BOILER POWER GENERATION PLANTS INSTALLATION
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 (10.5 kg/cm2 to 14.5 kg/cm2) but, at pressures above this, it is more usual to speak of a steam generator.
A boiler or steam generator is used wherever a source of steam is required. The form and size depends on the application: mobile steam engines such as steam locomotives, portable engines and steam-powered road vehicles typically use a smaller boiler that forms an integral part of the vehicle; stationary steam engines, industrial installations and power stations will usually have a larger separate steam generating facility connected to the point-of-use by piping. A notable exception is the steam-powered fireless locomotive, where separately-generated steam is transferred to a receiver (tank) on the locomotive.
BOILER SAFETY
When water is converted to steam it expands in volume 1,600 times and travels down steam pipes at over 25 m/s. Because of this, steam is a good way of moving energy and heat around a site from a central boiler house to where it is needed, but without the right boiler feed water treatment, a steam-raising plant will suffer from scale formation and corrosion. At best, this increases energy costs and can lead to poor quality steam, reduced efficiency, shorter plant life and an operation which is unreliable. At worst, it can lead to catastrophic failure and loss of life. While variations in standards may exist in different countries, stringent legal, testing, training and certification is applied to try to minimize or prevent such occurrences. Failure modes include:
- Over pressurization of the boiler
- Insufficient water in the boiler causing overheating and vessel failure
- Pressure vessel failure of the boiler due to inadequate construction or maintenance.
We are dealing in all new boilers also we can design the Boiler as per your requirements.

BOILER FITTINGS
- Safety valve: used to relieve pressure and prevent possible explosion of a boiler. As originally devised by Denis Papin it was a dead weight on the end of an arm that was lifted by excess steam pressure. This type of valve was used throughout the 19th century for stationary steam engines, however the vibrations of locomotive engines caused the valves to bounce and “fizzle” wasting steam. They were therefore replaced by various spring-loaded devices.
- Water column: to show the operator the level of fluid in the boiler, a water gauge or water column is provided
- Bottom blowdown valves
- Surface blowdown line
- Feed pump(s)
- Circulating pump
- Check valve or clack valve: a non-return stop valve by which water enters the boiler.

WATER TREATMENT
Feed water for boilers needs to be as pure as possible with a minimum of suspended solids and dissolved impurities which cause corrosion, foaming and water carryover. The most common options for demineralization of boiler feedwater are reverse osmosis (RO) and water softener.
