<p>PURPOSE:To prevent accumulation of high boiling point constituents in fuel in a vaporizer by automatically controlling the number of supply ports of heat conveying pipe so as to adjust the amount of the petroleum gas which is introduced into the vaporizer installed downstream of a pre-heater. CONSTITUTION:The fuel having propane as the primary constituent and heated by a pre-heater 1 is supplied to a vaporizer 25 through adjusting valves 5a, 5b etc. The fuel is heated and vaporized by heating source introduced through an adjusting valve 6 while it flows in heat conveying pipes 23a, 23b, and is supplied to a burning apparatus through a conduit 15. As the adjusting valve automatically opens supply ports 22a, 22b etc. in a number corresponding to the demand by processing the vaporization demand signal from the fuel consumption side by a distributor 24, high boiling point constituents are prevented from accumulating in the vaporizer 25 without being vaporized.</p> |
