In high pressure boilers, where the rate of heat transfer is very high, scaling of tubes cannot be tolerated Demineralized water is therefore essential as feed. The use of demineralized water also minimises blowdown and conserves energy in these boilers. High quality demineralised water is a critical requirement in the production of steam used

High pressure boilers (Powertherm) are mostly water tube boilers in which water is on the tube side while flue gases flow across the tubes thereby transferring heat from flue gases to water using cross flow heat transfer.. Thermodyne has a vast experience in manufacturing Water Tube Boilers of a wide range of capabilities that suit the customer needs.

In water tube Boiler water flows in tube and Flue gasses flow around the water tubes. As compared to fire tube Boilers, water tube Boilers are used for high pressure application because 1. The heat transfer area is more in water tube boilers as Wa

Silica needs to be controlled at DM plant also. The percentage of impurity allowed in boiler water/steam is function of boiler operating pressure, so, more critical for high pressure boilers. Two basic ways to regulate corrosion in water, are All Volatile Treatment (AVT) and Oxygenated Treatment (OT).

2015-8-20 · As the temperature increases, the solubility of oxygen decreases, but water under pressure can hold higher amounts of dissolved oxygen. Nitrogen, being inert, has little effect on water used in boilers. Water can contain 10 ppm of carbon dioxide, sometimes much more than that due to decaying vegetation and organics in soil.

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.

Types of High Pressure Boilers. A boiler is a vessel in which water is heated under pressure and vaporized into steam for a specific purpose. There are several different kinds of boilers, heated by coal, solid fuel, oil or gas. Boilers vary widely in size from small, portable or shop-assembled units to …

Demineralised water is used in refineries of the sort of power industry, to feed their high-pressure boilers. As high-pressure boilers require higher quality of water sans less contaminants, demineralisation is the solution either by ion exchange or reverse osmosis or nanofiltration or membrane filtration.

Low-pressure boilers will heat a school or office building. A boiler is an appliance designed to heat water and produce energy. The heat is applied to water in an enclosed container before being distributed throughout the system. The major difference between a low-pressure and a high-pressure boiler is the amount of pressure per square inch and
