Problems solved by technology

In order to keep the quality of roasted products consistent, it is objectively required that the temperature of the furnace chamber of the side fire channel and the middle fire channel should also be kept basically the same, so it is necessary to increase the fuel input of the side fire channel to increase the furnace temperature of the furnace chamber near the side fire channel , which will increase fuel consumption and temperature adjustment difficulty accordingly

Abstract

The invention discloses a sidewall structure of a roasting furnace, which comprises a silicate plate layer and a refractory clay packing layer, wherein the silicate plate layer abuts against the furnace shell of the roasting furnace, the refractory clay packing layer abuts against the side flame path of the roasting furnace; and a silicate fiber layer and an insulating brick layer are orderly arranged between the silicate plate layer and the refractory clay packing layer. The invention discloses another sidewall structure of a roasting furnace, which comprises an insulating pouring material layer and a silicate fiber layer, wherein the insulating pouring material layer abuts against the furnace shell of the roasting furnace, the silicate fiber layer abuts against the side flame path of the roasting furnace, and a silicate plate layer and an insulating brick layer are orderly arranged between the insulating pouring material layer and the silicate fiber layer. The sidewall structure of the invention has the advantages of high strength, favorable insulating property, high universality, strong practicality and the like, and is convenient in construction.

Description

technical field [0001] The invention relates to a component structure of a furnace and a kiln, in particular to a component structure of a furnace lining part of a firing furnace. Background technique [0002] The existing roasting furnace includes the furnace shell (the furnace shell is generally a concrete retaining wall), the side wall and the furnace chamber in sequence from the outside to the inside. The furnace chamber near the side wall is provided with a side fire channel, and there are multiple side fire channels in the side fire channel. The middle fire path, in the middle of each fire path is a material box for placing roasted materials. [0003] In the existing roasting furnace, there is a gap of 1mm~2mm at the junction of the side flue and the side wall, because during the use of the roasting furnace, as the temperature of the furnace chamber rises, the flue wall will produce A certain amount of expansion, the gap is an expansion joint specially reserved for th...
