Abstract:
A heating apparatus for generating and transferring heat to a heat sink comprising:a tubular combustion chamber for combusting a fuel therein, thereby generating heat, the combustion chamber comprising a lower portion provided with a bottom surface, and an open upper portion; air injecting means coupled to the combustion chamber for injecting air therein while the fuel is combusting, the air injecting means being coupled to the combustion chamber in a manner such that upon injection of air, a first flow of air substantially swirls towards the upper portion of the combustion chamber and a second flow of air flows substantially parallel to an inner wall of the tubular combustion chamber towards the upper portion whereby the heat is transferred to the heat sink in intimate contact with the combustion chamber; the combustion chamber is disposed over the air injecting means, and said air injecting means is comprised of a series of air injectors extending from an air inlet chamber into the combustion chamber.
