WNS series oil/gas boiler body processing equipment advanced, exquisite technology, to ensure the quality of the boiler

The key processing technology of steel plate blanking, ring circle, tube plate drilling and so on adopts advanced NUMERICAL control processing technology, reduces assembly stress, and extends the service life of boiler.

Front and rear smoke box panels are cut by CNC plasma cutting machine, neat and beautiful.

The welding between smoke pipe and tube plate is predilated first to eliminate the gap between the pipe and tube plate, and then the welding process of argon arc automatic welding is adopted to effectively eliminate the stress.

The boiler longitudinal and circular seam welding adopt the advanced submerged arc automatic welding technology to ensure the welding quality.

Boiler Features:

1. The design, production, supervision and inspection of boilers are strictly in accordance with the Safety Supervision Regulations for Steam Boilers, JB/T 10094-2002 General Technical Conditions for Industrial Boilers, and JB/T 1619-2002 Technical Conditions for Boiler Body Manufacturing, so as to ensure long-term safety and stability of boilers.

2, the body for the pot shell type full wet back downstream three return firework tube structure, the flame in the large combustion chamber micro positive pressure combustion, complete extension, low burning heat load, less NOx emission of harmful substances.

3, corrugated furnace and threaded pipe structure, that is, to improve the strength, but also to meet the needs of the heat expansion of each part.

4. Butt joint is adopted in the welding of the main welding seam, and non-destructive inspection is conducted by X-ray and ultrasonic to ensure that the welding quality meets the national requirements.

5, the boiler water volume and gas space is large, strong capacity to adapt to the load.Reasonable design of boiler installation, to ensure that the steam water rate is less than 4%, to meet the higher requirements of users on the quality of steam.

6, the use of new heat insulation material, light weight, less heat loss, good insulation performance.

7. The water level alarm adopts stainless steel as electrode rod and teflon as insulation material.Inserted from the top, not easy to hang dirt, reliable performance, long service life.

8. The front and rear smoke boxes are connected by hinges, which can be easily opened, convenient for maintenance and maintenance.
