ABSTRACT:
A method of desulfurizing carbonaceous fuel, such as coal and oil containing sulfur. The fuel is ignited in a boiler combustion zone and a saturated solution of potassium carbonate and potassium hydroxide is sprayed into the flue gas stream immediately downstream of the boiler combustion zone at a sufficiently high temperature to volatilize said sprayed solution to an ionic form. In the presence of excess oxygen at a temperature in excess of 1315.degree. C., the sprayed flue gas combines to form potassium sulfate particulates which are collected and removed dry, along with flyash particles, by mechanical or electrostatic precipitator equipment from the flue gas stream. The insoluble ash is separated from the soluble potassium sulfate by water elution. The solubilized potassium sulfate is separated by ion exchange mechanisms with the potassium, as potassium hydroxide, being recycled to the head of the system and the sulfate being reacted to form ammonium sulfate.
