、ガス化燃焼が継続される。Further, air forced by a blower or the like is ejected into the vaporizer (1) from an air ejection nozzle (3). Then, the ejected fuel hits the inner wall of the carburetor (1), which has been preheated by the vaporization heater (2), and is vaporized. After being mixed with the combustion air, it is moved to the burner head (7) by the rectifying plate (6).
It is guided inside and ejects from the flame port (8). This mixed gas is then ignited by a spark discharge from a spark plug (not shown) and combusts. After the combustion starts, the combustion heat is recovered by the vaporizer (1), so even if the energization of the vaporization heater (2>) is stopped, the gasification combustion continues.

うにすることを目的とする。(c) Problems to be Solved by the Invention In the conventional device described above, the connection part (threaded part) between the air jet nozzle (3) and the vaporizer (1) is exposed inside the vaporizer (1), and the connection Since the pressure of the mixed gas in the vaporizer <1> is applied to the connection part, gas leakage has been prevented by applying a sealant to the connection part. However, if the sealant is insufficient, the sealant deteriorates due to heat, or the connections are not tightened sufficiently during assembly or service, the mixed gas inside the carburetor (1) However, due to the turbulent flow and changes in internal pressure, there were problems such as leakage from the connection part to the outside and emitting a bad odor.This invention was made in view of the above-mentioned facts.
The purpose is to easily and reliably prevent gas leakage from a vaporizer.
