The flue gas baffle door is an essential part of the desulfurization system, and its ceramic staining is the blockade and blockade of the tube bundle flue. In the boiler system and FGD system, the flue gas damper door is monopolized in several parts such as the inlet, the outlet and the bypass. Is it necessary for the flue gas damper to bypass? Let's talk about this title issue above.
1. The setting of the bypass baffle door is not conducive to the pressure difference tube bundle
There is no flue gas damper in the bypass flue of the desulfurization system, which will improve the recovery of the flue gas pressure difference between the inlet and outlet sides of the FGD system. In actual operation, it must be guaranteed that the pressure difference is zero, but this is in the desulfurization system. What is difficult to manage and implement in Zhongbi Li is that when the flue gas working conditions are stubborn, the pressure difference of the tube bundle is more difficult.
2. The setting of the bypass baffle door is not conducive to desulfurization.
The setting of the flue gas damper door on the bypass flue will prevent the flue gas from permeating each other in the actual operation of the desulfurization system. When the desulfurization system is in operation, the net flue gas may or may enter the FGD system, and the original flue gas may or may be indirectly discharged into the chimney. The flue gas damper door of the bypass flue acts as a barrier to contamination. The work of improving the desulfurization system is obligatory.
3. The setting of the bypass baffle door is not conducive to reducing the cost of the fan
After the bypass baffle door is installed in the desulfurization baffle door system, the pipe bundle of the bypass flue is more flexible. Therefore, when the desulfurization system chooses a booster fan, it is also a rise in the consideration of the margin or steady reduction. The cost and operating cost of the wind turbine are improved, and the investment sensitivity and operating economy of the desulfurization system are improved.
4. The setting of the bypass damper door is not helpful to reduce the impact on the boiler when the system is opened and closed
When the flue gas desulfurization system is blocked or blocked, the flue gas will pass through the bypass operation. When the inlet damper door and the outlet damper door are blocked at the same time, the setting of the bypass damper door can control the flue gas operation volume and harmonize The opening and closing of the bypass flue and the desulfurization flue gas damper door system reduces the pressure difference between the two flues, and the defense has a clear effect on the negative pressure of the boiler furnace, causing MFT.
