Patent ID: 7758336

Claim:
A process for the combustion of a liquid fuel and an oxygenated gas in a combustion zone comprising the steps of: a) heating a solid fuel until the solid fuel is liquefied and heating the resultant liquid fuel until the liquid fuel has a desired viscosity of at least 30×10 −6 m 2 /s, b) injecting the liquid fuel at the desired viscosity as a stream into the combustion zone, c) injecting an atomizing fluid as a stream into the combustion zone, d) bringing the stream of liquid fuel into contact with the stream of atomizing fluid only in the combustion zone, e) injecting oxygenated gas into the combustion zone by at least one primary oxidizing jet near the atomized liquid fuel so as to bring about a first combustion yielding first combustion products comprising at least some uncombusted fuel, and f) injecting oxygenated gas into the combustion zone by at least one secondary oxidizing jet at a distance l 2 from the atomized fuel which is greater than the distance l 1 between the atomized fuel and the primary oxidizing jet, so as to enter into combustion with at least part of the uncombusted fuel from the first combustion products.
