    Composite Boilers - marineengineeringonline

    Double pass composite boilers, i.e., two passes for the exhaust gases and two uptakes, one for the oil fired system and one for the exhaust system. Double pass exhaust gas, no oil fired furnace and a single uptake. Double pass alternatively fired, two passes from the furnace for either exhaust gases or oil fired system with one common uptake.

    Exhaust Gas Boilers And Economisers working procedure

    Exhaust Gas Boilers And Economisers Arrangement Auxiliary boilers on diesel main propulsion ships, other than tankers, are usually of composite form, enabling steam generation using oil firing or the exhaust gases from the diesel engine. With this arrangement the boiler acts as the heat exchanger and raises steam in its own drum.

    Jun 08, 2019 · 1 Answer. A composite boiler is a specially designed boiler that can use more that one means to pass hot flue gases from different sources to generate steam. For example a boiler that can be fired directly using its in-built furnace and other means to pass hot exhaust gases from a gas turbine or large Diesel engines through the same boiler to generate steam, that type of boiler is a composite boiler.

    The Difference Between Different Types Of Boilers

    A condensing boiler manages to capture more of the fuel’s energy with a larger or secondary heat exchanger. The exhaust gas from a standard regular boiler contains a lot of heat that is simply wasted. A condensing boiler converts this gas into a liquid concentrate and uses a heat exchanger to capture it.
