Package boiler - Wikipedia

Package boiler. Package boilers are used for heating and act as a steam generator for small power purposes such as self-powered industrial plants. They cannot be used for large-scale power plants such as co-generation plants due to their size and lack of efficiency. Advantages of package boilers are that they can be brought in as a whole assembly,

The importance of pH in steam-boiler water - Heating Help

Jun 24, 2014· That oxygen comes out of solution as the water boils, and it can eat holes in the boiler, right at the boiler's waterline. If you decide to feed with hot water instead of cold water, the minerals in the water will come out of solution on the automatic water-feeder's seat, and that can cause a flood, especially if it's a one-pipe-steam system.

What is boiler water PH? And why so maintained? - Quora

Jan 27, 2018· PH control is related to Acidic Corrosion- Low makeup or feed water pH can cause serious acid attack on metal surfaces in the boiler system. Even if the original makeup or feed water pH is not low, feed water can become acidic from contamination of the system. Therefore to prevent acidic corrosion PH is maintained in Alkaline range.

Why Economizer and Air Pre-Heaters are Provided in Boilers

Boilers are provided with economizer and air pre-heaters to recover heat from the flue gases. Boilers operate with around 86 to 90% efficiency depending upon the type of fuel and design adopted. A degrease of about 20 % of boiler efficiency is seen by not providing both economizer and air pre-heaters. If economizer alone is provided then the efficiency will be lower by 12 % when compared to
