May 26, 2021 · Marine Boilers are one of the most important machinery onboard a ship. It is a device which produces steam for main propulsion or for auxiliary machinery. To be precise, it is a closed vessel containing water or other liquid which is heated to produce steam which can also be used for cleaning, and heating of the sea water in the fresh water Get Price
Aug 27, 2015 · Boiler Uptake Fire and Exhaust Gas Economiser Fire. Auxiliary boiler uptake or flue gases normally pass through economisers or air pre-heaters or feed water heaters. All these types of heat exchangers are fin type. Hence large amount of carbon or soot deposits on the fins. Along with the flue gases some un-burnt carbon particles also get Get Price
Feb 24, 2012 · Boiler economizer is a device that uses a portion this remained energy of the flue gas to heat up inlet water (feed water) to the boiler. Since the heat energy is given to the water before it gets fed to the boiler, the requirement of fuel for producing steam is optimized. Because of that, we call this device as an economizer.Get Price

The economiser is a heat exchanger through which the feedwater is pumped. The feedwater thus arrives in the boiler at a higher temperature than would be the case if no economiser was fitted. Less energy is then required to raise the steam. Alternatively, if the same quantity of energy is supplied, then more steam is raised.Get Price
