Product Description
Horizontal oil-fired gas steam boiler


Jiangsu Weifu Special Equipment Co.Ltd. is located at Tieta Road, Guyang Town, Dantu District, Zhenjiang City.The company is committed to integrating boiler marketing resources throughout mainland China, and through the marketing network, it conveys the concept, quality, price, and service of Weifu (oil, gas, electricity) boilers to customers. The company follows the concept of "being a real person and doing things honestly", making fine products and warming the world. The company advocates that in the process of Weifu boiler market operation, customers get value, employees get improvement, shareholders get benefits, companies get development, and the country gets tax revenue.
The company currently has more than 200 employees, including more than 40 professional technicians of various types. The company has more than 20, 000 square meters of modern factory buildings and advanced manufacturing and testing equipment, specializing in the design and manufacture of gas (oil, electricity) hot water boilers, gas (oil, electricity) steam boilers, gas (oil, electricity) vacuum hot water boilers, and gas (oil, electricity) organic carrier boilers.
The company follows the business philosophy of "what customers need is what we make", takes boiler products as the main product, and has developed vertical/horizontal gas (oil) steam boilers, vertical gas (oil) normal pressure/pressure hot water boilers, horizontal gas (oil) steam boilers, horizontal gas (oil) normal pressure/pressure hot water boilers, electric heating steam boilers, electric heating normal pressure hot water boilers, gas (oil) thermal oil boiler series products, a total of 7 series and nearly 300 specifications. The company′s products all adopt clean combustion technology. The horizontal pressure boiler body design adopts advanced structures such as corrugated furnace, conical furnace, threaded smoke pipe, wet back three-pass, etc. The boiler main engine is equipped with imported burners such as Riello, Aucma, Black & Decker, and Weishaupt, achieving the effect of high efficiency, energy saving and environmental protection of the boiler. The boiler is equipped with pressure or normal pressure economizers and condensers to further reduce the boiler exhaust temperature, while reducing the concentration of dust, nitrogen oxides and sulfur oxides in the flue gas, making the boiler more energy-saving and more environmentally friendly. Weifu Boiler has become a national supplier of small and medium-sized oil (gas, electric) boilers in China. Its customers are located in large and medium-sized cities in mainland China. It has contributed to environmental protection and energy conservation in mainland China.
The company Holds a national Class B manufacturing certificate,Facing the boiler market where opportunities and challenges coexist, Weifu Boiler adheres to the principle of "creativity for development, credit for cooperation, quality for market share". We will share the value of Weifu Boiler with you.

Burner: Select imported brand-name burners that match Weifu boiler products to ensure boiler thermal efficiency and meet energy-saving and low-nitrogen requirements.
Front and rear smoke boxes: The front and rear smoke boxes can be moved for easy maintenance and repair. The outer door panels of the smoke boxes are insulated with air to reduce the touch temperature of the panels.
Wet back combustion chamber: 100% water-wrapped fire structure design to improve boiler efficiency.
Corrugated furnace: Increase the heating area and have good thermal elasticity to alleviate the damage to the combustion chamber caused by thermal expansion and contraction; the large-volume furnace is conducive to full combustion, fuel saving, and achieving low-nitrogen goals.
Threaded smoke pipe: Enhance heat exchange efficiency and improve boiler efficiency.

Threaded smoke pipe: Enhance heat exchange efficiency and improve boiler efficiency.
Control system: After the boiler is started, it runs automatically, and the combustion, water level, temperature, steam pressure, etc. are automatically adjusted according to the settings to achieve automatic and safe operation of the boiler.
Energy saver: It adopts an integrated fin tube structure to fully absorb the sensible heat in the flue gas, effectively reduce the flue gas temperature and improve the thermal efficiency of the boiler.
Insulation structure: 100mm double-layer high bulk density insulation structure is adopted to reduce the external touch temperature of the boiler to room temperature, which not only increases safety but also greatly improves the thermal efficiency of the boiler.
9. Condenser: Corrosion-resistant ND steel finned tubes are adopted to fully recover the latent heat of vaporization released during the condensation of water vapor, further reduce the smoke temperature and improve the thermal efficiency of the boiler.
