Embodiment

[0038]Take the burner required for a 140KW external single regenerative radiant tube burner as an example.

[0039] Its form is as figure 1 shown.

[0040] Such as figure 2 and image 3 As shown, the burner cavity 1 includes a large anchor hook 11, a cavity weldment 12, a fiber blanket 13, a bolt 14, a small anchor hook 15 of the burner cavity, a lightweight castable layer 16, and an L-shaped half-through groove 17 And the recess 18, the burner brick 2 includes an L-shaped connector 21, a sleeve 22, a small anchor hook 23 of the burner brick, and a heavy castable layer 24.

[0041] Such as figure 2 , 3 As shown, the cavity weldment 12 is welded by heat-resistant steel according to the drawings. The large anchor hook 11 and the small anchor hook 15 of the burner cavity are welded with the cavity weldment 12 . The fiber blanket 13 is laid on the inner wall of the cavity welding part 12 . The bolt 14 is sealed and welded with the cavity weldment 12 . The lightweight ca...

Abstract

The invention relates to a replaceable burner brick for a regenerative radiant tube burner, which comprises a burner cavity and a burner brick. The burner cavity has at least one card slot. The burner brick has at least one hook. The burner cavity and the burner bricks are connected through the slot and the hook. The burner provided by the invention adopts the slot type installation form instead of bolt connection, which saves radial space, does not affect the installation of the radiant tube burner, and avoids the defect that the bolt cannot be replaced due to deformation at high temperature.

Description

technical field [0001] The present invention generally relates to a regenerative radiant tube burner, and in particular to a burner for a regenerative radiant tube burner. Background technique [0002] The regenerative radiant tube burner applies high-temperature air combustion technology to the gas radiant tube. It mainly uses gas as fuel and burns in a special sealed sleeve, and transfers heat to the burner in the form of thermal radiation through the heated sleeve surface. The object to be heated uses the sensible heat of combustion flue gas in the tube to preheat the combustion-supporting air or gas through the arrangement of the regenerator, and realizes stable combustion under the conditions of high preheating temperature air or gas and low oxygen concentration. Regenerative radiant tube burners have the characteristics of high combustion thermal efficiency, stable operation and high equipment reliability, and are widely used in various heat treatment furnaces and cont...
