Water tube high pressure boiler - ZG steam boiler

High pressure water tube boiler were developed to satisfy the the demand for large quantities of steam at high pressures and temperatures far exceeding those possible with fire-tube boilers. The tubes are outside the steam drum, which has no heating surface and is much smaller than in the fire-tube boiler.

high pressure boiler - industrial boiler and power plant

High Pressure Boiler - Industrial boiler and power plant

High Pressure Boiler is mostly water tube boiler in which water is on the tube side while flue gas flows through the tube, hence transferring heat from flue gas to water with cross flow heat transfer. A steam boiler is a high pressure boiler when it operates with the steam pressure above 6MPa. The high pressure boiler is widely used for power generation in thermal power plant.

On the other hand, they do have boundaries. The output of a conventional dp transmitter has inaccuracies mainly caused by changes of static pressure and water density in each leg, and in the steam and water inside the drum. Water at high pressures experience density changes, independent of those caused by temperature variations.

Sodium Monitoring TECHNICAL NOTE On Power Plant

Chemical contamination concentrates quickly in the drum on high pressure boilers, and may be carried over in the steam delivered to the turbine. Once again, sodium monitoring provides a good indication of the overall steam purity level required to minimise corrosion and avoid deposition of sodium salts on the superheater and turbines.

Boiler (power generation) - Wikipedia

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.

The Importance of Boiler Water and Steam Chemistry

Often, for low pressure building or process heater steam, only a maximum moisture content is specified. This may be as high as 0.5% or as low as 0.1%. Conversely, some turbine manufacturers specify steam condensate maximum cation conductivity, pH, and maximum concentrations for total dissolved solids, sodium and potassium, silica, iron and copper.
