gas pasd at the downstream side of a mixing chamber where the premixing gas is made and mounting a cooling pipe through which a cooling fluid pass and which cools the porous metal piece. CONSTITUTION:A porous metal piece 10 which is made of a sintered metal and so on is provided on the downstream side of a mixing chamber 9, and a cooling pipe 11 is fixed on to this porous metal piece 10. The porous metal piece 10 is cooled by a cooling pipe 11 through which a cooling fluid pass to maintain the temperature of a premixing gas which is passing through the small holes in the porous metal piece at a temperature below the ignition temperature. When in order to lower the combustion temperature of a burner A the amount of the premixing gas is reduced and its supply speed is lowered, the position of the ignition that is made in the combustion chamber 12 is apt to move gradually towards the mixing chamber 9, but since the premixing gas that is passing through the porous metal piece 10 is maintained at a temperature below the ignition temperature, it does not ignite. Accordingly there is no fear that backfire occurs
