Abstract

The invention discloses a furnace end lining structure for a combustion furnace of a sulfur recovery unit. The furnace end lining structure mainly comprises a furnace opening section lining structure,a straight barrel section lining structure and a transition section lining structure which is connected with a furnace opening section and a straight barrel section. The furnace opening section lining structure is sequentially provided with furnace opening section refractory bricks, furnace opening section insulating bricks and a furnace opening section castable layer from inside to outside. Thestraight barrel section lining structure is sequentially provided with straight barrel section refractory bricks, straight barrel section insulating bricks and a straight barrel section castable layerfrom inside to outside. The transition section lining structure is mainly formed by splicing a plurality of special-shaped refractory bricks. The furnace end lining structure is reasonable in designand high in firmness.

Description

technical field [0001] The invention relates to the field of sulfur recovery equipment, in particular to a lining structure of a combustion furnace head of a sulfur recovery device. Background technique [0002] The combustion furnace of the sulfur recovery unit is one of the core equipment of the sulfur recovery unit. The designed operating temperature of the combustion furnace is about 1450°C. The lining of the combustion furnace head of the traditional sulfur recovery unit generally adopts a castable structure or a simple brick structure. The material structure is easy to crack and peel off, and a large number of holes are concentrated in the furnace head, which makes the construction difficult; while the simple brick structure is easy to produce large expansion joints in the furnace head, causing the outer wall temperature to be too high or even burn through. [0003] Chinese patent CN203881138U discloses a refractory lining for the main combustion furnace of a sulfur re...
