Many types of baffle arrangements are used with bent-tube boilers. Usually, they are installed so that the inclined tubes between the lower drum and the top front drum absorb 70 to 80 percent of the heat. The water-tube boilers discussed above offer a number of worthwhile advantages. For one thing, they afford flexibility in starting up.
The centres for the water-tubes, G and H, should be laid out, in accordance with Fig. 88, on the tops of B and C and the lower part of A, along lines scribed in the manner explained on p. 207. Tubes H must be bent to a template to get them all of the. FIG. 88.-Two arrangements for tube holes in multi tubular boiler.
A tube sheet is a plate, sheet, or bulkhead which is perforated with a pattern of holes designed to accept pipes or tubes. These sheets are used to support and isolate tubes in heat exchangers and boilers or to support filter elements. Depending on the application, a tube sheet may be made of various metals or of resin composites or plastic.
All Bryan boilers are built in accordance with the requirements of the ASME Boiler and Pressure Vessel Code. Efficient "Flexible Water Tube" design The Bryan bent water tube provides rapid internal circulation — for maximum heat transfer and operating effi ciency. Easily replaceable tubes
End of Chapter Answer Guide - 2nd Class - A3 Page 407 7. Using a simple sketch, describe natural circulation in a boiler. In a simple water tube circuit, the downcomer is unheated and the riser is heated. The heated steam-water mixture has less mass than the cooler water on the unheated side and the unbalance forces the left-hand column to
If a boiler having the system of water flow inside of its tube and heat flow system present in outside then it will be called a Water Tube Boiler. Water Tube Boiler can have Straight and Bent Tube, Cross, and Vertical Drum, Horizontal, Vertical and Inclined Tubes, Single or Multi Drum, Sectional and Box type Header.
In my opinion, the new Greenwood will have a short life because of the straight tube design. Each tube will have a different expansion rate and will put a great amount of stress on the headers. Every water tube boiler built uses a bent tube design for this reason.
C. Bryan bent water tubes are ﬂ exible, individually replaceable with-out welding or rolling. Never more than two tube conﬁ gurations. D. Boiler tube and furnace area access panel: heavy gauge steel casing with 2" high temperature ceramic ﬁ ber and insulation, bolted and tightly sealed to boiler frame.
