Abstract

Abstract The research purpose of the work is to extend the service life by experimental study of the performance of the liquid-layer furnace. Here, instead of large and small aggregates, the effect of the use of secondary refractory substances in reducing the cost of the concrete mixture is studied. The value of the study is to prove that heat-resistant concrete meets the technological requirements of a liquid-layer furnace, as well as experimental confirmation of the possibility of using secondary refractory materials as heat-resistant concrete aggregates. To solve this problem, it was proposed to replace the traditional method of facing the boiling floor furnaces (Fireclay brick of the SHB brand) with a monolithic concrete version. Considering that the technological feature of the boiling layer of the furnace is a high temperature up to 1000°C and an aggressive environment that causes SO3 gaseous sulfur, one of the well-known types of heat-resistant concretes, the sodium-infused liquid glass concrete type is selected as the base, and instead of cement, it is recommended to use liquid glass with low thermal conductivity, such as a material in the amorphous phase and a glass-layered composite viscous substance.
