Boiler-Tuning Basics, Part I - powermag.com

In any coal-fired boiler, airflow demand is a function of the boiler firing rate or boiler demand (Figure 3). Gas- and oil-fired boilers have lower O2 requirements at higher loads. 3. Extra air is a good thing. A typical O2 set point curve for a coal-fired plant is a function of boiler firing rate or boiler demand.

What is the function of economizer in steam power plant

A common application of economizers in steam power plant is to capture the waste heat from boiler stack gases (flue gas) and transfer it to the boiler feedwater. This raises the temperature of the boiler feedwater, lowering the needed energy input, in turn reducing the firing rates needed for the rated boiler
