Abstract

Service conditions for the lining of SRTs12.5/1500 NK furnace chamber in the Mozyr’ Nutritional Yeast Plant (MZKI), the nature of its breakdown, and combustion processes are studied. A refractory adhesive is developed and tested as a brickwork mortar. Use for impregnation of a furnace refractory lining of an aluminium-chromium phosphate binder of optimum density makes it possible to reduce refractory porosity and thereby increase strength by 30%, and thermal shock resistance by a factor of three. Alining of highly resistant mullite-corundum refractory based on fuzed materials is tested: a “chequerboard” furnace brickwork scheme is accomplished; a protective highly-resistant coating is used for repairing local breakage. As a result of introducing these measures combustion chamber lining life is increased by a factor of 2.5 – 3.0, i.e., from 2 – 3 to 9 – 10 months.
