city using a gas-turbine cogeneration plant with a heat recovery steam generator (waste-heat boiler) to raise steam (Figure 3.1). The overall thermal efficiency of such systems can be in the range 70% to 80%; compared with the 30% to 40% obtained from a

uses lower heating value (LHV) or net calorific value (NCV) of the fuel, can also be used to determine the steam generator efficiency. Efficiency calculated on the basis of LHV is higher than the efficiency based on HHV because LHV ignores the heat
2010/11/26 · The steam generated by the boiler can also be use for cleaning, and heating of the seawater in the freshwater generator thus evaporating it to make it potable water. There are two types of boiler mainly use in the Marine Industry, The water-tube boilers and the fire-tube boilers.
