Three-drum boilers are a class of water-tube boiler used to generate steam, typically to power ships. They are compact and of high evaporative power, factors that encourage this use. Other boiler designs may be more efficient, although bulkier, and so the three-drum pattern was rare as a land-based stationary boiler.
Steam and hot water play an integral role at several stages of the textile manufacturing process. Much of the manufacturing process requires the use of steam or hot water produced by industrial boilers, textile engineering, bulk fabric production, garment manufacturing, or other textile processes.
Pre-treatment
There are several steps in this process, and some of them require both steam and hot water that is clean and pure, which requires an efficient steam boiler.

While the exact chemical treatment plan will be determined by a local water expert after performing an analysis of a water sample, there are some chemicals that are commonly used to treat boiler water.
Establishing a boiler water treatment plan will provide you with real-time feedback of your boiler system so you can get ahead of any issues that might occur as a result of poor water quality. We broke down the boiler water treatment process into three simple steps that you can incorporate into your preventative maintenance practices.
Water quality is of the utmost importance in proper and safe boiler operations. An improperly treated feedwater system can result in the scaling of the boiler internals, safety equipment and auxiliary piping.
The construction and working principle of the boiler economizer is simple. At the bottom part, it has a horizontal inlet pipe through which we feed water with normal temperature to the economizer. There is another horizontal pipe fitted at the top of the economizer.
Steam boilers use a contained heat system to generate steam. The steam travels through pipes in the building’s walls where they emerge at radiators in heating systems. The radiators warm from the steam’s heat. As the steam gives off its heat, it condenses back to liquid water and returns to the tank. A boiler system of this type that does not allow outside water sources is a closed system and is highly efficient for using all the condensed water. An open network may be required in operations where the steam or water gets contaminated in such a way that it cannot return to the boiler for reuse.
A condensing boiler can condense the water vapour in the flue gases and withstand the corrosive and acidic qualities of the flue gas condensate. Although most boilers can condense the flue gasses, only boilers that have heat exchangers constructed from materials able to withstand the corrosion should be used in condensing application. Condensing boilers with primary and secondary heat exchanger do not work well as they are not able to fully condense and defeat the purpose of using a condensing boiler. Also, boilers with this arrangement are prone to condensation in the primary heat exchanger at lower firing rate which can cause damage to the heat exchanger.
