Combined highly-resistant lining of the furnace chambers for the feeding yeast suspension drying

Abstract

The lining service conditions of the furnace chamber SRTs12,5/1500NK at Mozyrskii feed yeast Plant are investigated in the article, as well as the character of its destruction and the combustion process are studied. The refractory adhesive was engineered and tested to use it as the brickwork mortar. The furnace lining's refractories treatment with the aluminum-chromium-phosphate binder having the reasonable density allowed to reduce the refractories porosity and thus to increase their strength by 30 %, and to rise their heat stability as much as three times. The highlyresistant mullite-corundum refractories lining based on the fused materials was tested, the «chess grid» brickwork was upgraded, the protective highly-resistant coating was used for the local breaking outs repairing. As the result of these measures application the furnace chamber's lining resistance was increased by the factor of 2,5‒3,0, namely from 2‒3 to 9‒10 months. Ill. 5. Ref. 5. Tab. 2.
