3 Types of Circulation In Boiler - Water Treatment Basics

Continuous circulation of coal and sorbent improves mixing and extends the contact time of solids and gases, thus promoting high carbon utilization and high sulfur capture efficiency. Heat in the flue gas exiting the hot cyclone is recovered in the economizer. Flue gas passes through a baghouse, where particulate matter is removed.

SZS Gas(oil) Fired Water Tube Hot Water Boiler. The boiler is a double-drum longitudinal "D" type structure. The water, steam or steam-water mixture flows in the tubes. The flame burns and the flue gas flows outside the tubes, to ensure the good water circulation system, thus ensuring the long-term stable operation of the boiler.

Gas re-circulation selective catalytic reduction system

Aug 23, 2018 · A boiler's circulator pump is used to remove hot water from the boiler, and then pass it into heating devices such as the radiator or a convection pipe system. The power of the pump is enough to cause the water to travel right back up to the boiler from the pipework. Using a circulation pump is a great way of keeping water traveling throughout the system.
