12/6/2017 · High pressure boiler applications require further pretreatment of feedwater to remove hardness, alkalinity, and silica. In this case, complete demineralization of the makeup is required. Internal treatment of the boiler water includes keeping the hardness in solution by the addition of chelants such as EDTA, or by the controlled precipitation of solids by the addition of phosphate.

A high pressure watertube boiler[1] (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace
Read MoreThese are developed because of rising cost of fuel and restrictions on air pollution. Modern power generation plants generally use high pressure boilers. These high pressure boilers have pressures above 140 bar and the temperature may be up to 540 – 610°C. High pressure boilers use both natural and forced circulations.

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.

Where the process does not allow for this, or if the required water temperature is above 100 C, the use of High-Pressure Hot Water Boilers is a tried, tested and proven solution. Clearly, working with higher pressures means a stable, robust boiler design is essential and Babcock Wanson achieve this by offering their TPC-AS High-Pressure Hot Water Boiler.
