Apr 19, 2021 · Boiler types. The watertube boiler is employed for high-pressure, high-temperature, high-capacity steam applications, e.g. providing steam for main propulsion turbines or cargo pump turbines. Firetube boilers are used for auxiliary purposes to provide smaller quantities of low-pressure steam on diesel engine powered ships.
High-pressure boiler: The pressure of the boiler above 80 bar. Medium-pressure boiler: It has a working pressure of steam from 20 bar to 80 bar. It is used for power generation or process heating. Low-pressure boiler: This type of boiler produces steam at 15-20 bar pressure…
Jul 18, 2020 · Exhaust Gas Economizer on Ships is a feed-water heater in which the heat from waste gases are recovered.It raises the temperature of feed-water supplied to the marine boiler. Purpose of Exhaust Gas Economiser on Ships. The purpose of the exhaust gas economizer is to increase plant efficiency by removing heat that would otherwise be lost in the flue gas and use it to indirectly heat the
Exhaust Muffler, Exhaust Pipe Exhaust Gas Boiler, Steam Boiler, Hot Water Boiler Factory Provide Marine Boiler Exhaust Gas Economizer Pin Tube Seamless Steel Pipe Finned Tube with ABS BV CCS Dnv. Gl and CCS Certificate.
The revered energy and amount of steam generate by exhaust gas economiser is normally sufficient for routine ship-board steam requirements, thus normally a ship with exhaust gas economiser does not need to fire the boiler while in passage. As far as improving efficiency by avoiding the fouling on the gas side and water side, the same principles
HV Series vent silencers effectively silence high-velocity air, steam and gas vents, as well as blowdowns to atmospheres in which sonic or critical flow conditions exist in the valve. Typical pressure relief applications include steam boiler, super-heat headers, boiler startup and high-pressure purge air vents, natural gas blowdown, switch

7. Stack Size – Pressure drops through the boiler exhaust system should be calculated and in general should not exceed 0.2″ WC. Undersized stacks create excess back pressure on the boiler resulting in combustion problems, inability to make full capacity, or both. There are several very competent manufacturers of boiler exhaust systems.
Provides a lower cost alternative to silencing objectionable noise created by steam exhaust outlets during boiler start-ups and testing stages only. Replacement elements available to make the muffler ready for the next start-up or tuning job. Constructed of corrosion-resistant materials. End caps treated with a special epoxy coating for additional resistance in high-alkali conditions.

Sep 03, 2021 · Feed water heaters, and exhaust duct. Most feed water heaters are located close to the boiler and in the exhaust system duct. Other feed water heaters can be in the engine exhaust steam pipe. I have used both in unison and singularly. Feed waters in the exhaust duct just above the boiler have the h
Boiler Steam Exhaust Silencer control sound through a reactive-absorptive process, which provides good attenuation across all octave frequency bands. 2. Features (1). Eliminate the noise of the exhaust when the equipment is working and at the same time extinguish the spark remaining in the exhaust pipe. (2). Reasonable size, low cost and long lifetime.
The first Aalborg boiler (Scotch marine type) is designed and produced at Aalborg Shipyard, Denmark. In the 1960s, the number of boilers for shipyards around Europe increases. During this decade, the unique combined oil and exhaust gas boiler is designed and introduced to the market. In 1998, the first large oil-fired boiler MISSION OL is
- Exhaust gas boiler, economiser – An exhaust gas heat exchanger is a row of tube banks circulted by feed water over which the exhaust gases from main diesel engine flow. A boiler drum is required for steam generation and separation to take place. For this purpose, the drum of an auxiliary boiler …
Vertical smoke tube exhaust gas boiler resp. economiser; Fulfils partly the function of a silencer in the exhaust gas system. Own steam space and therefore it works independently from other boilers in the system. Has to be connected to a fired boiler or a separate steam drum by means of forced circulation. Suitable for dry running in emergency case
