The system is also known as a lead-lag system. When demand increases, a low selector function blocks the signal, forcing the air flow signal to become the setpoint to the fuel flow controller. A high selector passes the increase to the airflow controller's setpoint. This means fuel flow cannot increase until air flow has begun to increase, i.e.

Lead lag set-up for two steam boilers?? Kmac Member Posts: 5. March 2013. in Strictly Steam. Recently a client of mine had her 600,000 btu steam boiler replaced. The contractor, not me, installed two 300,000 btu burnhams. He told her that the boilers were set up so only one boiler would run, and if necessary the second on would kick in if needed.

Jul 15, 2015 · I am implementing a 3-element boiler drum controller. Has anybody had any success using a lead/lag block with a negative lead time constant? My thinking is that, by effectively "cancelling out" the inverse response of shrink/swell, this could be used to keep the level closer to 50% and decrease the chance of hitting the hi or lo trips.
