This course provides in-depth knowledge of boilers operating conditions and constraints for a safe and reliable operation.
Public :
Operators, panel operators, supervisors and plant managers involved in steam production facilities operation and optimization.
Maintenance, instrumentation technicians and supervisors working on boilers.
Level :Skilled
Prerequisite :
To have a 1 month of proven professional experience in the refining or petrochemical industry.
Course Content
BOILER DESCRIPTION & OPERATING CONDITIONS
Different types of boilers and their characteristics. Operating conditions. Fuel consumption. Distribution of the heat supply as a function of the steam pressure and temperature. Construction of the vaporization and superheating tube bundles, the economizer and the drum.
Application: calculation of heat distribution between water wall, superheaters, economizer and air preheater.
COMBUSTION - BURNERS
Combustion conditions: fuel characteristics.
Conventional and low NOx burner technology and operation.
Combustion quality: analysis of oxygen and unburned material in the flue gases.
Safe combustion: flame detection, control and safety devices on the fuel circuits.
Air and flue gas circulation. Flue gas pressure profile in the boiler, draft control.
Application: flue gas composition calculation, air and flue gas pressure profile drawing.
STEAM PRODUCTION
Water preparation: drawbacks arising from the impurities in the water, water quality measurement, characteristics of feed water and water in the boiler, thermal degassing, water chemical conditioning.
Control loop systems: steam pressure, feed water flow rate, superheated steam temperature, disruptions and control principles.
BOILER OPERATION
Steam generation inside tube coil and steam superheating.
On-stream boiler operations: routine monitoring, operating condition changes, analysis of disturbances, soot blowers, drains, etc.
Start-up and shutdown: preparation, ignition procedures, pressure build-up, connection to network, normal or emergency shutdown.
Application: study of start-up and shutdown procedure. Accident case studies.
Learning Objectives
Upon completion of the course, participants will be able to:
operate the boilers safely, while following the rules of optimized combustion, feed-water quality, water and steam control,
describe combustion rules and calculate the air/fuel ratio for optimum combustion,
identify bad-quality combustion from flue gas analysis and flame study and implement corrective actions,
list the main steps of a boiler start-up and shutdown procedure.
Ways & Means
Use of case studies or exercises based on actual cases from the industry.
Special emphasis on safety issues and abnormal situations that can lead to accidents.
