A high temperature combustion process for an organic fuel containing sulfur in which the nitrogen of air is replaced by carbon dioxide for combination with oxygen with the ratio of CO2/O2 being controlled to generate combustion temperatures above 2000 K. for a gas-gas reaction with SO2 and an alkali metal compound to produce a sulfate and in which a portion of the carbon-dioxide rich gas is recycled for mixing with oxygen and/or for injection as a cooling gas upstream from heating exchangers to limit fouling of the exchangers, with the remaining carbon-dioxide rich gas being available as a source of CO2 for oil recovery and other purposes.

A combustion process for an organic fuel comprising the steps of providing a combustion zone for burning a fuel with oxygen, introducing an organic fuel to a combustion zone, introducing a mixture of carbon dioxide and oxygen to the combustion zone to form a combustion gas, the mixture having essentially no nitrogen gas, providing heat exchanger means downstream from the combustion zone, introducing a carbon dioxide as a cooling gas into the combustion gas between the combustion zone and the heat exchanger means to reduce the temperature of the combustion gas to below about 1150K and from a cooled combustion gas, and, recycling a portion of the cooled combustion gas to be combined with oxygen for the combustion zone.
