PORTABLE TYPE HOT AIR HEATER

摘要: PURPOSE:To shorten a combustion rise time at ignition and enable variation in air temperature caused by an excessive or insufficient of amount volume to be adjusted method wherein mixing ratio adjusting means for freely changing fuel gas supplied device is arranged. CONSTITUTION:At time, opening 43 opened maximum injected into 2 through nozzle 34 enters catalyst 25 so as start the combustion. Almost all fed blower 1 passed supply air. little bit only from suction port 26 2, resulting richer concentration, quickly expanding short time. After has progressed, 143 decreased increase 26, then remaining heated finally delivered discharging cover 21. When capacity cell 4 varies, degree varied hot also controlled.
