An economizer serves a similar purpose to a feedwater heater, but is technically different as it does not use cycle steam for heating. In fossil-fuel plants, the economizer uses the lowest-temperature flue gas from the furnace to heat the water before it enters the boiler proper. This allows for the heat transfer between the furnace and the feedwater to occur across a smaller average

Steam Boiler | Working Principle and Types Of Steam Boiler

Most modern boilers will operate with the principle of modulation, with the exception of some design types (many copper-fin designs, commercial steam generators, for examples) or smaller, and less than ~30HP commercial boilers, which oftener are set to operate as on-off, low-high-off, low-high-low, etc. Theoretically, modulating will allow the boiler to run and match the load without needing to cycle. So …

Boiler – Fundamentals and Best Practices

Basic Boiler Principles. Water and solids enter the boiler Water leaves the boiler as steam Solids concentrate in the boiler Therefore the boiler water will contain more solids than the feedwater This Concentrating effect is called The Cycles of Concentration or The Cycles.

DC stands for Direct Current and EC stands for Electronically Commutated. DC motors allow the speed of the fans within a Fan Coil Unit to be controlled by means of a 0-10 Volt input 'Signal' to the motor/s, the transformers and speed switches associated with AC Fan Coils are not required. Up to a signal voltage of 2.5 Volts (which may vary with different fan/motor manufacturers) the fan will be in a stopped …
