Abstract
A control for a vapor steam generator as used with a pellet mill senses the exhaust temperature of the steam and controls it by modulating the flow of air/gas to the burner independently of the flow rate of moisture such that steam having a constant moisture content can be produced at varying temperatures. The constant moisture content steam is desirably used in the pellet mill by ratioing the flow of moisture to the flow of dry material such that finished pellets having a pre-determined moisture content can be reliably produced.
