Abstract
A kind of boiler cold-state test special stand, including anemobiagraph, body, pipe joint and fixed support.Described fixed support right angle setting is fixed in boiler；Being perpendicular to support bracket fastened horizontal plane, four bodys are in 90 and are arranged on fixed support；Described body is made up of fine steel tube and pipe joint, is connected along tube length direction fine steel tube by pipe joint, and on body, each joint fine steel tube length is equal, and often saves on fine steel tube equipped with an anemobiagraph.On body, each pipe joint can be dismounted by pipe joint, thus realizes the length of telescoping tube, it is simple to tests various sizes of burner hearth.This utility model easy to use and flexible, highly versatile, testing crew just makes different supports without every new power plant.
Description
Technical field
This utility model relates to a kind of boiler cold-state test special stand, belongs to boiler exam technical field.
Background technology
Station boiler is and one of the most important equipment of thermal power generation, and it is safe and stable, reliability service is the important leverage that electric power safety produces.Combustion Operation of Boilers largely affects boiler plant and the economy of whole power-plant operation and safety, put into operation at new-built unit, major overhaul or in repair, the link such as boiler combustion system transformation, for finding out its combustion conditions, need to carry out boiler cold-state ventilation experiment, being even more important pulverized-coal fired boiler, " boiler startup debugging directive/guide " 4.3.1 clearly proposes cold conditions ventilation experiment content and standard.The reliability of boiler operatiopn and economy depend greatly on the operation conditions of the pneumatic condition furnace in burner and burner hearth, i.e. air and combustion product.Can be the best with phenomenons such as the distribution of macroscopic examination gas stream in the stove, diffusion, disturbance, mixing by cold conditions ventilation experiment；When the combustion conditions in stove is abnormal, cold test can help to analyze and discovering device installation and operation problem, and the improvement for equipment and the method for operation provides scientific basis, it is to avoid affects unit safety operation accident and occurs.
Before cold test stove build-in test, point layout is one of indispensable test link, in stove, the specification of point layout support need to change according to the change of required test size of burner hearth, so every new power plant all needs to make different point layout supports in the face of new boiler test personnel, different support reinstalls anemobiagraph again, and this just adds the biggest workload to testing crew.
Summary of the invention
The purpose of this utility model is, according to existing power station boiler cold tests point layout present situation, the utility model proposes a kind of boiler cold-state test special stand.
The technical solution of the utility model is, this utility model one boiler cold-state test point layout special stand, including anemobiagraph, body, pipe joint and fixed support.Described fixed support right angle setting is fixed in boiler；Being perpendicular to support bracket fastened horizontal plane, four bodys are the most in 90 ° to be arranged on fixed support；Described body is made up of many fine steel tubes and pipe joint, is connected along tube length direction fine steel tube by pipe joint, and on body, each joint fine steel tube length is equal, and often saves on fine steel tube equipped with an anemobiagraph.
On described body, each joint fine steel tube can be dismounted by pipe joint, thus realizes the length of telescoping tube, it is simple to tests various sizes of burner hearth.
This utility model easy to use and flexible, highly versatile, testing crew just makes different supports without every new power plant.
This utility model is applicable to boiler cold-state test.
Accompanying drawing explanation
Fig. 1 is that this utility model boiler cold-state tests special stand structural representation；
In figure, 1 is anemobiagraph；2 is pipe joint；3 is fixed support；4 is body；
Detailed description of the invention
Detailed description of the invention of the present utility model is as shown in Figure 1.
The present embodiment is achieved like this, and the present embodiment boiler cold-state test special stand includes that anemobiagraph 1, pipe joint 2, fixed support 3 and body 4 form.
The present embodiment middle tube body is made up of many fine steel tubes and pipe joint, and body 4 is sequentially connected with fine steel tube by pipe joint 2 along its length, and on body, each joint fine steel tube length is equal, and often saves on fine steel tube equipped with an anemobiagraph 1；On body, each joint fine steel tube can be dismounted by pipe joint 2, thus realizes the length of telescoping tube, it is simple to tests various sizes of burner hearth.
This utility model easy to use and flexible, highly versatile, testing crew just makes different supports without every new power plant.
