RE: Low flow

Home Forums Coking Technical Heaters & Furnaces Low flow RE: Low flow


Alfredo Velasco

Important question:

Some of them are:

1. Fuel gas trip, and Velocity Steam
It is known that emergency steam means the steam injected into the radiant box in case of a fire or explosive atmosphere.

2. It is recommended to have one flow control valve per flow pass in coker heaters, just to keep the bulk temperature of all passes to a similar value. It is called “COIL BALANCE”. Of course, flow, pressure and temperature are key variables.

3. Increment the velocity steam if a problem of low flow occurs.

Hope this help
