The layout of the tubes involves the number of passes the tube will make to pass the heat from the boiler furnace before being discharged. These can be two- pass and three pass boiler. Depending upon the layout of tubes boilers can be two pass or three pass boilers. Two pass boilers: In two pass the combustion gases travels two times in the boiler.

lexie@zozen.com > Get A Quote >The tubes frequently have a large number of bends and sometimes fins to maximize the surface area. This type of boiler is generally preferred in high pressure applications since the high pressure water/steam is contained within narrow pipes which can contain the pressure with a thinner wall.

The boilers exploded because they could not be safely pressurized with the existing technology.

This helps to prevent any situation in which the boiler has to relieve itself of a large amount of pressure all at once, making a serious explosion virtually impossible.
