Title: Liquid fuel burning device
Inventor: SATOU TADASHIGE
IPC: F23D3/04
Filed: 1979-02-13
Abstract: PURPOSE: To facilitate perfect combustion and expedite balancing of caloric force by airing a belt-like wick forcedly from both sides.  
     CONSTITUTION: When an adjusting shaft 23 is turned up to the ignition position by electrifying a motor 21, a wick 7 and a deflection plate 15 are raised and a flame lutlet 17a is widely opened, while the opening of dampers 20a and 20b being reversely drawn, thus a small quantity of air being supplied for an inner air-chamber  3 and an outer air chamber 10. Accordingly, ignition of the wick 7 makes flames immediately all around the periphery. Then, when the adjusting shaft 23 is turned back to the burning position, the wick 7 and the deflection plate 15 are lowered and the dampers 20a and 20b are opened, all to the desired degree, thus ring-like blue flames being formed. Flames are short and perfect combustion is attained because the air well spread and mixed is supplied before and after the flames pass through the flame outlet 17a. In addition, the flames strike only against a flame- regulating ring 17 and a part of the deflection plate 15 and so the rise of temperature is completed speedily, which brings about speedy balancing of the heating power.
