1 section • 12 lectures • 48m total length

Industrial Boilers Introduction7:46
The lecture introduces a simplified boiler and its major components, including the boiler feedwater pump, deaerator, economizer, steam drum, and superheater, and explains flow control and safety systems.
Superheater9:33
Increase steam temperature and energy for turbines by using a superheater that uses flue gas, examine its advantages and disadvantages, and introduce radiant and convection types.
Economizer2:27
The economizer preheats feedwater before it enters the steam drum to save fuel. It cools flue gas via heat exchange, reducing NOx and boosting boiler efficiency.
Steam drum internals5:24
Discover steam drum internals that separate saturated steam from water with uniform feed water distribution. The system uses CBD lines, openings, cyclones, and scrubbers to produce dry saturated steam.
Introduction, Layout, function of Deaerator and its all auxiliaries2:48
Explain how a deaerator removes oxygen and carbon dioxide and feeds deaerated water to the boiler, detailing the tank, feedwater pump, vents, trays, steam inlet, and safety features.
Mechanical separation vs chemical separation2:45
Explore the two deaeration methods, mechanical separation and chemical injection, showing how sprays and steam scrub water to remove dissolved oxygen and carbon dioxide, with sodium sulfide forming sodium sulfate.
Real life Practical example of pressure and solubility2:19
Observe how increasing pressure raises dissolved carbon dioxide in a cold drink. Depressurizing causes bubbles to escape, while heating lowers the dissolved gas and alters the taste.
Types of Deaerators0:27
Explore the types of deaerators: spray type, tray type, pressurized, and vacuum deaerators, noting the shown unit is a pressurized deaerator with sprays and trays.
Vacuum Deaerator3:32
Operate a vacuum deaerator to remove dissolved gases from feedwater by lowering the partial pressure with a vacuum, using water sprays and optional steam heating, aided by a vacuum ejector.
Efficiency of Dearators1:02
Discover how deaeration controls oxygen in feedwater to seven parts per billion for high-pressure boilers, using mechanical and chemical removal, an oxygen analyzer, and diagnosing pump or spray failures.
Feed water pump cavitation0:48
Increase feedwater temperature to remove dissolved gases, but stay within pressure and temperature limits to prevent cavitation in the boiler feedwater pump, protecting pump integrity and deaerator efficiency.
Furnace and combustion system9:37
Explore the furnace and combustion system, covering air inlet and draft types (forced, induced, balanced, and natural), air preheater and economizer roles, and burner design for complete, stable combustion.

Requirements

To take this course students are required to have different pen colors and a notebook to draw the process flow and take notes of lectures. The notes can also be taken by using "Notes" app or any other similar application by iPhone or android users.
