Answer: Answer: There are different types of composite boilers. Normally one part of the boiler is heated by means of a fuel oil burner and the other part is heated by the exhaust gases from a diesel engine. Heating of one part of a boiler at the time often causes thermal stress that may lead to leakage.
Auxiliary Equipment Effective and efficient boiler operation requires the use of auxiliary steam plant equipment. For some projects, users can pipe their existing auxiliary steam plant equipment to the new or rental boiler for safe operation. In other cases, new or rental auxiliary steam plant equipment may be required.
The main two basic boilers are: Water tube boiler ; Fire tube boiler ; The design and arrangement of both the types is just the opposite. In water tube boilers, the feed water passes through the tubes and the hot gases are made to pass over them, while in fire tube boilers, the hot gases passes through the tubes and the feed water surrounds them.
A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

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 boiler feedwater and freshwater evaporators .
Economists use this energy in the flue gas to save energy by increasing the temperature of the water/air used in the boiler or anywhere in the business. Depending on the boiler flue gas outlet temperature and the fuel type, the efficiency of the boiler or plant is increased between 3% and 8,5%.
