Two primary principles are used with this form of tank design: thermal and vacuum. This depends on which type of boiler being used. Each principle also has different pump construction requirements. Thermo principle. A tank using the thermal principle is connected to the atmosphere. This design is normally used in smaller plants.
Burners inject air and fuel through a distribution system that mixes them in proper concen - trations so combustion can occur. Most boilers use natural gas, fuel oil, or coal burners to provide heat to the boiler. The key components of natural gas burners include pilots, impellers, spuds, spiders, and igniters.
Bag Filters are 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. Bag-house Filter Types. There are different types of Bag Filters such as. Shakers; Reverse
of bag life. The 75,000 lb/hr boiler is fired with 7% ash, bituminous coal with a sulfur content of 2.3%. The firing equipment is a spreader stoker. No mechanical collectors are installed ahead of the baghouse. The gas temperature entering the baghouse is 350°F. The bags are fiberglass with an air to cloth ratio of 3.5. The bag cleaning method is reverse air
Bags are cleaned by a short burst of compressed air injected through a common manifold over a row of bags. The compressed air is accelerated by a venturi nozzle mounted at the reverse-jet baghouse top of the bag. Since the duration of the compressed-air burst is short (about 0.1 seconds), it acts as a rapidly moving air bubble, traveling through the entire length of the bag and causing the bag surfaces to flex.
