A method for neutralizing or partial neutralization of the combustion of sulfur-containing heating materials in the case of the resulting acidic combustion products as well as means for the use in the exercise of the method

摘要

In the combustion zone of a furnace burning sulphur-containing fuel, one introduces continuously sodium or potassium nitrate; ammonium nitrate; calcium hydroxide and/or magnesium carbonate; carbon; and ammonium carbonate. Simultaneous injection of all of the above compounds is preferred, and a mixture thereof is claimed per se. A neutralization of acidic sulphur compounds formed by the combustion is achieved, and the boiler is kept free from soot and other deposits.
