Exhaust gas boilers - Ship service systems

Boiler combustion efficiency is the suggestion of burner capability to burn fuel. The burning efficiency depends on two different parameters such as excess O 2 levels in the exhaust and unburnt fuel quantity in the exhaust. The unburnt fuel quantity in the exhaust decreases with an increase in the excess air amount. In addition, this results in dropping the elevating the enthalpy losses with losing the unburnt fuel.

What is Boiler Efficiency? Boiler - Thermodyne Boilers

Flue gas recirculation, or FGR, is the most effective method of reducing NOx emission from industrial boilers with inputs below 100 MMBtu/hr. FGR entails recirculating a portion of relatively cool exhaust gases back into the combustion process in order to lower the …

Boiler Efficiency | How to balance steam loads efficiently

Exhaust gas boilers recover the heat from the exhaust gas of auxiliary diesel engines to generate steam and/or hot water, or useful heat for process heating. Depending on system design, these boilers can enhance the efficiency of the auxiliary engine system by up to 20%, leading to lower overall process costs. See Figure 1.

Exhaust Gas Boilers And Economisers for Marine Machinery

The Exhaust gas economiser in a ship is like a huge heat exchange that exchanges heat between exhaust gas from engines to water and produces steam for the same purpose that auxiliary boilers produce steam. Occasionally use of fuel additives may improve the cleanliness of the economiser . The practice of operating an exhaust gas boiler
