A kiln including a stove and a heat source wherein the stove includes a chamber, an air guide structure, an exhaust pipe and a heat storage member. The chamber includes a cavity, an entry, and an air outlet. The air outlet is located between a top of the front section of the cavity and the entry. The air guide structure communicates with the air outlet and includes a guide plate. The exhaust pipe is disposed above the guide plate, and an exhaust channel is formed by the guide plate of the air guide structure and the exhaust pipe. The heat storage member covers an exterior of the cavity which is corresponding to the top of the front section of the cavity, and contacts the air guide structure. The heat source is disposed in the stove and adapted to heat the cavity.

Cooking apparatus comprises an oven. The oven comprises a cooking chamber, a heated air source and two or more vents through which, in use, heated air can vent from the cooking chamber. The two or more vents comprise at least one lower vent and at least one upper vent. The at least one lower vent is provided at a lower height than the at least one upper vent. The at least one upper vent is controllable to regulate a flow of heated air therethrough.

A portable stove for burning biomass fuels. The stove has an outer body with walls coupled together with hinges and an opening to load fuel into the stove. The stove further includes a combustion chamber with walls coupled together with hinges that fits within the outer body. The combustion chamber has an opening for loading fuel, secondary openings along upper portions of the walls, a floor with openings to permit airflow into the chamber, and upright posts along the walls to support a cooking utensil for heating. The stove also has a dam that rests on the top of the combustion chamber to direct air through the secondary openings and into the combustion chamber to improve the burning of fuel. The outer body and combustion chamber hinges permit the stove to fold for better storage and transport.

Combustion apparatus for use with a solid fuel has a firebox constructed at least in part of a fired refractory carbide material. The fired refractory carbide material has a catalytic effect on the combustion process providing a cleaner and more efficient combustion. The fired refractory material also absorbs heat from the combustion process directly or indirectly by heat exchange with combustion products and dissipates the absorbed heat over an extended period of time providing space heating after the combustion process is completed.
