Compared to the composition of air, the diesel exhaust gas contains increased concentrations of water vapor (H 2 O) and carbon dioxide (CO 2)—the main combustion products. The concentrations of both H 2 O and CO 2 can vary from a few percent, up to about 12% in diesel exhaust. These combustion products displace oxygen, the concentration of which can vary from a few percent, up to about 17% (compared to 21% in ambient air).
air and exhaust gas is reduced. The reduction of the intake air amount and the exhaust gas amount results in an increased exhaust gas temperature after the main engine turbocharger(s) and exhaust gas bypass. This means an increase in the maximum obtain-able steam production power for the exhaust gas fired boiler – steam, which
the boiler tubes. We distinguish the following types of exhaust gas boiler fire: small soot fire and high-temperature fire as hydrogen fire and iron fire. Small soot fires in the exhaust gas boiler are localized and occur during manoeuvring or engine low load operation.
Exhaust Gas Boilers And Economisers working procedure The use of exhaust gases from diesel main propulsion engines to generate steam is a means of heat energy recovery and improved plant efficiency.The auxiliary steam installation provided in modern diesel powered tankers usually uses an exhaust gas heat exchanger at the base of the funnel and one or perhaps two watertube boilers ..
- 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 is usually used.
Exhaust gas boilers ; The original exhaust gas boilers or economizers were of simple construction and produced, from the low powered engines of the time, a very moderate amount of steam. As large slow speed engine powers increased, the larger quantity of steam that could be generated from otherwise wasted exhaust energy, ..

Exhaust Gas Boilers also known as Exhaust Gas Economizers, with extended heating surface, used for waste heat recovery in motor ships. A diesel engine loses approximately 30% of the energy to the exhaust gases. A turbocharger recover some of it, but there is still heat losses that can be recovered by means of an Exhaust Gas Boiler, EGB.
Flue Gas Analysis is performed by inserting a probe into the flue of the furnace, boiler, etc., between the last heat exchanger and draft diverter or any source of make-up air that could enter the flue that did not pass through the combustion process. This is known as ‘in-situ’ testing.
With diesel machinery the amount of heat carried away by the exhaust gases varies between 20 to 25 per cent of the total heat energy supplied to the engine. Recovery of some of this heat loss to the extent of 30 to 50 percent is possible by means of an exhaust gas boiler or water heater.
Exhaust gas economizers after diesel engines and waste heat recovery units after gas turbines are unfired and utilize the otherwise wasted heat from the exhaust gas of the diesel engine/gas turbine to produce energy/heating.
Exhaust Gas Boiler Fire causes and actions to be taken in such scenario are discussed in this article. If proper precaution and maintenance is done, such a scenario can be avoided easily.

Hello everybody: In our Diesel power plant it is planned to use the engine exhaust gases to generate energy by cogeneration. For medium speed (514 rpm) twin turbocharged Diesel engines, delivering 17.000 kW, it is required to know the exhaust gas pressure.
What levels of pollutants can a typical wet exhaust gas cleaning system remove from an exhaust stream? How wet is the exhaust gas after scrubbing? If an exhaust gas cleaning system adds or removes CO2 won’t this make the monitoring of emissions to air inaccurate? Do exhaust gas cleaning technologies contribute to increased global CO2 emissions?
An exhaust gas heat exchanger uses the waste heat from combined heat and power units (CHP), usually to generate hot water or to heat thermal oil. Typical fuel gases or liquid fuels for engines include natural gas, biogas, sewage gas, other special gases, diesel or vegetable oils.
Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator. Quite often, the flue gas refers to the combustion exhaust gas produced at power plants .
A flue gas stack or chimney is typically a vertical tubular structure used for ejecting exhaust flue gas to the atmosphere. You can see the chimney or flue gas stack in thermal power plants, diesel gensets, kilns, and many other plants, where gases evolving from the combustion process need to be exhausted.
A cast iron boiler is one in which combustion gases rise through a vertical heat exchanger and out through an exhaust duct. Water in the heat exchanger tubes is heated as it moves upward through the tubes. Cast iron boilers produce low pressure steam or hot water, and generally burn oil or natural gas.
