The high pressure boiler which is also known as modern boilers used for power generation are for steam capacities 30 to 650 tons/hr and above with a pressure up to 160 bar and maximum steam temperature of about 540°C.
A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation.

The blowdown amount required is a function of boiler type, steam pressure, chemical treatment program, and feedwater quality. The optimum blowdown amount is typically calculated and controlled by measuring the conductivity of the boiler feedwater. Conductivity is a viable indicator of the overall total dissolved solid concentrations. Typically, blowdown rates range from 4 – 8 percent of
* water converted into high pressure steam by transfer of heat from very high temperature combustion gases on water. * hot combustion gases produced by burning diesel oil, town gas etc. in the furnace. * boilers are of fully automatic design. * essential mountings include safety valve, steam pressure switch, pressure gauge, gauge glass, valve fittings, low-water level cut-off and alarm devices
Boilers that operate higher than 15 psig are called “high-pressure” boilers. A hot water boiler, strictly speaking, is not a boiler. It is a fuel-fired hot water heater. Because of its similarities in many ways to a steam boiler, the term ”hot water boiler” is used. Hotwater boilers that have temperatures above 250° Fahrenheit or pressures higher than 160 psig are called ”high temperature

Industrial boiler systems can cope with much higher pressures than pressure cookers. These boilers are welded from thick steel plates that are up to 35 mm thick, making pressures of 30 bar and more possible. A stable, robust design is also essential – if a boiler of this type were to collapse, explosive forces comparable to the explosive power of a ton of gelignite would be released (milk
Boilers are classified by their pressure capacity, their design type and by their use. High & Low Pressure Boilers – The M.A.W.P or Maximum Allowable Working Pressure is the highest amount of pressure that the vessel is designed to withstand. Pressure is measured in terms of pounds per square inch or psi. Psig (gauge) indicates gauge pressure, which ignores the atmospheric pressure. Psia

I of the ASME Boiler and Pressure Vessel Code.2 These rules apply to steam boilers that operate above 15 psig and hot water boilers that operate above 160 psig or 250°F. Common design pressures are 150, 200, 250, and 300 psig, but higher pressures are possible. 3 For example, boilers for certain pulp and paper industry applications are now designed for pressures as high as 1,500 psig
There are two main types of boilers, based on the type of heat transfer system they use: Firetube boilers – store water in the main body of the boiler. They heat the water via conduction where a tube carrying the combustion gases is immersed in water. Firetube boilers are simple and low cost and best suited to producing hot water or low pressure steam. Watertube boilers – Combust fuel in a
High efficiency – High-pressure boilers have better firing methods, monitoring, furnace conditions, control flue gases and water velocity. Intensive heating – the furnace temperature in high-pressure boilers is high enough and therefore, 70% of heat is transferred to water by radiation.

High Pressure Boilers Fire tube boilers are cheaper and easier to transport at low operating pressures (<30bar) and steam generation rates less than 30000kg/hr. Above these parameters, the size of the shell becomes unwieldy to transport.
BOILER TYPES Two principal types of boilers are used for industrial applications: This is a contamination of steam with boiler water solids High concentrations of soluble or insoluble solids in boiler water can stabilize and strengthen the bubbles surface in boiler water, giving rise to foaming. Steam generated can carry the foams into the process. Substances such as oil, alkali, greases
