Product Introduction

Oil (gas) steam boiler, hot water boiler

The WNS gas boiler is a horizontal fast loading internal combustion three return fire tube steam boiler Adopting a bias furnace bladder wet back structure, high-temperature flue gas sequentially flushes the second and third return flue pipes, and then is discharged into the atmosphere through the chimney from the rear flue chamber The boiler is equipped with movable front and rear smoke box covers, making boiler maintenance convenient The boiler is equipped with a burner with excellent technical performance, and adopts advanced technologies such as automatic proportional adjustment of combustion, automatic adjustment of feedwater, program start stop, and fully automatic operation. It also has high and low water level alarms and automatic protection functions such as extremely low water level, ultra-high steam pressure, and shutdown This type of boiler has the characteristics of compact structure, safety and reliability, easy operation, rapid installation, low pollution, low noise, and high efficiency

1. The design, production, manufacturing, supervision and inspection of boilers are strictly carried out 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 Manufacturing Shell Boiler Bodies" to ensure the long-term safe and stable operation of boilers.

2. The main body is a pot shell type fully wet back flow three-way smoke tube structure. The flame burns under slight positive pressure in a large combustion chamber, fully extending, with low combustion heat load and low emissions of harmful substances such as NOx.

3. The structure of the waveform furnace liner and threaded smoke tube not only improves strength, but also meets the needs of thermal expansion in various parts.

4. The main welds are all connected by butt joints and undergo X-ray and ultrasonic non-destructive testing to ensure that the welding quality meets national requirements.

5. The boiler has a large water volume and gas space, and has strong adaptability to load. Design a reasonable pot device to ensure that the water carrying rate of steam is less than 4%, meeting the high requirements of users for steam quality.

6. Adopting a new type of thermal insulation material, it is lightweight, has less heat loss, and has good insulation performance.

7. The water level alarm uses stainless steel as the electrode rod and polytetrafluoroethylene as the insulation material. Inserted from above, it is not easy to get dirty, reliable in performance, and has a long service life.

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

9. Oxygen content regulation (optional): This system can successfully monitor the oxygen content in the flue gas and transmit the data in real time to the control system. Through computer intelligent analysis, it automatically adjusts the ratio of the combustion equipment to make it in the best working condition in real time, greatly improving the combustion efficiency and significantly reducing fuel consumption.
