    Reasons for High Exhast Gas Temperature (EGT) in Marine

    Exhaust gas is by-product of combustion and is naturally at a high temperature. But there is a limit to the diesel engine exhaust gas temperature, and it should not exceed the manufacturer's stated values. Learn what problems can cause this rise in exhaust gas temperature in order to enable troubleshooting and so that taking care of these factors results in restoring normal temperatures.

    In Handbook of Liquefied Natural Gas, 2014. 10.2.13 Gas turbine exhaust duct firing. With duct firing, the gas turbine exhaust temperature can be increased; subsequently increasing the steam production from the steam generator. During high ambient temperatures, the power plant output will drop and may not meet the power requirement of the LNG plant.

    The high heat capacity of the gases (primarily due to the triatomic molecules CO 2 and H 2 O) reduces the peak burned gas temperature, therefore producing a marked reduction in NO. Exhaust gases are retained in the charge both passively (i.e., through incomplete scavenging of the fresh charge) or through active recirculation via an EGR control
