Electrostatic Precipitator - an overview | ScienceDirect

An ESP installed upstream of the air heater, where flue gas temperatures are significantly higher, is known as a hot-side ESP. The effectiveness of an ESP depends in part on the electrical resistivity of the particles in the flue gas. Coal with a moderate to high amount of sulfur produces particles that are more readily controlled.

What is a Combi Boiler? Guide to Types, Size, Pros & Cons

What a condensing boiler has that non-condensing boiler does not is a Flue Gas Heat Recovery System. As any boiler works it produces waste flue gases and heat and in an old, non-condensing boiler these gases would be wasted. A Flue Gas Heat Recovery System captures the heat from these waste flue gases and recycles it to preheat the new, cold
