Commercial Steam Heating Economizing

Most commercial boilers have a heat capacity between 1.5 to 2 times larger than needed to maintain temperature on non-extreme days.  Economizing increases system efficiency by dynamically changing the pressure-controller’s effective dead-band based upon measured heating load.  Average steam pressure can be varied depending on measured load by extending the burner’s off time which also results in longer, more efficient burn cycles and reduces burner on/off time.
