METHOD AND BURNER ELEMENT FOR BURNING GAS BY VOID COMBUSTION SYSTEM

摘要

A method for burning a gas, characterized in that a pre−mixed gas is fed to a burner element which comprises laminated Si−C−M−O type continuous fibers containing, in atomic %, 30 to 60 % of Si, 30 to 70 % of carbon, not more than 5.0 % of M, and not more than 30 % of O, and has a void volume percentage of 60 to 98%, wherein M represents one or more metal elements selected from among alkali metals, alkaline earth metals, multi−valent metals, transition metals, noble metals, rare earth metals and actinide metals which form a stable oxide, carbide or silicide, and the pre−mixed gas undergoes void combustion directly under the surface of the burner element to thereby emit radiant heat; and a burner element for use in the method. The method can be advantageously used for carrying out radiant heating by means of a void combustion system using a liquefied petroleum gas, a liquefied natural gas, a city gas, or the like as a fuel.
