Catalytic spool purge air
Thread Content
The purge air for the valve actuators in this device often doesn’t flow properly, which causes the valves to stick. Do any of the other units have any good solutions to recommend?
First, figure out what’s causing the obstruction Wind carries water? Is the orifice plate designed to be too small? Then make targeted adjustments to the operations.
Here, the slide valve is loose; low-pressure steam is used for ventilation, and the steam vent is set to a low level to prevent excessive gas release
Handle it quickly; it will affect fluidization；
What is the pressure drop? Is the low-pressure steam at 1.0?
We also use steam, with a 2.0 orifice plate
