Boiler Control  Introduction . Boilers are the primary source of steam and hot water generation in industrial processing plants where steam demands vary very frequently according to the requirements. Hence, a well designed boiler must be capable of giving immediate response to these load demand variations. While doing so it must also maintain its efficiency and safety features.

A fusible plug is a threaded metal cylinder usually of bronze, brass or gunmetal, with a tapered hole drilled completely through its length.This hole is sealed with a metal of low melting point that flows away if a pre-determined, high temperature is reached. The initial use of the fusible plug was as a safety precaution against low water levels in steam engine boilers, but later applications

Gowri Shankar Abstract--This paper outlines the various stages of operation involved in the conversion of a manually operated boiler towards a fully automated boiler.
The PLC modulates the firing rate of the boilers, along with control of other functions. If one boiler is not sufficient to meet the heat demand, additional boilers are brought online by the PLC
OxyChem uses three (3) different fuels in these boilers. Moore Products' APACS control hardware was used, with redundant ACMs for combustion control and a QUADLOG Safety PLC for burner management. An InTouch HMI was developed for monitoring and control of the boiler systems.
III. BOILER CONTROL Techniques used in boilers are similar to other methods developed for process control and used terminology somewhat different to the main control community wedded to servomechanisms. Reference  describes these techniques in a seminal work. Many industrial procedures in use today are included in this reference with the
The Hydronic System Control is a PLC based boiler sequencing and modulation control for hydronic heating applications.
