QUIZ: Boiler Water Treatment Chemical Guidelines — Part II

Steam System Losses and Savings Through Pressure Reduction . A List of Boiler and Steam System Losses. It is useful to summarize the typical causes of boiler and steam system losses. Most of these losses vary . with steam pressure (and temperature) and can potentially be reduced by lowering the steam pressure at the boiler.

Question & Answers Steam Turbines

The fate of the ferrous ion (Fe2+) depends on condensate temperature, pH, and flow conditions. At low temperatures, Fe 2+ reacts with water to form insoluble ferrous hydroxide, Fe(OH) 2.If the condensate stream velocity is high enough, colloidal Fe(OH) 2 is swept into the water and car-ried downstream to deposit elsewhere. In low-flow areas of the condensate system, Fe(OH) 2 deposits near the

Boiler Water Treatment Chemical Guidelines—Part Il continued Because of the associated corrosion problems, chelants are not the preferred treatment choice. However, if the system dictates the use of chelating agents, it can feed under "starvation" conditions, i.e., no free residual in the boiler. Based on the trace level of hardness in the boiler

Multiple Boiler Systems - PM Engineer

Steam lines should ideally be arranged to fall in the direction of flow, at not less than 100 mm per 10 m of pipe (1:100).This slope will ensure that gravity (and the flow of steam), will assist in moving the condensate towards drain points so that the condensate may be safely and effectively removed (see Fig. 15.4).Any steam lines rising in the direction of flow should slope at not less than

The exhaust steam of the new turbine has the same pressure as the old boilers and is used to supply the old turbines. What is an extraction turbine? Answer: In an extraction turbine, steam is withdrawn from one or more stages, at one or more pressures, for heating, plant process, or feedwater heater needs.

Modular steam boilers - Heating Help

May 01, 2005 · The resulting steam would occupy a volume of 6.7 ft3/lb. For acceptable velocities this pressure setting would require a 4-inch steam line (Sch. 40). However, if the same boiler is set at 200 psig, steam tables show the volume reduces to 2.14 ft3/lb, requiring only a 2-inch steam pipe. Look at the economic impact. A 200-foot, 4-inch, Sch. 40 main steam line would cost three times more than a 200-foot, 2-inch main line.

POWER BOILERS ASME SECT. I & POWER PIPING - Steam …

Where two or more boilers are connected to a common header, in addition to the boiler main stop valve, a second valve shall be incorporated in the steam connection, and this valve shall be capable of being locked in the closed position. This allows better protection for a decommissionedboiler when isolated from the distribution header.

The steam that goes to the main engines, ship's service turbine generators, boiler internal desuperheater and main feed pumps (on certain ships) is called main steam. Steam generation in a conventional steam plant begins with the boiler. The D-type boiler has been installed in US Navy ships since 1950.
