JB10992-2020-T "Wet flue gas desulfurization equipment - flue gas damper door" standard technical specification
1. The smoke baffle has 100% tightness at the design pressure and design temperature. The operation of all baffles is flexible, reliable, and easy to maintain. Unless otherwise specified, the baffle will have intelligent electric actuators for remote control and on-site manual operation set up in the aisle or floor, and will also provide baffle position indicators.
2. The smoke baffle can operate under maximum pressure difference and close tightly without bending or jamming, making it particularly suitable for various environments without deformation or jamming during operation. And the design and position of the baffle minimize the accumulation of dust on the baffle sheet.
3. The actuator is equipped with a positioning switch, a two-way rotation switch, an accident handwheel, and a mechanical interlock for maintenance.
4. The baffle is equipped with a limit switch indicating whether it is fully open or fully closed. These limit switches are not affected by the switch of the driving device.
5. The speed of the electric actuator for the electric tailgate meets the operational requirements of the project.
6. The complete set of baffle devices provided includes all necessary seals and control components for the frame, plate, electric actuator, and sealing system.
7. Horizontal arrangement of baffle spindle. The spindle is made of suitable steel and special attention is paid to the design of the frame, shaft, and bearings to prevent dust from entering and to prevent deformation caused by high temperatures.
8. The end of the baffle door shaft is equipped with clear and visible markings indicating the position of the baffle plate, and is equipped with interlocking limit switches. The baffle door body is equipped with a handwheel, which can manually adjust the valve opening.
9. Access to the interior of the flue can be obtained through the inspection holes near both sides of the baffle.
10. Each baffle door is not equipped with a sealed air system, and the air leakage rate of the flue baffle door when fully closed is less than 1%. At the pre flange of each axis, there is no leakage of cold or hot flue gas, whether in the open or closed state. The material and thickness of the baffle door should meet the requirement that it will not deform under the condition of temperature difference.
11. After the assembly of each baffle door, an overall performance test shall be conducted in the factory. The supplier shall be responsible for solving any problems caused by the design and manufacturing quality of the baffle door during hot commissioning. The overall structure of the louvered flue damper door does not deform or jam under the condition of significant temperature differences between hot and cold.
