Abstract
The invention discloses a 600MW supercritical W flame boiler burner nozzle tube panel device. A supercritical W flame boiler water-cooling wall pipe has smaller pitch and pipe diameter, poor pipe rigidity and high sealing requirement on a tube panel, thus a burner nozzle tube panel has a more complex structure. The 600MW supercritical W flame boiler burner nozzle tube panel device comprises a water-cooling wall tube panel (1) and a hanger (2), wherein a water-cooling wall is of structure manner that a membrane panel is vertical to a tube ring, a burner is arranged on protruding arc upper parts of the front water-cooling wall and the rear water-cooling wall, the water-cooling tube panel is welded with the burner nozzle tube panel (3), the hanger penetrates through the burner nozzle tube panel which comprises one group of horizontally-arranged tubes (4), and the pipes are connected through a steel plate or flat steel (5). The 600MW supercritical W flame boiler burner nozzle tube panel device is used in a supercritical boiler W flame burner peripheral structure.
Description
technical field:
the present invention relates to a kind of novel jet pipe screen device, be specifically related to a kind of 600MW overcritical W flame boiler combustor spout tube panel device.
background technology:
current Kazakhstan pot uses anthracitic W flame boiler and is subcritical, and steam parameter is low thus cause power plant's operational efficiency 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 wall pipe pitch, caliber are all larger, pipe good rigidity, therefore its burner nozzle tube panel structure comparison easily realizes, and supercritical W-shaped flame boiler water-cooling wall pipe pitch, caliber are all less, pipe poor rigidity, tube panel seal request is high, therefore its burner nozzle tube panel complicated structure.
summary of the invention:
the object of this invention is to provide a kind of burner and tube panel assembles at the scene, simple 600MW overcritical W flame boiler combustor spout tube panel device is installed.
above-mentioned object is realized by following technical scheme:
a kind of 600MW overcritical W flame boiler combustor spout tube panel device, its composition comprises: panelized-tube-wall section, hanging, described water-cooling wall adopts the version of membrane wall vertical tube coil, the arch top that burner arrangement is given prominence at front and back water-cooling wall, described panelized-tube-wall section welding burner nozzle tube panel, described hanging is through described burner nozzle tube panel, and described burner nozzle tube panel comprises one group of horizontal pipe, is connected between described pipe by steel plate or band steel.
described 600MW overcritical W flame boiler combustor spout tube panel device, described burner is the multiple long and narrow bellows combination forming W flame, is interspersed in described panelized-tube-wall section.
described 600MW overcritical W flame boiler combustor spout tube panel device, the water-cooling wall pipe at described burner nozzle tube panel place is the straight tube screen structure tilted along burner hearth fore-and-aft direction, pipe becomes 15 degree to install with horizontal line angle, two-layer pipe or three layers of pipe form one group of bend pipe, use steel plate reinforcement between bend pipe.
beneficial effect:
1. the invention solves the difficult points such as tube panel pitch is little, the little poor rigidity of tube outer diameter, spout tube panel seal request are high, adopt two-layer pipe, three layers of pipe form one group of bend pipe, with steel plate reinforcement between bend pipe, burner and tube panel assemble at the scene, install simple.
2. the invention solves the problems such as overcritical W flame boiler combustor spout tube panel pitch is little, seal request is high, be applicable to the W flame burner peripheral structure design of super critical boiler.
