The New Boneng electric boiler technology characteristics

The New Boneng electric boiler technology characteristics

Suzhou New Boneng Electric Boiler CO.,LTD is located in Suzhou National High-tech Development Zone students Pioneering Park, is a professional research and manufacture of electric hot water boiler, electric steam boilers, electric storage water heaters, heating system, hot oil furnace conductance of the high-tech enterprises, products have a clean, efficient, environmental protection, green features. Such devices are widely used in air conditioning heat source system of hospitals, schools, hotels, office buildings, apartments and industrial and mining enterprises, industrial production and sanitary hot water. Company to introduce the United States, Europe 's most advanced manufacturing technology, electrical components and control system, and in strict accordance with the ISO9001quality assurance system implementation, operation, product quality and international synchronized.

Products strictly according to the’’National Boiler and Pressure Vessel Safety Supervision regulations’’

☆ National" steam boiler safety technology supervision regulations."

☆ National’’hot water boiler safety technology supervision regulations’’

☆ UL (Underwriter Laboratories Inc.) standards
The hot water boiler to follow UL834 ,The steam boiler to follow the UL1453

☆ ASME (American Society of Mechanical Engineers) standards
And product quality certification for the ISO9001-2000 (SGS)
One, pressure vessel

Assembly of the boiler furnace in line with the GB16508-1996 standard, pressure vessels for enamel treatment, effectively improve the container corrosion resistance especially anti oxidation ability. Steam boiler steam outlet is provided with a steam separator, to provide high quality steam.

  New Boneng Electric Boiler with the world's most advanced glass enamel process, extra-thick low carbon steel plate surface temperature of 900 ℃, the base glaze, surface glaze process, deposited into a glass enamel coating, its enamel protective coating and steel plate closecombination will completely cover the plate surface. To eliminate harmful substances on the corrosion of the steel plate, with insulation, heat insulation performance. The enamel coating and the steel plate to maintain the thermal coefficients, thereby not leaving because of changes in the thermal expansion and contraction of the enamel coating of brittle fracture or fall off. From the direction of long-term development of the electric boiler, their life and security of the most valued customers, The quality of the electric boiler and a key component of its life is the material of the liner. Enamel interior, the special anti-corrosion insulation and withstand voltage characteristics ,so that greatly extend the life of the electric boiler in the world this technology has many electric boiler manufacturers, the container has a long life of more than 20 years.

The advantages of using enamel processing

Corrosion resistance: 900 ℃ high temperature processing of the base enamel surface glaze, ensure that the enamel of the clouds integrity and uniformity, thus completely isolated from water corrosion
Adhesion: After high-temperature sintering, and strengthen the enamel powder and thicker steel plate one melt to form a strong bonding force between the molecules, the stress distribution, super sturdy impact-resistant, high temperature
Durability: the characteristics of resistance to rust, corrosion, scale, longer life expectancy
Stability: has the ductility, thermal expansion and contraction due to temperature changes liner, the enamel function does not produce any problems

Two, the electric heating tube

The core component of the electric boiler electric heating tube, and its main requirements are: reliable, automatic cleaning, do not burn, long life.

1.     guarantees electric tube service life:

①    nichrome alloy components
The INCO800 nichrome heat resistance up to 816 ° C, even if the scaling is not easy to burn out, high mechanical strength, corrosion resistance, chemical stability, is suitable for various water electric boiler.

②   The optimal power density design

The basic parameters of the heating tube is the power density, it is per square inch electric wall heat transfer of power. Power density is too low, bring oversize electric tube furnace and boiler room covers an area of ​​increased heating tube expansion is small, not easy to automatic cleaning affect the life span; high watt density, high temperature resistance wire tube also affect life expectancy. I am using the heating tube optimal power density design, both to ensure the life of the heating tube to ensure that its cleaning function. Its life expectancy is much higher than a similar level of the heating tube.
③ electrode structure
Nickel-chromium resistance wire welding on large diameter electric extreme, through the power of extreme and power connections, power extreme ensure that the beginning part of the electric tube flange plate 80mm long heating part, so that the junction temperature of the nickel-chromium wire low, to prevent the joints burn.

④ The U type tube design
Electric heating tube diameter 8mm, structure for U type tube design, smooth tube wall, between pipe and pipe have spacious space, not easy scaling, not easy to accumulation of impurities, the steam boiler, the pipe wall is not easy to accumulate" steam bag", which led to the joint burn.

U type tube structure permits free expansion, using optimal power density, U type tube has sufficient volume to scale expansion, not the result of scaling and burned-out electric heating tube.

⑤ high purity and high density magnesium oxide filler
The concentric configuration of the nickel-chromium resistance wire in the heating tube, between the resistance wire and the tube filled with high purity magnesium oxide powder insulation and heat transfer effects. The packing density of magnesium oxide on heating pipe work reliability is critical. High-density padding to ensure good insulation, heat evenly.

2, stainless steel flange connection
The stainless steel S304 sealing flange connection. Nichrome element allows a higher operating temperature of the heating tube, and thus the work is compact, the diameter of only 8mm, the flange size is only 2-1/2 "x 2-1/2", this will enable compact furnace, boiler room station area and small series of advantages. Replacement of electric tube flange size is small, the drum does not turn on the water situation, replacement of water.
