Shangneng CWNS type horizontal oil-fired gas boiler introduction

The CWNS horizontal oil-fired gas boiler produced by Zhejiang Shangneng Boiler Co., Ltd. is a shell type internal combustion three-return all-wet back fire tube boiler designed and produced by our company according to advanced technology and experience at home and abroad, which can both fuel and gas in the principle of steam boiler. The wet back structure of offset furnace is adopted, and the high temperature flue gas successively washes the second and third return flue gas pipes, and then the gas hot water boiler is discharged into the atmosphere through the chimney from the rear flue gas chamber. The boiler is equipped with movable front and rear smokebox covers to facilitate boiler maintenance.

The boiler is equipped with burners with good technical performance, and adopts advanced technologies such as automatic proportional adjustment of combustion, automatic adjustment of water supply, program start and stop, and automatic operation, and has automatic protection functions such as low water level alarm and ultra-high temperature and flame out.

1. Efficient and green

CWNS type atmospheric pressure boiler has the advantages of full combustion, pollution-free discharge, convenient operation, convenient installation, etc. High thermal efficiency, large output, strong load adaptability, high degree of automation, easy operation, safe and reliable operation; The self-developed internal and external thread heat exchange tube bundle structure increases the heat exchange area and heat transfer coefficient, and improves the heat transfer efficiency between water and heat medium water. The wet-back three-return chamber combustion structure is adopted, and the smoke pipe adopts internal and external double thread winding finned tube, which greatly reduces the smoke exhaust temperature of the boiler, so that the smoke exhaust temperature is between 120℃ and 10℃. The thermal efficiency of the boiler is 92%.

This is a high efficiency, low consumption, low pollution green products.

2. Can use fuel diversification

CWNS boiler can use a variety of fuels: applicable fuels are light diesel, heavy oil, natural gas, pipeline gas, liquefied gas, biogas, special flammable harmful gases, etc.

3. Low cost

Less investment, low operating costs: no need to prepare any dust removal and other auxiliary equipment, occupy less land, save capital investment costs, no need to large area of oil storage and storage site, efficient output, saving operating costs; Organic combination of mechanical and electrical integration appearance, ingenious novel, compact structure, less space, convenient transportation, installation. The boiler water supply equipment is arranged on the boiler base on the right side of the boiler so that it is integrated with the main engine, and there is no need to make another foundation.

4. Wide range of application

CWNS boiler can be arranged inside or outside the building to provide central heating, widely used in central heating residential areas, hotels, commercial buildings, colleges and universities, banks, large and medium-sized offices and clean villa communities; Also swimming pool, sanitary water, machinery and mining enterprises process with hot water.

5. Easy maintenance, reliable installation

CWNS boiler supporting all kinds of imported famous brand burners, such as Weisol, Oilon, Riyalu, Black and Green, Liwei, etc., using automatic proportional regulation, atomization methods such as pressure atomization, low pressure air atomization, rotary cup atomization, can be configured according to user needs dual fuel burner, both fuel and gas. Automatic combustion regulation, ensure full combustion, reduce pollution. The front and rear smoke boxes are movable structures. The manhole is connected with flange, which is convenient for inspection, maintenance and cleaning inside the boiler. Boiler factory, compact structure, easy to install, shorten the installation period.

6. Advanced control system

Automatic control, simple operation interface. It has the protection function of over temperature, water shortage, overload, abnormal flameout, gas pressure and gas leakage. The port for remote monitoring is reserved.

7. One machine multi-purpose (indirect)

Each boiler can be configured with multiple heat exchangers to meet the needs of different applications.
