Abstract
The utility model provides a 600 MW overcritical W flame boiler combustor spout tube panel device. The oercritical W flame boiler waterwall pipe pitch, tube diameter are both small, the tube rigidity is poor, and the sealing demand of the tube panel is high, thus the structure of the combustor spout tube panel is complicated. The 600 MW overcritical W flame boiler combustor spout tube panel device of the utility model comprises: a water screen tube panel (1), and a hanger (2). The water screens adopt the structure of the membrane wall vertical tube loop, and the combustor is arranged on the top of the protruding arch at the front and rear water screens; the water screen tube panel is welded to a combustor spout tube panel (3), the hanger (2) passes through the combustor spout tube panel (3) including a set of horizontally arranged tubes (4), and the tubes are connected by steel plates or steel flats (5). The 600 MW overcritical W flame boiler combustor spout tube panel device of the utility model is used for the overcritical boiler W flame combustor external structure.
Description
Technical field:
the utility model relates to a kind of novel jet pipe screen device, is specifically related to the overcritical W flame boiler of a kind of 600MW burner nozzle tube panel device.
Background technology:
breathe out at present pot use anthracitic W flame boiler be subcritical, thereby the low power plant's operational efficiency that causes of steam parameter is low.According to national Eleventh Five-Year Plan ENERGY PLANNING and industry restructuring and energy-saving and cost-reducing requirement, exploitation high parameter, high efficiency super critical boiler are imperative.
subcritical W flame boiler water-cooling wall pipe pitch, caliber are all bigger; The pipe good rigidity; Therefore its burner nozzle tube panel structure ratio is easier to realize, and overcritical W flame boiler water-cooling wall pipe pitch, caliber are all less, and pipe rigidity is poor; The tube panel seal request is high, so its burner nozzle tube panel structure more complicated.
Summary of the invention:
The purpose of
the utility model provides a kind of burner and tube panel assembles at the scene, and the overcritical W flame boiler of simple 600MW burner nozzle tube panel device is installed.
Above-mentioned purpose realizes through following technical scheme:
the overcritical W flame boiler of a kind of 600MW burner nozzle tube panel device; Its composition comprises: panelized-tube-wall section, hang; Described water-cooling wall adopts the version of membrane wall vertical tube coil; Burner arrangement is the outstanding arch top of water-cooling wall in front and back, described panelized-tube-wall section welding burner nozzle tube panel, and described hanging passed described burner nozzle tube panel; Described burner nozzle tube panel comprises one group of horizontal pipe, connects through steel plate or band steel between the described pipe.
the overcritical W flame boiler of described 600MW burner nozzle tube panel device, described burner is interspersed in the described panelized-tube-wall section for forming a plurality of long and narrow bellows combination of W flame.
the overcritical W flame boiler of described 600MW burner nozzle tube panel device; The water-cooling wall pipe at described burner nozzle tube panel place is the straight tube screen structure that tilts along the burner hearth fore-and-aft direction; Pipe becomes 15 degree to install with the horizontal line angle; Two-layer pipe or three layers of pipe are formed one group of bend pipe, use steel plate reinforcement between bend pipe.
Beneficial effect:
1. the utility model have solved difficult points such as the tube panel pitch is little, the little rigidity of tube outer diameter is poor, spout tube panel seal request height; Adopt two-layer pipe, three layers of pipe to form one group of bend pipe; Use steel plate reinforcement between bend pipe, burner and tube panel assemble at the scene, install simple.
the utility model has solved problems such as overcritical W flame boiler burner nozzle tube panel pitch is little, seal request height, is applicable to the W flame burner peripheral structure design of super critical boiler.

Embodiment 1:
the overcritical W flame boiler of a kind of 600MW burner nozzle tube panel device; Its composition comprises: panelized-tube-wall section 1, hang 2; Described water-cooling wall adopts the version of membrane wall vertical tube coil; Burner arrangement is the outstanding arch top of water-cooling wall in front and back, described panelized-tube-wall section welding burner nozzle tube panel 3, and described hanging passed described burner nozzle tube panel; Described burner nozzle tube panel comprises the i.e. horizontally tube bank of one group of horizontal pipe 4, connects through steel plate or band steel 5 between the described pipe.
Embodiment 2:
The overcritical W flame boiler of
embodiment 1 described 600MW burner nozzle tube panel device: described burner is interspersed in the described panelized-tube-wall section for forming a plurality of long and narrow bellows combination of W flame.
Embodiment 3:
embodiment 1 or the overcritical W flame boiler of 2 described 600MW burner nozzle tube panel device; The water-cooling wall pipe at described burner nozzle tube panel place is the straight tube screen structure that tilts along the burner hearth fore-and-aft direction; Pipe becomes 15 degree to install with the horizontal line angle; Two-layer pipe or three layers of pipe are formed one group of bend pipe, use steel plate reinforcement between bend pipe.
burner nozzle tube panel is assembled into one as an individual components in manufactory, connects into as a whole through welding manner and panelized-tube-wall section at the scene.Burner nozzle inserts the burner nozzle tube panel, but does not weld with tube panel.Combustion system considers to help the low anthracite combustion of volatile matter emphatically, adopts W flame combustion mode.
