Liquid fuel direct-fire heating device for supplementary heating hand-fired coal unit in e.g. premise, has blade displaced to hide opening and to suppress flame of combustion from fuel, and control unit to control displacement of blade
The device has an opening arranged on an upper part of a rectangular fuel tank (T) to form a hearth (FP) of the device. An extinguisher is placed on the upper part of the tank, and is formed by a removable blade (BL) that is displaced in a manner to hide the opening and to suppress flame of combustion from liquid fuel. An automatic control unit controls displacement of the blade. The unit has a driving servomotor (SM) coupled to the blade, and supplied with electric power by a battery (PS). A seismic detector (C3) of the unit detects the displacement of the blade.
