Jul 31, 2013· Two boilers were installed in each fire room. Each of the two stacks served a pair of boilers. The boilers were of the divided furnace or “M” type with separate furnaces for control of steam pressure and temperature (superheat). These boilers were used on nearly all World War II era carriers, battleships, cruisers, and destroyers.

Turbine deposits can accumulate in a very short time when steam purity is poor. The turbine shown in Figure 18-2 was forced off-line by deposition only 3 months after it was placed in operation. Carryover of boiler water, resulting from inadequate steam-water separation equipment in the boiler, caused this turbine deposit problem.

Catalog of CHP Technologies, Section 4. Technology .

Steam turbines differ from reciprocating engines, internal combustion engines, and gas turbines in that the fuel is burned in a piece of equipment, the boiler, which is separate from the power generation equipment. The energy is transferred from the boiler to the steam turbine generator by an intermediate medium, typically steam under pressure.
