Abstract
A combustion apparatus 2 has an anti-spreading member 65 disposed below a combustion chamber 10. This anti-spreading member 65 is composed of a generally cylindrical main body 65a, an outer flange 65b and an inner flange 65c, these flanges being formed at and integral with the opposite ends of the main body 65a, respectively. A controller 40 for regulating the operation of this apparatus 2 is designed to preheat the anti-spreading member 65 at a heat generation rate ‘q’ lower than the required heat generation rate ‘Q’, before the apparatus starts its normal operation to burn a fuel.
Claims22
A combustion apparatus comprising:
- a spraying means for spraying a fuel to form a fuel mist stream,
- a combustion chamber designed to burn therein the fuel mist stream to form a flame,
- a fuel channel through which the fuel flows, and
- an anti-spreading means disposed at a downstream region of the combustion chamber so as to inhibit the fuel mist stream and the flame from freely spreading radially and outwardly out of the downstream region,
- wherein the anti-spreading means is capable of being preheated prior to combustion carried out in the combustion apparatus,
- wherein the anti-spreading means has a downstream end and near its downstream end a gas-staying member with a radially extending wall in which a constricted outlet opening is defined.
