Description

Technical Field

[0001] The utility model relates to the technical field of power station boilers, in particular to a training simulation frame for heat treatment after welding of power station boiler pipelines. Background Art

[0002] A power plant boiler, in layman's terms, is a boiler used to generate electricity in a power plant. They typically have a large capacity, with main units reaching 600MW. More advanced units, such as ultra-supercritical boilers, can reach capacities of up to 1000MW. There are two main types of power plant boilers: pulverized coal boilers and circulating fluidized bed boilers. These two types of boilers are predominant in power plants. The primary difference between fluidized bed and pulverized coal boilers is the fuel state—liquid versus powdered coal. During the assembly of power plant boilers, training on heat treatment simulation racks is necessary to familiarize new operators with heat treatment procedures and enhance their skills.

[0003] The published patent document, CN215895727U, discloses a simulation frame for training post-weld heat treatment of power plant boiler pipes. The frame comprises a base and a support frame. A bottom frame is connected to the base via the support frame. A top frame is disposed above the bottom frame. Reducer and reducer pipe fittings and risers are disposed on the bottom and top frames. At least four small-diameter pipe heads are evenly distributed on the exterior of the risers and on the exterior of the pipe wall on one side of the top frame. A pipe bank is disposed on the pipe wall on the other side of the top frame. This simulation frame simulates the types and fixed positions of welded joints requiring post-weld heat treatment in various systems of a power plant boiler. This simulation frame can be used to conduct post-weld heat treatment simulation training for pipe banks, pipe seats, reducers, tees, elbows, and large-diameter pipes at various locations within the boiler, thereby standardizing the post-weld heat treatment process, standardizing the operating methods of personnel, improving their skills, and ensuring the quality of welded joints.

[0004] The existing heat treatment training simulation frame is not convenient for adjusting the angle when in use, and the positions of some pipe rows and pipe heads are not conducive to heat treatment training for operators. Therefore, a heat treatment training simulation frame for power station boiler pipelines after welding is needed. Utility Model Content

The angles of the rows of pipes and pipe heads on the simulation frame can be adjusted, so that the operator can perform heat treatment training at a more comfortable angle, which is convenient and practical.
