ELECTRIC HOT WATER STEAM BOILERS

The principle of the device is a mechanical linkage that connects a float to a switch (or switches) that, in turn, is tied into the burner circuit. The float is in an external chamber and it rises and falls with the boiler water level. If the float drops too low, the linkage opens the switch and trips the burner control circuit.

Boiler Controls—Testing and Maintenance - FMLink

Burner modulation. Modulating control is a basic improvement in controlling combustion. A continuous control signal is generated by a controller monitoring the steam or hot water line. Reductions in steam pressure or hot water temperature lead to an increase in firing rate. The advantages of introducing burner modulation in combustion control
