In the future, new air pollution control technologies will be required by coal-fired electric utilities and industrial boiler owners to meet more stringent environmental constraints. The CAIRE{trademark} (acronym for Controlled Air Emissions) combustor technology offers the benefit of reducing SO{sub 2} by some 70 to 90% and lowering NO{sub x} emission levels to 0.30 lb/10{sup 6} Btu or less, better than the best conventional low NO{sub x} burners on the market today. It also incorporates the advantage of a cyclone-fired unit by reducing particulate carryover into the boiler and downstream equipment by some 75 to 80%. This means that low cost, high sulfur and/or high ash coals may be fired in this combustor without the penalty of increased SO{sub 2} emissions, ash fouling and higher particulate stack emissions. The CAIRE{trademark} combustor may be retrofitted to electric utility boilers at a cost per ton of SO{sub 2} removed that is less than the price of SO{sub 2} allowance credits and less than the cost of switching from Eastern to Western US coal.
