Boiler control - Plant Services

Modulating control improves boiler operation by monitoring the steam or hot-water line to produce a continuous control signal that determines the fuel input. Reductions in steam pressure or water temperature lead to an increase in firing rate. The advantages of burner modulation for combustion control include:

PDF Best Practices for Energy Efficient Boiler Plant Design

3.1.2 Summer boiler Main steam and hot water boilers are sized for winter heating loads. During summer operation the capacity of these boilers is generally many times greater than the load, particularly during overnight low occupancy periods, resulting in excessive cycling on and off. Every time a boiler restarts it goes through a
