PURPOSE:To provide a combusting equipment wherein open spaces, parts, and elements in its outer case can be cooled effectively and from which the noise discharged to the outside is reduced. CONSTITUTION:A combustion equipment of the forced air-intake/discharge type has at least a combustion shell and a burner 3 inside its outer casing 1 and is equipped with a forced air-intake passage of closed circuit type by which a suction fan 7 forcedly takes in outside air through an intake pipe 4 and sends it through a fan case 5 to a burner 3. In the fan case 5 an air- ejecting hole 13 is formed, through which air is ejected into the space inside the outer casing 1. |
