Combustion device for improved combustion efficiency

Abstract

A combustion device for improved combustion efficiency comprising a stove body and a burner. The stove body comprises a stove bowl and a stove shell. The stove shell includes a periphery with horizontal intake apertures that allow communication between the interior and exterior of the stove shell. The stove bowl defines a combustion zone and is surrounded by shielding components aligned with the intake apertures. Ventilation portions between adjacent shielding components connect the combustion zone to the interior of the stove shell, enhancing airflow. The burner comprises an arcuate first combustion pipe positioned within the combustion zone and aligned around a vertical centerline. This arrangement optimizes air and fuel mixing, aiming to improve combustion efficiency and overall heat distribution.
