FIG. 39.6 This instrument is used to monitor corrosion-pro-duced hydrogen concentrations in steam. water salts, such as silica and sodium compounds; or it may be caused by foam-ing. Carryover is most often a mechanical problem, and the chemicals found in the
Get priceIn some steam drum designs, water level is extremely critical because the baffling may isolate a generating section of the boiler when the steam drum water level falls below a certain point. Thin-lipped bursts also occur in superheater tubes when steam flow is insufficient, when deposits restrict flow, or when tubes are blocked by water due to a rapid firing rate during boiler start-up.

Get priceThe steam-generating boiler's roots go back to the late 1700s and early 1800s with the development of the kettle-type boiler, which simply boiled water into steam. The water was placed above a fire box and then boiled into steam. It wasn't until around 1867, with the development of the convection boiler, that the steam-generating industry
