Calculation method of the heat losses through the multi-layer solid-gas lining

Abstract

The furnaces' lining is the key component of their structure. It separates the furnaces' working chamber from the environment and reduces the irrecoverable heat losses. The brickwork cost and the heat losses through the brickwork can be reduced by means of the
using so called solid-gas lining which is the alternating solid layers and gas spaces. It is necessary that in the multi-layer monolithic linings the contact between the layers was ideal. The pores and gas spaces presence complicates the heat transfer inside the lining, and in turn, influences the heat loss from the furnace chamber. Ill. 2. Ref. 5
