Fundamentals of marine boilers and consumption process is a free online course that begins by introducing you to the important terms of the safety valve, the relief valves. Learn about the characteristics of the spring-loaded relief valve, boiler safety valve classifications, and the various categories of the spring-loaded valves. The course will also introduce you to the improved high-lift safety valve for boiler pressure up to 25bars, an illustration of how the higher lift can be achieved. The course will discuss the working of the improved high lift safety valve, and the valve parts involved in the improvement and higher lift. This course will also outline the features of the highest quality borosilicate glass which involves tempering for improved toughness against shattering, as well as an illustration of the reflex-type gauge glass assembly in marine boilers. The maintenance of the safety valves, the procedure of setting a safety valve of improved high-lift type, and the illustration of the sectional view of a gagging arrangement, will be discussed. The waste-steam pipe arrangement, and the operations of the remote-control easing gear will be covered in this course.
The course then explains the different types of directly mounted boiler water level indicators, reflex level gauge, prismatic water gage glasses, and how boiler refractories can be classified.
You will learn about the characteristics of the fireclay, silica brick, magnesite, chromite, chrome-magnesite refractories. You will learn about the operation of the soot blowers, and the soot blowers for high-pressure boilers. The fundamentals of marine boilers and consumption process, along with the operational principle of the diamond retractable soot blower will be taught. The course will then teach you about gear train schematic component description, the high-pressure boiler design, including the challenges, and the illustration of the natural circulation circuit including the primary steam separator in the drum. This course will teach how the steam plant schematics identifies the cycle of the water/steam as fluid around the plant, and how it helps when considering losses preventing the utilization of 100% of the fuel heater. This course explains the effect of density and heat distribution related to steam conditions, as well as the importance of the waste recovery system. The constructional features of the composite boilers, the boiler thermal efficiency, including the heat transfer challenges, and the application of the reheat boilers will also be covered in this course.
Furthermore, this course will help you get familiar with the examination of the exhaust gas economizer, the characteristics of the air heaters, and how the LJUNGSTROM works. The course will discuss the air heater rotor seals, and the main fuel system. This course also highlights the combustion process in the air heater, the steam atomization concepts, the sprayer plate concepts in the boiler consumption process. The distance piece concepts, and the diffuser concepts in the boiler consumption process will be discussed. This course will improve your understanding of how the economizer can work as a multi-pass heat exchanger that can be located above the main generating bank at the exhaust stack. In order for the combustion gas to give up a lot of its remaining heat to the incoming feedwater before passing out the funnel via the air heater. You will learn about the constituents of the boiler fuel oil that take part in a combustion process, how the fuel and air are mixed in a boiler, as well as the concept of primary and secondary flame or suspended flame for stable combustion. This free online course will be of great interest to students, researchers, and anyone with an interest in the boilers in the marine industry.
