Components of boiler accessories

Boiler accessories are a key component of the boiler, which is conducive to the efficient operation of the boiler. Some key boiler accessories are listed below. Centrifugal pump; heating surface; economic development device.

Centrifugal pump: The centrifugal pump is used to transport water to the boiler. The feed pump can be a centrifugal fan or reciprocating. But the double-effect reciprocating pump is usually used as a centrifugal pump. Heating surface: The heating surface is the key machinery and equipment of a gas-fired steam boiler. Its purpose is to increase the temperature of saturated steam without increasing its working pressure. The heating surface is usually a component of the boiler, and it is placed in a safe passage for hot smoke and dust in the furnace. The calorific value discharged from this type of flue gas is used to saturate the steam. This type of heating surface is installed in the boiler and is called the overall heating surface.

Economic development device: Energy saver is a type of equipment used to heat water supply and drainage by using the calorific value of organic waste gas before leaving the chimney. Improve the rationality of the steam boiler. Below are the advantages of the application economic development device. There are probably 15 to 20% coal savings. It improves the steam lifting capacity of the boiler because it reduces the time required to convert water to steam. It avoids the scaling of boiler water pipes, because the formed scale is easy to clean for saving pipes. Because the water supply and drainage into the boiler is hot, the strain caused by uneven swelling is minimized.

The design scheme of the inspection light and the pivot point is to be used in cooperation with each other, which is convenient to observe all the fuel pipeline leaks in the middle of the casing of the water pipe boiler, or see all the leaks at the hand orifice plate on the steam header. The bet explosion-proof and anti-pollution inspection lights consist of an explosion-proof ball inserted into the outer boiler casing. The ball valve is connected to the inner side of the boiler casing and the aluminum cover, and the aluminum cover is fixed on the casing. Because the lamp holder and the wire are connected to the lamp cover, it can be inspected or replaced from the outside without easily affecting the operation of the burner or boiler, and without reducing the air pressure in the double housing. Boiler grate stove bar. The explosion-proof and anti-fouling window of the licensing board consists of a Pyrex Astri board glass mounted to an aluminum frame and connected to the outside boiler casing. Manhole hand hole. This type of viewport can be used independently or together with the betting boiler inspection light. Boiler inspection lights and pivot points have been approved to be installed on USN and USCG vessels for droplet inspection on boilers.

Regular maintenance of the boiler is necessary to ensure the safety of all machinery, equipment and components, and the normal operation of everything. When the boiler stops running, an appropriate procedure should be selected to reduce welding stress, avoid silt settling and "bake" the water side surface.
