Abstract
A burning stove includes a stove body, a front seat, a door, a rear seat, a top cover, and a baffle. The baffle divides the stove body into an air inlet chamber and a combustion chamber. The door is provided with first air inlet holes and second air inlet holes. The baffle is provided with first air holes. The baffle is provided with an air guide port and an air guide face. First partial air flows backward in the air inlet chamber, flows through the air guide port and the air guide face, and flows upward into the combustion chamber, and second partial air in the air inlet chamber flows through the first air holes into the combustion chamber. The first partial air and the second partial air form a vortex air flow in the combustion chamber.
