Abstract
The utility model provides a durable burner nozzle, includes the combustor spray tube, and combustor spray tube centre bore is the oil spout passageway, and the oil spout passageway outwards is whirl wind channel, buggy wind channel, outer axle wind wind channel in proper order, is referred to as each layer wind channel of burner nozzle, and burner tip, screw thread correspond connects the corresponding pipeline in each layer of combustor. The material of each layer pipe wall of burner tip is exotic material, pipeline that each layer of combustor set up the screw thread for the welding at the one section exotic material pipeline that corresponds layer pipeline. The shower nozzle uses exotic material, the fire -resistant high temperature material of shower nozzle thread tightening, and welded exotic material pipeline and exotic material shower nozzle threaded connection are passed through to the combustor wind channel for the exotic material shower nozzle can be changed, and makes whole nozzle life longer.
Description
Technical field
The utility model relates to burner arts, particularly relates to a kind of durable burner nozzle.
Background technology
In traditional cement production process process, mostly with common, simple single air channel, two air-channel coal powder combustor, the burner of these kinds, black duration and degree of heating is long, efficiency of combustion is low, and flame profile and temperature cannot regulable control, are difficult to the national conditions of applicable coal resources in China.
At the beginning of the eighties, China has introduced Three-channel Coal Burner, and has in succession carried out secondary development, substantially overcomes single air channel, the defect that two air-channel coal powder combustor exists, but this burner structure is complicated, expensive.
Now, burner comprises four layers of passage, and burner structure is complicated, and profile is huge, and during making, material requested is huge.Due to burner tip and main body one, during making, whole burner uses commaterial, and will go deep in combustion furnace due to burner head, whole in combustion furnace is hot environment, if use exotic material, then cost is high, as used non-high-temperature resistant material, fragile under high temperature, then service life is short, constantly will change burner, final average unit cost is high.
Utility model content
In order to overcome the above problems, the burner nozzle that the utility model provides a kind of high temperature resistant, shower nozzle detachably to change.
Specific embodiments of the present utility model is: a kind of durable burner nozzle, comprise combustor nozzle, combustor nozzle centre bore is fuel injection passage, fuel injection passage is outwards followed successively by swirl air duct, coal dust air channel, outer shaft wind air channel, be referred to as each layer air channel of burner nozzle, every layer of air channel is made up of the gap between two-layer tube wall, and the end of combustor nozzle is shower nozzle, each layer burner tip one end is spout, and the other end establishes screw thread correspondence to connect the corresponding pipeline of each layer of burner.
The material of each layer tube wall of burner tip is exotic material.
The pipeline that each layer of described burner arranges screw thread is the one section of exotic material pipeline being welded on respective layer pipeline.
The beneficial effects of the utility model: shower nozzle uses exotic material, shower nozzle screw thread fixes fire-resistant high-temperature material, burner air channel is threaded with exotic material shower nozzle by the exotic material pipeline of welding, exotic material shower nozzle can be changed, and make whole nozzle longer service life.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Fig. 2 is sectional view of the present utility model.
Detailed description of the invention
As shown in Figure 1 and Figure 2, a kind of durable burner nozzle, comprises combustor nozzle 8, and combustor nozzle centre bore is fuel injection passage 2, and fuel injection passage is outwards followed successively by swirl air duct 3, coal dust air channel 4, outer shaft wind air channel 5, is referred to as each layer air channel of burner nozzle.Each layer air channel of burner nozzle respectively by adjacent channel tube wall between space form, the end of combustor nozzle is shower nozzle 1, and each layer burner tip 1 one end is spout 10, and the other end establishes screw thread 9 correspondence to connect the corresponding pipeline of each layer of burner.
The material of burner tip 1 each layer of tube wall is exotic material.
The pipeline that each layer of described burner arranges screw thread 9 is the one section exotic material pipeline of welding 7 at respective layer pipeline.
Burner tip 1 is fixed with the corresponding screw thread of burner each layer pipeline, is convenient to the replacing of burner tip 1, is the longer service life of whole burner, average unit cost height.
Burner tip outermost layer 1 is for holding together flame cover 6, and Constrained flame is a scope, and the effect in pilot flame direction, holds together flame cover 6 and use refractory material.
