Upper-lower combination type dual-heat storage burner with embedded burner blocks

Abstract

The invention provides an upper-lower combination type dual-heat storage burner with embedded burner blocks, and belongs to the technical field of dual-heat storage burning on heating furnaces and heat treatment furnaces. The upper-lower combination type dual-heat storage burner comprises a shell body, an air heat storage box, a coal gas heat storage box, the coal nozzle burner block and an air nozzle burner block; the air heat storage box and the coal gas heat storage box are combined in the shell body and are in an upper-lower structure. The embedded coal nozzle burner block and the embedded air nozzle burner block 18 are designed to be of a boss structure. When being installed on a burner body, the burner blocks are inserted into the burner body by 70 mm; when the burner blocks are mounted, a 10-mm zirconium-containing fiber blanket is wrapped around each burner block and extruded to be 5 mm thick, so that a compact fiber sealing surface is formed. The upper-lower combination type dual-heat storage burner with the embedded burner blocks has the advantages that the embedded burner blocks are of the boss structure and are connected with the burner body through drag hooks, the gaps between the burner blocks and the burner body are filled with the 10-mm zirconium-containing fiber blankets, and therefore the burner blocks and the burner body are more reliably connected; the burner is light in structure and convenient to install and maintain.

Description

Technical field [0001] The invention belongs to the technical field of combustion on heating furnaces and heat treatment furnaces. In particular, it relates to a dual heat storage burner with embedded upper and lower combination of burner bricks. Background technique [0002] In the design and installation of the traditional double regenerative burner, the end face of the burner brick is fixed at the front end of the double regenerative burner body, flush with the refractory castable of the furnace wall, and the refractory material is poured around the burner brick, because the burner brick is relatively large , Only one row of anchor bricks can be set between the burner bricks. Considering that the refractory castable of the furnace wall expands at high temperature, it is necessary to set a 6-10mm expansion joint between the burner bricks. Due to the partition effect of the expansion joint, The anchor bricks fixed on the steel plate of the furnace wall cannot play the role of p...
