Introduction to Steam Theories in Marine Boilers

This free online engineering course explains the internal workings and use of marine boilers in steam production.

Publisher: ADU
This free online engineering course takes you inside marine boilers as we examine their components to see how they produce steam. We examine ‘D-type’ boilers, the function of various components, boiler mountings and the combination of important modes of steam engine heat transfer. Steam once drove the Industrial Revolution and remains an important source of energy so sign up to improve your understanding of its thermodynamic cycles.

This free online engineering course begins by introducing you to the use of high-pressure boilers to run main propulsion turbines. We take you through the replacement of high-pressure boilers with the new combined-cycle plants that utilize the flexibility of diesel and steam plants. We cover the application of steam theory, heat transfer, properties of the involved fluid, boiler features and the steam engine’s thermodynamic cycle. The course also introduces you to the technical terms that are used in the context of steam generation, the components and properties of the relevant fluid and the combination of the modes of heat transfer. We discuss the advantages offered by steam plants to provide an accurate perspective of steam’s place in global power generation. We then outline the principles of steam generation and boiler design while identifying categories of boilers and popular boilermakers.

This course then demonstrates how the marine boiler is optimized for producing steam before examining water-tube boilers and the theory of heat transfer inside them. We show you the advantages of water-tube boilers over their smoke-tube counterparts and look inside steam drums. We lay out the characteristics of ‘D-type’ boilers before delving into the working principles and design of the double-evaporation Aalborg boiler. Then comes the Foster Wheeler ‘D-4’ type boiler and the screen tubes. We compare the construction and operation of different boilers, including their steam temperature control systems: subcritical and supercritical power plants, main steam-stop valves and the feed-check valve. The course unpacks the operation of boiler mountings and the ‘feed regulatory’ system.

We then compare ‘subcritical’ and ‘supercritical’ power plants and examine various types of once-through boilers. We describe the components and mountings of ‘D-type’ boilers while analyzing the stop and feed check valve. This course explains the feed regulatory system that can be used in steam boilers of a low system and how to monitor the movement of the float. We provide examples of a float control application and unpack water-level control in high-pressure systems, including safety and relief valves and their maintenance. This free online engineering suits aspiring engineers or anyone with an interest in marine boilers and their important role in creating energy.
