PROBLEM TO BE SOLVED: To facilitate replacement of a burner head in a site and improve maintainability by enabling a burner head a having combustion blower, a fuel pump, a fuel-jetting nozzle, an ignition plug and an igniter incorporated therein to be installed in a combustion chamber with a coupling by one touch operation. SOLUTION: A hot blast generator suitable for a rail point snow-melting system for railroad has a blower 2 rotated by an AC motor 1 disposed in the front portion of an outer housing 6 to supply air passing between the outer housing 6, the burner head 4 and combustion chamber 5 by its revolution. In this case, the burner head 4 has a unit constitution in which a DC motor 7, a hall sensor 9, a fuel pump 10, a nozzle 11, an igniter 12, a plug 13, a flame sensor 14 and the like are integrally assembled, and is detachably attached to the combustion chamber 5 through a V band coupling 17 by one touch operation. |
