Abstract
The utility model relates to a measuring device for swirl vane angles of a combustor. The measuring device comprises a long sliding pole, a casing pipe and an angle meter, wherein the casing pipe sleeved on the long sliding pole is fixedly connected with a short sliding pile, and the angle meter is arranged at the top end of the short sliding pole. The measuring device is simple in structure, convenient in operation and accurate in measuring results. When using the measuring device, an operator can measure the angles only by erecting a simple scaffold without climbing into the combustor for measurement. The measuring device without complicated supporting equipment not only ensures safety of the operator, but also improves work environments.
Description
Technical field
The utility model relates to a kind of measurement mechanism of burner swirl vane angle.
Background technology
The fuel-burning power plant that acts as a fuel with fire coal is that electrical network and economic development provide the most energy, the front-back wall opposed firing is a kind of widely combustion system of large-size thermal power plant boiler applications, and the secondary air blade angle in its major equipment turbulent burner has very big influence to aerodynamic field and combustion position.In capital construction and test, measure comparatively difficulty of blade angle, error is bigger, is subjected to interference from human factor bigger.At present too simple to the measurement of blade angle, only to crawl into burner and measure along burner blades with common side angle device and ruler, working environment is dangerous and abominable, and error is at least 5 °.The deviation of blade angle tends to influence the aerodynamic characteristics of burner, and fire coal can not stabilizing effective after-flame, and boiler thermal output reduces, even influences the station boiler safe and stable operation.
The utility model content
Technical problem to be solved in the utility model provides a kind of measurement mechanism of measuring burner swirl vane angle accurate, easy to operate, applied widely.
The utility model adopts following technical scheme:
The utility model comprises long litter, is sleeved on the clinometer rule that is fixedly connected with the sleeve pipe of short litter and is arranged on short litter top on the long litter.
The short litter of the utility model is to be made of two sleeve pipes.
Good effect of the present utility model is as follows:
The utility model is simple in structure, and is easy to operate, and measurement result is accurate.In use do not need operating personnel to crawl in the burner and measure, only need in burner hearth, to set up simple framing scaffold and get final product, do not need complicated support equipment, both guaranteed operating personnel's safety, improved working environment again.The accurate measurement result of the utility model can guarantee the installation quality of combustion apparatus in the capital construction, improves installation accuracy, also can be boiler tests such as burning adjustment, aerodynamic field measurement result accurately is provided, and for analysis, has enriched measurement means.
The measurement mechanism of the utility model burner swirl vane angle has the scope of application widely on the station boiler that uses turbulent burner, from burner capital construction adjusting of initial stage blade angle is installed, the inspection of blade angle all has application in the boiler cold-state test.
Description of drawings
Accompanying drawing is the utility model structural representation.
In the accompanying drawings: 1 long litter, 2 short litter, 3 side angle devices, 4 sleeve pipes.
Embodiment
As shown in drawings, the utility model comprises long litter 1, is sleeved on the clinometer rule 3 that is fixedly connected with the sleeve pipe 4 of short litter 2 and is arranged on short litter 2 tops on the long litter 1.The long litter 1 of the utility model is provided with sleeve pipe 4, and sleeve pipe 4 is connected on the short litter 2, and long litter 1 can be fixed in burner hearth internal combustion spout place, by the sleeve pipe on the moving long litter 14, changes the position of short litter 2.Short litter 2 is to be made of two sleeve pipes, can stretch and rotate weak point litter 2 and will lack the position that the clinometer rule 3 on litter 2 tops reaches burner secondary air blade angle, opens side angle device two arm measure burner angles.After measurement finishes, regain this device, read blade angle.The utility model is simple in structure, and is easy to operate, and measurement result is accurate.In use do not need operating personnel to crawl in the burner and measure, only need in burner hearth, to set up simple framing scaffold and get final product, do not need complicated support equipment, both guaranteed operating personnel's safety, improved working environment again.The accurate measurement result of the utility model can guarantee the installation quality of combustion apparatus in the capital construction, improves installation accuracy, also can be boiler tests such as burning adjustment, aerodynamic field measurement result accurately is provided, and for analysis, has enriched measurement means.
