In watertube boilers, boiler water passes through the tubes while the exhaust gases remain in the shell side, passing over the tube surfaces. Because tubes can typically withstand higher internal pressure than the large chamber shell in a firetube, watertube boilers are used where high steam pressures (3,000 psi, sometimes higher) are required.[PDF]
superheat. Steam quality ranges from 0 to 100% and is defined as the ratio of the amount of saturated steam vapor to the total steam amount (which may consist of both saturated steam vapor and liquid). A 100% steam quality translates to zero amount of saturated steam liquid and, in this condition, the steam is termed to be “dry.” 4.File Size: 258KB
Oct 26, 2017 · The in particular part is thrown in there because a lot of boiler systems heat a fluid other than water. Glycol, oil, and process chemicals to name a few. But to keep things fairly simple, we will stick with water. So your basic boiler burns a fuel source to heat water. A water heater, basically.
