The high pressure boiler tubes are often working in the condition with high pressure, high temperature and the interaction of the high temperature flue gas and vapor, which may lead to oxidation and corrosion on the tubes.

Steam Pressure Reduction: Opportunities and Issues - NR

Steam pressure reduction is the lowering of the steam pressure at the boiler plant by means of the pressure setting on the boiler plant master control. Steam pressure reduction affects mainly the high pressure part of the steam system.

Boiler (power generation) - Wikiped

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Boiler Operation Boiler Maintenance | HSB Locomoti

The safety or safety relief valve must be set to open at or below the maximum allowable working pressure established by the manufacturer. This is the maximum pressure at which the designers have determined the boiler can be safely operated. The maximum allowable working pressure is listed on the required boiler nameplate or stamping.

High Pressure Boilers: Features and Advantages ~ ME Mechanic

A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.

• Poor condition of boiler pressure parts with high erosion, overheating, external corrosion, oxide deposits, weak headers and pressurized furnace etc. • Poor water chemistry has affected the condition of boiler and turbine in many cases. The water treatment plant is often in a dilapidated condition.

High-Pressure Boiler Inspection Procedures (with Checklis

A high-pressure boiler is defined as a boiler in which steam or vapor is generated at a pressure equal to or greater than 15 psig, or a boiler in which water is heated at a temperature of 250°F and a pressure greater than 160 psig, when water is heated for use external to the boiler itself.

Boiler - Wikiped

The design of any superheated steam plant presents several engineering challenges due to the high working temperatures and pressures. One consideration is the introduction of feedwater to the boiler. The pump used to charge the boiler must be able to overcome the boiler's operating pressure, else water will not flow. As a superheated boiler is
