A   steam boiler   assembly, be it any fuel (solid/liquid/gaseous) used for combustion, the flue gases coming out of the Induced draft fan, coming from air preheaters and dust collectors, enters the chimney to conclude this process before getting released to the atmosphere. Self-supported type  Chimneys  can be provided suiting the boiler size. It can be designed and manufactured as per IS-6533 standard to ensure compliance. Working The chimney’s working is based on the natural draft or stack effect. As we know, the density of a gas reduces, with rising in its temperature, so because of this reason when the flue gases enter the chimney, the buoyancy forces of air come into action and help in carrying the flue gases out of the chimney.  In the case of a Boiler assembly employing an Induced Draft Fan , the flue gases are brought to the chimney by this fan and then buoyancy forces deliver them to the atmosphere. These buoyancy forces depend upon th...

What is Bag Filter? A Bag Filter is an air pollution controlling industrial equipment , used prominently in a Steam Boiler House Assembly. It is used to control the levels of sulfur dioxide and others. There are different types of Bag Filters such as Shakers, Reverse Air and Pulse Jet type, with Pulse jet type being the most promising one of outstanding results. A Pulse Jet type Bag Filter consists of a Four-sided hollow metallic body which is conical at the downside. Also, a vertical squirrel cage type arrangement is there for supporting and holding the filter bags. These squirrel type cages are covered by filter bag material. After covering these cages with Filter Bags , it appears as a Pipe like geometry  Downside of this cage is blind while the other side is open for the flue gases exit and pressurized air inlet. During the operation of a Steam Boiler , the flue gases leaving the Boiler enters the Bag filter body. Now, these flue gases come in contact with ...
