Abstract
Description
Technical Field
[0001] The utility model relates to the field of superheater pipe clamps, in particular to a screen type superheater pipe clamp. Background Art
[0002] As an important component of the boiler, the platen superheater mainly increases the steam temperature to increase the steam's working capacity, thereby improving the thermal efficiency of the power plant. During operation, the platen superheater will shake with the furnace flame disturbance, so the platen tube clamp is used to clamp the tube row of the platen superheater to prevent the tube row from shaking.
[0003] The following problems exist when using clamp-screen tubes to fix the tube bank: 1. Under normal circumstances, there will be a certain gap between the clamp-screen tubes and the tube bank, and the tube bank is prone to small swings. After the tube bank swings, mechanical friction will occur at the contact point between the clamp-screen tubes and the tube bank. If the unit is run for a long time, it will cause the tube bank to burst; 2. When the combustion in the furnace is unstable, pressure fluctuations will occur in the combustion chamber. When the frequency of the pressure fluctuations is close to the natural frequency of the tube bank in the furnace, furnace noise or resonance will be emitted, causing fatigue damage to the tube bank.
