Abstract
The utility model proposes high reliability DC burner spouts.DC burner spout leading portion together with laminated steel square tubes soldering, is assembled together using dovetail mosaic texture between wear-resistant ceramic layer and laminated steel square tube by steel alloy square tube, combustion stabilizing body is installed in DC burner.The utility model is indeformable after DC burner spout can be made heated, is able to maintain enough rigidity, has certain elasticity, can be improved the mechanical strength of spout.It can guarantee that wear-resistant ceramic is not fallen off.It is suitable for being used as boiler-burner spout.
Description
Technical field
The utility model relates to a kind of DC burner spouts, and in particular to high reliability DC burner spout.
Background technique
DC burner in boiler is tissue furnace combustion process and the main component for forming Furnace Aerodynamic Field.Its
Nozzle position is subjected to frequent thermal shock, and the radiation temperature from burner hearth is at 1000 DEG C or more, former nozzle be 310S or
The square spout of Cr50Ni50 material, temperature distortion is big, causes the anti-wearing ceramic material breaks inlayed to fall off, loses the office of scuff-resistant coating
Portion is worn quickly, so that spout flame deflects, is caused water-cooling wall damage and other accident, is forced blowing out.
To solve the above problems, proposing a kind of high reliability DC burner spout, clad steel plate (stacked steel plate) is by more
Layer sheet metal is laminated, and is outsourced steel plate and is included in.
Utility model content
In order to overcome disadvantage of the existing technology, the utility model provides high reliability DC burner spout.It should
Spout constitutes spout by steel alloy square tube and stacking square tubes soldering, and wear-resistant ceramic layer is inlaid in spout, solves direct current combustion
The technical issues of burner notch setting.
The utility model solves scheme used by technical problem:
DC burner spout leading portion by steel alloy square tube together with laminated steel square tubes soldering, wear-resistant ceramic layer and stacking
It is assembled together between steel square tube using dovetail mosaic texture, combustion stabilizing body is installed in DC burner.
Good effect: the utility model is indeformable after DC burner spout can be made heated, is able to maintain enough rigid
Degree has certain elasticity, can be improved the mechanical strength of spout.It can guarantee that wear-resistant ceramic is not fallen off.It is suitable for as boiler
Burner nozzle uses.
Detailed description of the invention
Fig. 1 is the utility model DC burner outline drawing；
Fig. 2 is the utility model side view；
Fig. 3 is the utility model Section A-A cross-sectional view.
In figure: 0. DC burner, 1. wear-resistant ceramic layers, 2. laminated steel square tubes, 3. steel alloy square tubes.
Specific embodiment
According to the figure, 0 spout leading portion of DC burner is welded together by steel alloy square tube 3 and laminated steel square tube 2, wear-resisting
It is assembled together between ceramic layer 1 and laminated steel square tube 2 using dovetail mosaic texture, combustion stabilizing body is installed in DC burner.
The combustion stabilizing body is the structural body for stablizing burning, including gas nozzle and flow distribution plate.
The laminated steel square tube peripheral direction is equipped with unidirectional free wxpansion space, and stacking steel disc free end is evenly arranged on stacking
Steel square tube periphery.
The burner nozzle is made of stacking steel disc.
Feature:
Wear-resistant ceramic can wear-resisting, high temperature resistant and have good thermal shock resistance.Wear-resistant ceramic is removed with laminated steel square tube
Using outside dovetail mosaic texture form, there are the expansion clearance of design flow, filled between expansion clearance using refractory mortar.
DC burner spout, it is indeformable after spout made of laminated steel square tube is heated by improving structure design.It can
Enough rigidity is kept, there is certain elasticity, can be improved the mechanical strength of integral plate.It can guarantee that wear-resistant ceramic does not take off
It falls.To improve DC burner spout overall stability and service life.
The DC burner spout being made of the structure, stable structure, therefore there is high reliability.
Claims (2)
1. high reliability DC burner spout, it is characterized in that: DC burner (0) spout leading portion by steel alloy square tube (3) with
Laminated steel square tube (2) welds together, and is assemblied in one using dovetail mosaic texture between wear-resistant ceramic layer (1) and laminated steel square tube
It rises, combustion stabilizing body (4) is installed in DC burner.
2. high reliability DC burner spout according to claim 1, it is characterized in that: laminated steel square tube periphery side
