This invention relates to combustion apparatus in which liquid fuel is used and more particularly to apparatus in which a liquid oxidizing agent such as liquid air or oxygen is also used. Such combinations of liquid fuel and liquid oxidizing agents are highly explosive and dangerous if not promptly and thoroughly ignited as soon as they are introduced into a combustion chamber. Such ignition is preferably provided in the form of a flame directed into the combustion chamber which contains the mixture of fuel and oxidizing agent. It is the general object of my invention to provide improved means for supplying an effective igniting flame for a combustion chamber. A further object is to provide improved means for maintaining an idle flame or hot point for lighting the igniting flame whenever the latter is desired for use. I also provide for a safe and predetermined order of operation of the several parts of the apparatus, to the end that danger may be effectively avoided.
