Problems solved by technology

The traditional combustion furnace manhole lining is made of castables. The pouring process is not easy to tamp, which leads to problems in the compactness of the pouring lining, the structure is not firm, and it is prone to problems such as burning cracks or falling off, causing the furnace body to burst into flames. Acid production brings hidden dangers, and the manhole plug is too large, which is inconvenient to install or disassemble

Abstract

A combustion furnace manhole lining masonry structure includes a fireproof pouring layer, a heat insulation masonry layer, a lining fireproof masonry plug and an outer layer heat insulation manhole plug. The fireproof pouring layer is arranged on the inner side of a combustion furnace manhole, the heat insulation masonry layer is laid at the position of a combustion furnace manhole opening and isclosely attached to the fireproof pouring layer, the lining fireproof masonry plug fills a center hole of the fireproof pouring layer, and the outer layer heat insulation manhole plug fills a center hole of the heat insulation masonry layer. Compared with the prior art, the combustion furnace manhole lining masonry structure has the advantages that according to the combustion furnace manhole lining masonry structure and a masonry method, the integral structural stability of a manhole lining can be ensured, combustion furnace burnthrough accidents caused by lining hardening crack or flame out of a dropping furnace body are avoided, and the production running of an acid making system is stabilized.

Description

technical field [0001] The invention relates to the technical field of coking, in particular to a manhole lining masonry structure and a masonry method for a combustion furnace. Background technique [0002] Two combustion furnaces (one on and one on standby) in the acid production process of the coking department of a steel plant have been in operation for 7 years since they started operation in 2008, and they have been in service for overdue. At present, most of the lining bricks of the combustion furnace have cracks, which are very prone to burn-through accidents. In order to ensure the normal operation of the acid production system, the coking department organized the replacement of the lining refractories of the combustion furnace B in July 2015. [0003] Due to the combustion reaction of the combustion furnace, a large amount of heat is released, the furnace temperature is high, and there are various corrosive media such as H2S, SO2, SO3, etc. in the furnace. This put...
