Abstract

PURPOSE: To provide a low temperature ignition, restrict any incomplete combus tion and promote a low NOx by a method wherein an ultraviolet laser beam is radiated against methane gas fuels just before combustion to dissociate CH4 into CH2 and H2, respectively.
CONSTITUTION: Methane gas fuels from a fuel supply passage 1 and combustion air from a blower B are mixed with each other and sent to a mixture gas supply chamber 3 within a casing, mixture gas is supplied through an inner porous body 4 into an outer porous body 5 and then a surface combustion is carried out at a surface of the outer porous body 5. An ultraviolet laser from a laser oscillation device 7 is reflected at heat-resistant mirrors 8 and 9 oppositely arranged at a clearance 6 formed between both porous bodies 4 and 5, and the gas fuel of methane just before combustion, i.e. CH4 is dissociat ed into CH2 and H2 under an action of ultraviolet laser. That is, CH2 and H2 having more superior combustion characteristics than that of CH4 are surface ignited to realize the stable low temperature combustion, resulting in that a sufficient low NOx can be attained while any incomplete combustion or flame lift is being prevented.
