Abstract

In the article, it is considered to establish the water-chemical regime on the DE 25/14 boiler, before starting alkaline washing with solutions of sodium hydroxide and sodium phosphate. The boiler washing procedure was carried out in five stages. After the end of flushing, the volume of flushing water was experimentally determined at various pressures. The article also describes how to establish the optimal mode of combustion of a mixture of gas and fuel oil in furnaces and performed heat engineering tests to determine the flow rate of ammonia when cleaning flue gases from sulfur oxide.
