As the main turbine requires superheated steam, most auxiliary turbines require de-superheated steam e.g. main power generators, boiler feed pumps, and cargo pumps on oil tankers.
The steam boiler adopts the three return structure combined with the layout of the economizer and air preheater, recycles large quantity of condensing water during the production process. By making full use of waste heat of condensation water, the boiler still can ensure low exhaust temperature.
Generally, if there are two auxiliary boilers on a ship, they must not run in parallel if one can supply the whole steam demand; unless safety issues dictates the need for such a parallel operation case. Fig (iv): Boiler fuel consumption Boilers and Steam System Overview of a ship’s steam system
auxiliary boiler: An auxiliary boiler, on a steam ship, supplies steam that is not used for main propulsion, but is necessary for some part of the essential machinery. See also donkey boiler. A small boiler may be used as an auxiliary boiler when at sea, or a donkey boiler in port.
Whether it is steam powered or has a diesel engine as the main form of propulsion, a ship without a boiler is really difficult to imagine; a boiler, in one form or another will be found on a ship. For example if a ship is a steam powered ship, two or more boilers will be provided to produce high temperature, high pressure steam.
A steam generator on a ship is an auxiliary boiler which draws high-pressure superheated steam from the vessel's propulsion system to generate low pressure saturated steam. This secondary steam is then used to power auxiliary shipboard engines driving winches or pumps, or to meet any steam requirement that does not require superheating, such as
Proper boiler water treatment eliminates sludge and scale deposits within the boiler. However, over along period of time a film of copper and iron oxides build up on the tube surface. Most of these oxides are transported from oxides of corrosion within the feed system to the boiler with the condensate.
Two groups of feed water valves are provided in the boiler. Each group comprises a shut-off valve and a non-return valve. The shut-off valve in the ordinary group must be open when the boiler is in operation, or if the boiler is used as a steam drum. The shut-off valves should be closed when the boiler is not in use. Water level gauges
Auxiliary boiler. A boiler that supplies steam for essential auxiliary purposes but not for main propulsion.
On ships which are not propelled by steam, gas turbine and diesel ships, for example, some type of boiler is still used to provide hotel service steam.
