Zhongding WNS series natural gas fire tube steam boiler is jointly designed by Xi’an Jiao Tong University, it is a kind of safe and high efficiency heating equipment with full automatic control system. It adopts the national patent technology, optimizes the design of oil gas fired boiler, to achieve a more reasonable combustion chamber and heating area, the thermal efficiency increases more than 10% compare with the ordinary boiler. The boiler is equipped with explosion proof equipment at the back of boiler, prevent deflagration in furnace, discharge high energy, and automatic reset as well, to ensure the boiler operate safety and efficiently.
This series natural gas steam fired boiler is horizontal type fast assembly fire tube boiler with three pass structure, it has compact structure, small volume, strong load adaptability and low water quality requirement. This boiler adopts wet wet back structure, it can adapt to the high temperature, has a good sealing, increase the radiation heat transfer area and improve the heat transfer efficiency.
WNS series natural gas fire tube steam boiler is widely used for industry production and processing, such as textile mill, medicine industry, food & beverage industry, chemical industry, garment industry, food processing industry, and wood processing industry, moreover, it could be used for central heating in enterprise, hotel, hospital, civil architecture, etc.
1. Boiler Customization
Zhongding Boiler owns a mature R&D and design team, and cooperates with multiple scientific research institutions for a long time, i.e. Tsinghua University and Xi’an Jiaotong University. Zhongding Boiler could customize the boiler based on the requirement of customers, water quality and fuel characteristics, to meet the operating requirement and maximum the boilers’ effectiveness.
2. High Quality
1) Burner ---- Customer could designate the brand
2) Electric Control Cabinet ---- Customers could choose PLC or touch screen control cabinet, also, the brand of electric elements could be designated.
3) Water Pump ---- Customer could designate the brand, and the boiler could adopt variable frequency water supply, save energy and decrease operation cost.
4) Economizer ---- The boiler could equipped with economizer based on customers’ requirement, to improve boiler thermal efficiency.
5) Water Treatment Equipment ---- Based on the water quality, could equipped with different water treatment equipment, generally, there are soften water treatment and reverse osmosis water treatment equipment.
6) Boiler Shell color ---- Customer could designate the color of boiler shell, elegant appearance.
3. Advanced Technology and Structure
4. Professional Installation and After-sale Team
1) Zhongding Boiler owns a professional design engineer team, before manufacturing, every boiler design drawing will be approved by boiler and pressure vessel experts of CSBTS ( State Bureau of Quality Technical Supervision ), and then the boiler could be produced only if qualified.
2) To ensure the raw materials quality, all the steel plates are special-used for boiler with the Inspection Certificates. The raw material materials are inspected when entering factory, and only the qualified material could be put in storage and used for production.
3) To ensure the welding quality, there a professional welding team, including more than 30 senior welders. The welding materials are stored under constant temperature and humidity, to ensure the welding material quality.
4) Nondestructive testing will be done to ensure the welding quality, by using x-ray detection, ultrasonic flaw detection, magnetic test, or penetration test, etc.
5) Hydrostatic test will be done to ensure the leakproofness and strength of boiler pressure parts, generally, the testing pressure is 12.5 times of rated working pressure.
6) All the raw materials and boilers are supervised and inspected by the experts of Inspection Institution for Boiler and Pressure Vessel. There are international quality certificates of ISO 9001 and CE, we can also offer the inspection report of SGS, BV, etc., Quality Certificates, Energy audit report, and Energy Efficiency Test Report, etc.
1) Professional engineer installation team offer the door to door installation and after sale service. The boilers will operate smoothly and safety, and you will get them without worries.
5. Convenient Maintenance
2) 24 hours hot-line to solve your problems, and offer the professional technical supports and after sale service in time to all over the world.
1) There are manhole, head hole, and special hand hole on the boiler, and the front and back smoke chambers are equipped with movable doors, which are convenient for boiler internal installation, inspection and clean.
2) The explosion proof equipment has the fire sight glass and inspection gallery, it is convenient for furnace checking and maintaining.
WNS series oil gas fired boiler adopts the advanced horizontal type internal combustion three pass structure, decrease the temperature of exhaust smoke, improve the heat utilization efficiency and thermal efficiency.
