Steam Generator and Auxiliary Systems

This specialization provides a detailed understanding of boiler environmental, electrical, and control systems in modern thermal power plants. It begins with the fundamentals of NOx generation and reduction technologies, including primary combustion control measures, Selective Non-Catalytic Reduction (SNCR), and Selective Catalytic Reduction (SCR) systems, along with associated ammonia handling. Learners also explore Flue Gas Desulphurization (FGD) systems, including wet limestone-based FGD, major components, and limestone and gypsum handling systems. The course covers boiler electrical systems, including auxiliary power supply, HT and LT switchgears, motors, variable frequency drives, DC motors, starter panels, and earthing. Dust control systems and Electrostatic Precipitators (ESP) are explained in detail, covering ionization, ash collection, high-voltage equipment, and mechanical safety features. Instrumentation and control topics include pressure, level, flow, and temperature measurement, analysers, final control elements, HART and Foundation Fieldbus, burner control systems, boiler monitoring equipment, control logic, and Distributed Control Systems (DCS). Learners gain the skills to design, operate, and maintain reliable, efficient, and compliant boiler environmental, electrical, and control systems.

This course specialization provides an in-depth and industry-oriented understanding of boiler layout, design, pressure parts, and structural support systems used in thermal power plants. It begins with an overview of boiler plant layout, covering ground-mounted equipment, fuel preparation areas, firing systems, critical piping, fans, ducting, and chimney interfaces. The course explains customer specifications, basic boiler design inputs, heat duty, efficiency, and combustion calculations, along with guidelines for furnace selection, coal pulverizers, and heating surface design. Detailed coverage is given to pressure part arrangements for stoker-fired, fluidized bed, circulating fluidized bed, and pulverized coal–fired boilers. Key components such as economizers, steam drums, water walls, superheaters, reheaters, headers, and desuperheaters are explained with construction and flow paths. The specialization also focuses on boiler supports, buckstays, materials, metallurgy, insulation, refractory, and applicable codes and standards. Structural engineering aspects include boiler structures, platforms, galleries, loadings, analysis, design, and structural connections, enabling learners to understand safe, reliable, and optimized boiler design.

This course specialization delivers an in-depth and practical understanding of boiler major systems, with strong emphasis on fuel preparation, combustion, air–gas–draft systems, and water–steam cycle integration in thermal power plants. It begins with detailed coverage of fuel preparation and firing systems, including fuel oil and coal firing equipment, combustion fundamentals, and soot blower systems. Learners gain clear insight into air and gas flow sequences, draft systems, fans, air preheaters, ducting arrangements, and associated design considerations. The specialization provides comprehensive knowledge of boiler water and steam systems, including supercritical boiler water–steam circuits, condensate and feedwater systems, feedwater heaters, deaerators, boiler feed pumps, condensate extraction pumps, and condenser systems. Power cycle chemical treatment, condensate polishing units, and boiler water quality monitoring systems are also covered to ensure reliable and efficient operation. A major focus is placed on coal milling systems, covering coal bunkers, feeders, pulverizers, vertical roller mills, classifiers, reject handling, coal piping, and temperature and airflow control. The course further explains fan sizing, air preheater construction, duct design, accessories, and applicable codes and standards. This specialization equips learners with a system-level understanding essential for safe, efficient, and optimized boiler and turbine-cycle operation.
