Liquid heating apparatus of the pulse combustion type

摘要

In a liquid heating apparatus of the pulse combustion type, a mounting plate is secured to a side wall of a liquid vessel for supporting thereon an air-fuel mixer head outside the vessel and a combustion chamber inside the vessel, and an inlet pipe is secured at its inner end to a front end wall of the combustion chamber and extended outwardly from the vessel through the mounting plate. The air-fuel mixer head is mounted to an outer end of the inlet pipe at a position spaced from the mounting plate, and the combustion chamber is supported by the inlet pipe at a position spaced from the mounting plate. During pulse combustion, the inlet pipe is cooled by the liquid flowing into the space between the front end wall of the combustion chamber and the mounting plate to protect the mixer head from the heat of high temperature transmitted thereto from the combustion chamber.
