water tube two drum boiler Agent expansion

Water Handbook - Steam Purity | SUEZ

In the modern water-tube boiler, separation of the steam-water mixture entering a relatively small steam drum is a complex process. For every pound of steam generated, as many as 15-20 lb of water may circulate through a drum. As a result, 99.97% or more of the circulating water must be removed from steam to ensure the desired steam purity.

LITERATURE ON BOILER TUBE EXPANSION

drum. Tubes up to (but not including) 2 inches in OD should project 3/16 inch to 5/16 inch (4.7 mm to 7.9 mm) in to the drum or header. Tubes of 2 inches OD and larger should project 5/16 inch to 7/16 inch (7.9 mm to 11.1 mm) in to the drum or header. In tube joints where the tube and hole measurements can be obtained, the correct amount of expansion

Water-Tube Boilers - Trains Magazine - Trains News Wire

Oct 14, 2019 · I am aware of several attempts to build locomotives with high-pressure water-tube boilers spanning from late 1920s to early 30s, often either using the Schmidt system or a water-tube firebox combined with a fire-tube boiler. Something I've wondered is why more locomotives were never tried with a marine three-drum Yarrow or Admiral boiler.

Stirling Water-tube Boilers - ASME

He patented the Stirling four-drum boiler in 1892 and then the bent-tube steam boiler in 1893. Water-tube boilers were of value in low-headroom conditions to produce continuous and economical production of steam even when using poor feedwater or under sudden load swings. Babcock and Wilcox, which had introduced safety boilers in 1867, purchased

The Story of the Boiler - Wonders of World Engineering

In the Hawthorn-Armstrong water tube boiler there are two steam drums at the top and two water drums at the bottom, the generator tubes passing one another scissors-fashion, the superheaters being mounted above the tubes on either side. The water tube boiler is capable of raising steam to a much higher pressure than the shell or fire tube boiler.

Roll the tube to what you estimate to be a good tube joint (by feel or an estimated torque setting) and check the ID of the tube with a tube gauge. Take caution not to over roll as it can cause damage. Subtract "F" from the rolled diameter to determine the actual amount of expansion (tube wall reduction) on the inside diameter of your tube.
