Apr 01, 2016 · Fig. 4 illustrates the scatter diagram of the fuel consumption versus speed corrected to design loading condition and the corrected speed. The data present a wide scatter to the average treadline, Fuel Cons = 0.1727 × Speed 2 – 0.217 × Speed, with fuel consumption in tonnes/day and speed in knots, as can also be deducted from the low starting R-square value of 0.7557, and hence it is

Boiler Water Treatment in Marine Boilers - ShipFever

The steam that goes to the main engines, ship's service turbine generators, boiler internal desuperheater and main feed pumps (on certain ships) is called main steam. Steam generation in a conventional steam plant begins with the boiler. The D-type boiler has been installed in US Navy ships since 1950. Whether 600 psi or 1200 psi, D-type boiler

Classification of Marine Boilers and Uses of Steam on Ship

The efficiency of Holt's package of boiler pressure, compound engine and hull design gave a ship that could steam at 10 knots on 20 long tons of coal a day. This fuel consumption was a saving from between 23 and 14 long tons a day, compared to other contemporary steamers.
