An Introduction to Boiler Control Systems

This course provides an introduction to criteria for the design of heating plant instrumentation. A heating plant may contain one or more boilers. The plant may be an individual plant serving a single building or a compact group of buildings, or a central plant serving many buildings and facilities through an extensive distribution system. The heating plant instrumentation discussed is, in general, for a saturated steam power boiler heating plant. The information provided may also be applicable to Low, Medium, and High Temperature Hot Water heating plants, but does not cover all of the requirements of those plants, such as control of water pressurization and circulation systems. The information may also be applicable to superheated-steam power plants, but does not cover the all of the requirements of those plants, such as steam extraction, reheating, steam turbine control, and cooling water controls.
