gas turbine ships. The first type is the Conseco
boiler and the second type is the Combustion
In this section we are going to discuss only the
Engineering boiler. Both types of waste-heat
Conseco boiler. This boiler has a three-piece,
boilers operate on the same principle. The
gastight casing, the steam-generating coils or tube
exhaust gases of the SSGTGs are used as the
