They ones I've seen are controlled off either boiler or header pressure. I think the pump starts when the pressure drop tells the burner to start. There's such a small water content that you get steam almost immediately. However, when the burner shuts down, the pressure falls like a stone. They're OK on nice even steam loads, but if there's any swing at all, they cycle on and off constantly, and the steam system pressure wanders all over the place. Steam quality can also be an issue as well.
: dear all,
: can someome please explain how do coil steam generators ( called quick steam generators as well ) operate?
: how are they controlled ( pressure or temperature controlled? does the pump control the burner operation as well? ) and if there is any reason for water level control.
