AI Technical Summary
When there is a power outage or no power supply, the existing wood-burning stoves cannot allow outside air to enter the combustion chamber, which affects the efficiency of wood combustion and causes serious ash accumulation problems.
A wood-fired boiler head was designed, comprising a combustion chamber, a burner head, a feed inlet, an air inlet pipe, a support frame, and support bars. When powered by a blower, air is forced to be delivered. When power is off, natural ventilation is achieved through the gap between the support frame and the mounting frame to ensure air circulation, and ash accumulation is reduced through the gaps in the support bars.
It can still ensure the combustion efficiency of firewood in the event of a power outage or in the absence of electricity, and reduce ash accumulation in the combustion chamber, thereby improving combustion stability and efficiency.
