A modern recovery boiler consists of heat transfer surfaces made of steel tube; furnace-1, superheaters-2, boiler generating bank-3 and economizers-4. The steam drum-5 design is of single-drum type. The air and black liquor are introduced through primary and secondary air ports-6, liquor guns-7 and tertiary air ports-8.
Although generally a land-based boiler, the four-drum form was also used as a marine boiler, to power large ships. [4] The brick-built setting was replaced with a box-like steel housing, lined with firebrick. The water-tube diameter was reduced to between 2 and 2 + 1 ⁄ 2 inches (50.8 and 63.5 mm). To avoid problems with the water levels ...
A recuperator is a special purpose counter-flow energy recovery heat exchanger positioned within the supply and exhaust air streams of an air handling system, or in the exhaust gases of an industrial process, in order to recover the waste heat. Generally, they are used to extract heat from the exhaust and use it to preheat air entering the ...
Sections of a steam locomotive showing the many fire-tubes which carry the hot gases of the fire through the boiler to heat the water and so create steam. Boiler design is the process of designing boilers used for various purposes. The main function of a boiler is to heat water to generate steam.
The now-asymmetric boiler could pass all of its exhaust gas through the superheated side as the single flow type. [10] The other bank remained in use for purely radiative heating, often with fewer rows of tubes. Alternatively the 'double flow' boiler retained full gas flow through both sides, although only one of these contained a superheater.
However, the Gators went three-and-out on their next drive, giving Ole Miss the ball at midfield. The drive stalled at the 25-yard line but on fourth-and-7, Kiffin chose for a game-tying field ...
Overall, the weather service said that as much as 2 additional feet of new snow is possible near the eastern shore of Lake Ontario through Saturday. Lighter snowfall amounts are expected elsewhere ...
