Essential knowledge
Operation principle of boiler:
Understand the basic structure and working principle of the boiler, including the combustion system, steam-water system, smoke and air system, etc.
Master the operation procedures of boiler startup, operation, shutdown and accident handling.
Combustion adjustment:Be familiar with the control of the ignition point of coal powder airflow to avoid the impact of premature or late ignition on boiler operation.
Master the adjustment method of the flame center height to ensure uniform temperature distribution in the furnace.
Understand the impact of fuel type and characteristics on the combustion process, as well as the basic principles of air distribution adjustment.
Boiler water level and steam pressure control:Master the adjustment method of the boiler drum water level to ensure that the water level fluctuates within the normal range.
Understand the balance between steam pressure and boiler steam production, external steam consumption, and the impact of steam pressure changes on boiler operation.
Boiler efficiency and heat loss:Be familiar with the calculation method and influencing factors of boiler efficiency, including flue gas heat loss, chemical incomplete combustion heat loss, mechanical incomplete combustion heat loss, etc.
Master the measures and methods to reduce heat loss and improve boiler efficiency.
Boiler accident handling:Understand the types and causes of common boiler accidents, such as furnace coking, water wall tube burst, superheater overheating, etc.
Master the basic principles and emergency measures for accident handling to ensure safe operation of the boiler.
Boiler water quality treatment:Understand the impact of boiler water quality on boiler operation, as well as the importance and methods of water quality treatment.
Master the deoxygenation, softening, and anti-corrosion treatment measures for boiler feed water.
Boiler piping system:Be familiar with the layout and connection methods of the boiler piping system, including feed water pipes, steam pipes, and sewage pipes.
Understand the maintenance and maintenance methods of the piping system, as well as the troubleshooting methods for common faults.
Pipeline introduction
Feed water pipe:The feed water pipe is an important pipe that provides deoxygenated feed water to the boiler.
The pipe is usually equipped with regulating valves, flow meters, pressure gauges and other instruments to monitor and control the feed water volume and water pressure.
Steam pipe:The steam pipe is a pipe that transports steam generated by the boiler to the steam turbine or other steam-using equipment.
The pipes are usually equipped with accessories such as check valves, steam traps, and safety valves to ensure smooth steam delivery and safe use.
Sewage pipe: The sewage pipe is a pipe that discharges sewage and dirt from the bottom of the boiler out of the boiler.
The pipes are usually equipped with accessories such as sewage valves and sewage expansion tanks to reduce noise and heat loss during sewage discharge.
Other pipes: There are other auxiliary pipes in the boiler room, such as fuel pipes, gas pipes, air pipes, etc., which are used to provide fuel and air to the boiler.
In summary, the knowledge and skills that boiler operators need to master are quite extensive, including knowledge of boiler operation principles, combustion adjustments, boiler water level and steam pressure control, boiler efficiency and heat loss, boiler accident handling, boiler water quality treatment, and boiler piping systems. At the same time, they also need to understand the layout, connection methods, maintenance methods, and troubleshooting methods of various piping systems.
