Alkali injection system with controlled CO/sub 2//O/sub 2/ ratios for combustion of coal [electronic resource]
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 CO/sub 2//O/sub 2/ being controlled to generate combustion temperatures above 2000/sup 0/K for a gas-gas reaction with...

| 520 | 3 | |a 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 CO/sub 2//O/sub 2/ being controlled to generate combustion temperatures above 2000/sup 0/K for a gas-gas reaction with SO/sub 2/ 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 CO/sub 2/ for oil recovery and other purposes. Several advantages are associated with the invention. First, by using a low CO/sub 2//O/sub 2/ ratio, higher flame temperatures can be achieved, thereby substantially promoting the gas-gas reaction between alkali atoms and sulfur gases. Second, by providing a means for injecting additional CO/sub 2/ at various locations removed from the combustion zone, the heat transfer rate and cooling of the alkali sulfates can be tightly controlled without suffering either the loss in efficiency inherent in conventional gas recycle techniques or the added cost associated with the larger mass throughput rate and heat transfer surface area. Third, there is the ability to use the concept in retrofit applications by tailoring the CO/sub 2/ quantity recycled to match the heat utilization performance previously achieved using air as the oxidizing medium. Fourth, a natural reduction in nitrous oxides is achieved by eliminating the reaction of oxygen with the nitrogen in the oxidizer. | |
