Boiler accessories are an indispensable part of the boiler system. They work together to ensure the safe and efficient operation of the boiler. Here are some key knowledge information about boiler accessories:

Safety valve:

Function: The safety valve is an important safety device of the boiler. It is used to automatically release steam or hot water when the internal pressure of the boiler exceeds the set value to prevent the boiler from exploding due to overpressure.
Type: According to the working principle, the safety valve can be divided into spring type, lever type and heavy hammer type.
Importance: The reliability and accuracy of the safety valve are crucial to the safe operation of the boiler.

Water level gauge:

Function: The water level gauge is used to display the height of the water level in the boiler, helping the operator to monitor the water level status of the boiler and ensure that the boiler operates within the normal water level range.
Type: Common types include water glass water level gauge, magnetic flap water level gauge and electrode water level gauge.
Importance: Too low water level may cause the boiler to dry burn, while too high water level may cause steam and water to boil together, affecting the thermal efficiency and safety of the boiler.

Pressure gauge:

Function: The pressure gauge is used to measure the pressure inside the boiler to help the operator understand the working pressure status of the boiler.
Type: spring tube pressure gauge, diaphragm pressure gauge and bellows pressure gauge, etc.
Importance: The accuracy and reliability of the pressure gauge are crucial to the safe operation of the boiler, because it is directly related to the working pressure and load capacity of the boiler.

Drain valve:

Function: The drain valve is used to regularly discharge sewage and sediment at the bottom of the boiler to keep the water quality inside the boiler clean.
Type: According to the structure and working principle, the drain valve can be divided into stop valve, gate valve and ball valve, etc.
Importance: Regular drainage is of great significance to prevent boiler scaling, corrosion and pipe burst and other faults.

Feedwater pump:

Function: The feedwater pump is used to send treated water into the boiler to replenish the water consumed by the boiler during operation.
Type: According to the working principle and structure, the feedwater pump can be divided into centrifugal pump, axial flow pump and mixed flow pump, etc.
Importance: The reliability and stability of the feedwater pump are crucial to the continuous operation of the boiler.

Burner:

Function: The burner is one of the core components of the boiler, which is used to mix fuel and air and send them into the boiler for combustion to generate heat energy.
Type: According to the fuel type, the burner can be divided into oil burner, gas burner and coal burner, etc.
Importance: The performance and efficiency of the burner directly affect the thermal efficiency and emission performance of the boiler.

Pipes and valves:

Function: Pipes and valves are used to connect the various components of the boiler to achieve the transportation and distribution of steam, water and fuel.
Type: Pipes include seamless steel pipes, welded steel pipes and cast iron pipes, etc.; valves include stop valves, gate valves, check valves and regulating valves, etc.
Importance: The reliability and sealing of pipes and valves are of great significance to the safe operation and energy efficiency improvement of boilers.
Understanding the functions, types and importance of boiler accessories will help to better maintain and operate the boiler and ensure the safe and efficient operation of the boiler. At the same time, when selecting and purchasing boiler accessories, attention should also be paid to their quality and performance to meet the actual needs of the boiler.
