WNS series oil and gas steam boiler adopts shell type full wet back type fire tube structure. The structure adopts three return journeys, in which the oil or gas is well atomized by the burner and fully mixed with the air, and is completely burned in the corrugated furnace bile, and then turns from the rear smoke chamber into the return smoke pipe, turns to the front smoke box into the return smoke pipe, enters the back smoke box, and is discharged by the chimney.The size of the furnace liner we choose is large, which provides conditions for the full combustion of fuel, so this packaged steam boiler can burn heavy oil, light oil, natural gas and city gas. In addition, our company adopts threaded smoke pipe in the design, and the relative flow rate can control low smoke resistance, low power consumption and large load regulation ratio under the guarantee of sufficient heat transfer.
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.
SAFETY FEATURES
