PURPOSE:To enable LNG to be used as liquid fuel, by a method wherein a burner is formed with a liquid injection nozzle, a primary gas/injection nozzle, and a secondary gas/nozzle, and a flame stabilizing cylinder is situated on the downstream side. CONSTITUTION:If LNG is fed through a conduit 4 to a liquid injection nozzle 1, it is injected at high speed. Primary air is introduced through a feed pipe 5 to a primary gas/injection nozzle 2, and the LNG is mixed with primary air in a premixing chamber (a). In this case, the LNG is crushed by friction with air to produce a spray flow. In this case, an LNG streamline is reduced by primary air and is injected in a secondary gas/injection nozzle 3. After the LNG is mixed with secondary air, fed through a feed pipe 6, in a secondary mixing chamber (c), the mixture is ignited by a pilot burner 7. Flame is held in a high density state by means of a flame stabilizing cylinder 8. This constitution enables the LNG to be used as liquid fuel.
