The low-pressure reaction turbine was a fourth stage of expansion, extracting every ounce of power from the steam supplied from the boilers. The result was an increase in fuel economy and overall horsepower. A simple animation of the combined propulsion system used on Titanic is shown below. This real-time animation models the operation of the

High-pressure steam locomotive - Wikipedia

A high-pressure steam locomotive is a steam locomotive with a boiler that operates at pressures well above what would be considered normal. In the later years of steam, boiler pressures were typically 200 to 250 psi (1.38 to 1.72 MPa).High-pressure locomotives can be considered to start at 350 psi (2.41 MPa), when special construction techniques become necessary, but some had boilers that

Marine Boiler Burner and Combustion - MirMarine

The fuel pressure required for pressure jet burner may vary from 10 bar to 21 bar depending upon the design of the burner and load of the boiler. The maximum required viscosity at the burner inlet is normally 15 cst and both diesel and heavy oils can be used as fuel. Advantages: Robust construction; High Turndown ratio of 4:1

Boiler Operation & Boiler Maintenance | HSB Locomotive

Boiler logs are the best method to assure a boiler is receiving the required attention and provide a continuous record of the boiler's operation, maintenance and testing. Because a boiler's operating conditions change slowly over time, a log is the best way to detect significant changes that may otherwise go unnoticed.

The D-type boiler has been installed in US Navy ships since 1950. Whether 600 psi or 1200 psi, D-type boiler construction is basically the same with a few exceptions, such as number of fuel oil burners and overall size and volume. Fuel oil burners are located on the boiler front and extend into the furnace to provide a means of firing the boiler.

Marine Steam Boilers Heavy Fuel Oil System

On large boilers the fuel oil flow controller gets its setpoint from the burner management system or the airflow controller to achieve a proper air-fuel mixture. On smaller boilers the fuel oil flow control valve often is connected to the combustion air damper by means of a metal rod or wire. In both cases the steam pressure in the boiler sets

Mar 16, 2020 · Boiler or we may also call it a boiler is a closed vessel that can form steam with a pressure greater than the atmosphere by heating the boiler water in it with hot gases from the combustion of fuel. A boiler or steam boiler must be equipped with equipment that can help its performance so that the operational boiler runs safely.

Boiler Energy Efficiency Measures

Boilers and Steam System The steam system plays a major role in energy efficiency of certain ship types (such as steam driven LNG ships) and a medium role in ships such as oil tankers carrying liquid cargo that require cargo heating or there is a need for cargo transfer using steam driven pumps but also need to generate Inert Gas for cargo tank cleaning, purging or tank top ups.
