Three-drum boiler - Wikiped

Author: Dr V T Sathyanathan Three-drum boilers are a class of water-tube boiler used to generate steam, typically to power ships.They are compact and of high evaporative power, factors that encourage this use. Other boiler designs may be more efficient, although bulkier, and so the three-drum pattern was rare as a land-based stationary boiler.

The Effects of Carryover in Steam Boiler Syste

Aug 14, 2018· Effects of Carryover Boiler water carryover can cause deposits to form in valves, heat exchangers, turbines, and superheaters. If deposits are significant, heat transfer and/or turbine efficiency may be reduced. Additionally, carryover can strip away the protective magnetic layer on steam lines, remove the film formed by filming amine programs, cause erosion-induced corrosion, and result in

Seven Telltale Signs Your Boiler Needs To Be Replac

Cast iron boilers, on the other hand, should be considered for replacement if they have been operating for more than 20 or 30 years. Some of these boilers can last even up to 50 years or longer, but even with decent annual maintenance, their efficiencies are much lower than today’s cast iron boilers.
