The Electrode generator is locally managed by a PLC-based system that controls every aspect of the boiler which includes control of water level, pressure and KW limit. All safety devices will also be monitored by the PLC. Interface to the PLC by an operator is accomplished through a HMI device that communicates directly with the boiler PLC.
Effective Boiler-Level Control. By most manufacturers' standards, high-quality steam is 99.5-percent dry saturated steam. For a boiler to provide an appropriate amount of such steam safely, efficiently, and at the correct pressure, the amount of water inside of the boiler must be carefully controlled.

It is analogous to the internal heating system in a car. For instance, a hot water heater uses a thermostat to control the temperature of the Temperature controllers in industry work much the same way they do in common an alarm, or to retransmit the process value to a programmable logic controller (PLC
Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1), it is easy to see that because the tube diameter is significantly smaller, much higher pressures can

PLC is a digital computer used for automation of the electromechanical process. PLC is designed for multiple inputs and output arrangements, extended temperature ranges, immunity to electrical noise and resistance to vibration and impact.
water can occur in a steam boiler will also hold true for a hot water boiler. It is a common misconception that a pressure reducing valve, used to fill a hot water system initially, will keep the boiler and system full under all circumstances. But when it is realized that a pressure reducing valve is normally set
enables remote monitoring of the Boiler Control System from anywhere in the world. The Hawk ICS may be used on mo st types of steam and hot water boilers, including firetube, industrial watertube, and commercial watertube. It is designed to operate with a gas, oil, or combination burner using a single-point modulating control.
