Embodiment Construction

[0013] combine figure 1 It can be seen that the embodiment of the present invention is: the spiral section of the water cooling wall is installed at the right end of the curved section of the water cooling wall, and the vertical section of the water cooling wall is installed at the upper end of the curved section of the water cooling wall; the curved section of the water cooling wall adopts a telescopic hose; the water cooling wall Each section is directly connected with a water tank.

[0014] The core idea of ​​the embodiment of the present invention is: by adopting the spiral water wall structure in the horizontal section of the steam injection boiler, the strain resistance of the water wall tube bundle due to changing working conditions is improved, and the water flow resistance at the elbow is reduced; The horizontal and vertical sections of the steam injection boiler adopt stretchable and curved metal hoses to reduce the impact of boiler shaking and reduce the installatio...

Abstract

The invention relates to the technical field of a steam-injection boiler, and designs a spiral water cooling wall structure of the steam-injection boiler. The spiral water cooling wall structure comprises a water cooling wall spiral section, a water cooling wall bending section and a water cooling wall vertical section, the water cooling wall vertical section is installed at the upper end of the water cooling wall bending section, and the water cooling wall spiral section is arranged on the right edge of the water cooling wall bending section. By means of the designed spiral water cooling wallstructure of the steam-injection boiler, the boiler running variable working condition requirement can be met; due to the fact that a tube bundle can absorb heat in a balanced manner, the strain force resistant capacity during variable working conditions is improved, the water flow resistance is balanced, and the bend impact is reduced; and through the special structure of the water cooling wallbending section, the requirement of the steam-injection boiler to the space position is low, and the good application prospect is achieved.

Description

technical field [0001] The invention relates to a spiral water-cooled wall structure of a steam injection boiler, which belongs to the field of changing working conditions and improving the operation time limit of the steam injection boiler. Background technique [0002] In the boiler, the water wall is the main heating part of the boiler. It is composed of tube bundles distributed around the boiler furnace, and the inside is flowing water or steam, which is used to protect the furnace and absorb the heat of the flame. The existing spiral water-cooled wall can adapt to the variable working conditions of the boiler, but there is no spiral water-cooled wall structure applied to the steam injection boiler. Steam injection boilers often operate under variable conditions. In order to reduce the strain resistance of the water wall when steam injection boilers operate under variable conditions, and improve the safety factor and service life of steam injection boilers, a spiral wate...
