Issues with clogs in the pulverized coal pipeline of the space furnace
Thread Content
The pulverized coal pipeline in the space furnace is blocked. How can one determine whether it is the inflation in the feed tank that causes the blockage or the coal control valve? And what should be done to resolve the blockage?
If the cone is blocked or the valve is blocked, the pressure in the pulverized coal pipe will change, right?
The overall pressure of the cone plug is low, while only the pressure at the back of the valve plug is low; a comparison shows this
Are you sure the pressure is low after blocking it? If the flow is blocked yet it still passes, the pressure will actually increase; moreover, if the valve is blocked, pressure will remain constant as the fluid keeps building up ahead
Should you consider ultrasonic descaling and anti-scaling equipment? Tianjin Chengtaixiang Technology Development Company develops and manufactures its own ultrasonic equipment for scale removal and prevention. We can carry out customized technical design to meet your company’s specific scale removal needs. For more details, please contact Director Hong at 022-84262080 or mobile phone number 13902118865
Two pressure changes in the coal dust pipeline
The backflow prevention effect is achieved in the conical section; it can be achieved using a single-angle valve. Can the angle valve be removed for cleaning?
