Propulsion boilers are boilers which provide steam for propulsion turbines, and propel the ship through the water by way of reduction gears, shafting, and propeller. There are two basic configurations for propulsion boilers used today on naval vessels, the 1200 psig D-type and the 600 psig D-type.
Aug 09, 2016 · Efficiency of steam power plant. The power plant that operates on coal constitutes almost 41% of the world’s electricity generation. It is the modified Rankine thermodynamic cycle on which the coal fired power plant operates.
A "Scotch" marine boiler is a design of steam boiler best known for its use on ships. Sectional diagram of a "wet back" boiler The general layout is that of a squat horizontal cylinder. One or more large cylindrical furnaces are in the lower part of the boiler shell. Above this are many small-diameter fire-tubes. Gases and smoke from the furnace pass to the back of the boiler, then return through the small tubes and up and out of the chimney. The ends of these multiple tubes are capped by a smok
There are a number of technical terms used in connection with steam generation. Some . of these commonly used terms you should know are as follows: Degree is defined as a measure of heat intensity. Temperature is defined as a measure in degrees of sensible heat. The term sensible heat refers to heat that can be measured with a thermometer.
The main reason for the adoption of this design of boilers is to allow use of modern high efficiency watertube boilers without fear of damage through contamination by cargo or fuel oils. The basic design consists of a D-Type boiler design upon which is mounted a Steam/Steam generator drum.
