Introduction

shengli CWNS Series Oil/Gas Fired Hot Water Boiler series boiler is horizontal three return fire tube hot water boiler. It is equipped with high efficiency burner and advanced techniques. The burning control, water feed, and program run, etc, are full automatic.this boiler is safe and reliable, and also has the advantage of compact structure, simple operation, easy installation, high efficiency, less pollution and noise, etc.
Application

It is widely used for enterprise, factory, hotel, hospital, office building, civil architecture, etc.
Advantage

1. Raw Material

1) To ensure superior raw material supplier, we choose domestic well-known manufacturer who can provide component report of raw material.

2) After the completion of raw material procurement, there are specialized technicians in our factory to make sampling chemical composition analysis and physical performance analysis, and we can also provide raw materials inspection report.

2. Mechanical process

1) Cutting process: We adopt numerical control cutting, which has the advantage of high precision, neat cutting surface, nice appearance and high material utilization. Besides, it can also minimize the effect on material.

2) Welding process and testing process

a. We adopt submerged arc fully automatic welding. Compared to manual welding, automatic welding can ensure high quality of welding seam so as to improve the reliability of the boiler.
b. When each welding process is done, the 100% X-ray inspection will be arranged for every welding seam, which can prevent the defective parts from flowing into the next process.
c. We also adopt plate edge automatic welding. The welding quality is better, welding seam is stronger and the life is longer.
d. Usually, the industry practice is random sampling. But the quality inspection department in our factory conducts a comprehensive quality inspection with 100% X-ray inspection.
e. Our factory quality inspection departments will make a record for everyone who took part in welding process testing and an effective accountability system with signature and seal. If there is a problem of the boiler, personal legal liability can be investigated.

3. Boiler Proper

\1) Corrugated furnace

a. The use of the conical furnace can reduce the impact and scour to the furnace
b. The large size corrugated furnace can improve the duration of the flue gas in the furnace, increase the heat exchange area, make the furnace have better heat transfer effect, and improve the efficiency of the whole boiler.

2) Tube plate and smoke tubes

a. The amount of the slant brace is sufficient to ensure that the tube plate and the drum load are evenly distributed, so as to avoid deformation, protrusion and fracture and improve the overall strength of the boiler.
b. The thread smoke tube can make the flue gas to round move forward and remove impurities at the same time.It can also extend the duration of the flue gas, make the flue gas and smoke tube full contact and raise the heating transfer effect. The steam can be formed in 20 minutes with high quality.
c. The tube plate and smoke tubes are resistant to corrosion, the welding seam between them is fully automatic welding, which can ensure that the smoke is not easy to leak.

3) The front and rear smoke box

a. We adopt the embedded smoke box, which is well sealed and not easy to leak and deform;
b. There is a design of condensation water overflow on the front and rear smoke box. It make the condensation water can be discharged in time and effectively prevent condensation water from coming back into the furnace and corroding the boiler proper;
c. The front and rear smoke box also have divided doors, which has the advantage of good performance and beautiful appearance, and it is easy and convenient to open when maintain.

4) Safety explosion-proof device

a. It is an automatic spring explosion-proof device to prevent deflagrating , and there is an observation hole to check the flame condition.
b. The front and back panels are highly heat insulation with good heat preservation, the temperature is below 40℃, it is safe enough and not easy to burn.


4. Instruments and valves

1) Burner

Usual burner brand: Italy Baltur, Ecoflam, Riello, Unigas ( imported with original packaging)
Germany Weishaupt, Finland Oilon. It is general mechanical proportion adjustment, two-stage fire.
1-5 ton boilers usually use Baltur or Ecoflam burner (imported with original packaging) --one-stage fire, mechanical proportion adjustment
6-10 ton boilers usually use Riello or Unigas burner.
When the capacity is more than 10 ton, we often use Elco or Weishaupt burner----Split type, fully electric proportion adjustment

2) Water pump

Usual brands: Top brands in China
shengli adopts the stainless vertical pump with low noise, stainless impeller and pump body. The pressure of flow and lift is far below the pressure of boiler required.

3) Control system

We adopt Siemens PLC(Programmable Logic Control)and Schneider electrical components
It can realize automatic interlock control of water level, pressure, temperature and feed water with high accuracy Multiple protection can ensure boiler safe operation. It can also realize continuous water supply and frequency water supply constantly and make steam quality to achieve the best effect. If necessary, it can be connected to Ethernet to achieve remote operation.
