Heating is carried out in a furnace provided with coaxial tubes introducing into the firing chamber the flue and the air directed against a patching plate, the feeding of measured quantities of the fuel and air is performed discontinuously.

The furnace is preliminarily heated to a temp. above the ignition point. The use of a liquid hydrocarbon instead of coal dust used heretofor in furnaces of this type is an improvement, because there is no soiling of the fired articles with ash, and there is no need to introduce excess air.

Burner/boiler combination with an improved burner and combustion process

A compact burner/boiler combination (30) with a burner (10) is described. A liquid fuel (18) is gasified by the hot combustion products and forms a homogeneous fuel-gas/air mixture before combustion and leads to an essentially stoichiometric combustion of the fuel, thus resulting in a high speed and a very high flame temperature (approximately 4100 DEG F - 2100 DEG C); this leads to the splitting of some of the hydrocarbons into their basic elements, so that they are available for diffusive combustion. A small fraction of air is subsequently introduced tangentially (22) into the burner flame and generates the diffusive combustion of the free hydrogen and carbon produced by the combustion process and consequently a hot brilliant optimum flame formation with a high surface speed.
