Diesel And Gas Boiler Efficiency Measure

Exhaust gas boilers on auxiliary engines - GloMEEP

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.
