Problems solved by technology

In traditional technology, a non-metallic compensator is used to connect the hot primary air pipe interface at the outlet of the air preheater to compensate for the displacement of the air preheater interface, but the setting of the compensator will increase the blind plate force of the pipe. It is difficult to completely eliminate the influence of the blind plate force on the compensator due to the support and hanger setting, and the compensator at the interface will be pulled down, which will seriously affect the safe operation of the unit

Embodiment Construction

[0022] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] like figure 1 As shown, a boiler hot primary air pipe hanger layout structure includes a hot primary air pipe 100 and a support frame (not shown in the figure). The hot primary air pipeline 100 includes an air preheater hot primary air interface 110 , a pipeline elbow section, a pipeline vertical section 140 and a pipeline outlet 150 arranged in sequence. The pipe elbow section is provided with an elastic hanger, and the vertical section of the pipe is provided with a three-dimensional compensator 500 and a combined hanger 400, and the elastic hanger and the combined hanger 400 are both connected to the support frame.

[0024] The compensator is canceled at the hot primary air interface 110 of the air preheater, and the air preheater hot primary air interface 110 transitions to the circular hot primary air pipe part through the square and round...

Abstract

The invention discloses a boiler hot primary air pipeline hanger arranging structure. The structure comprises a hot primary air pipeline and a supporting frame, wherein the hot primary air pipeline comprises an air pre-heater hot primary air connector, a pipeline elbow section, a pipeline vertical section and a pipeline outlet which are connected in sequence, the pipeline elbow section is provided with an elastic hander, a three-dimensional compensator and a combined hanger are arranged on the pipeline vertical section, and both the elastic hanger and the combined hanger are connected to the supporting frame. By the adoption of the structure, the blind flange stress at the position of the air pre-heater hot primary air connector can be eliminated, the stress at the position of the connector can be shared, and the risk that a compensator is damaged under pulling at the position of the connector can be avoided.

Description

technical field [0001] The invention relates to the technical field of thermal power generation, in particular to a boiler hot primary air pipe hanger layout structure. Background technique [0002] The thermal primary air pipeline in a thermal power plant is a pipeline that provides pulverized coal drying medium and combustion air. The thermal primary air pipeline is evenly stressed, and the safety of the piping system plays a very important role in the safe operation of the power plant. In traditional technology, a non-metallic compensator is used to connect the hot primary air pipe interface at the outlet of the air preheater to compensate for the displacement of the air preheater interface, but the setting of the compensator will increase the blind plate force of the pipe. It is difficult to completely eliminate the influence of the blind plate force on the compensator due to the proper support and hanger setting, and the compensator at the interface will be pulled down,...
