hotel and school heating hot water boiler, ZOZEN thermal oil heaters become the common choice of many chemical enterprises

hotel and school heating hot water boiler, In the comprehensive office building of ZOZEN Boiler, Design Department, Technology Department, Production Department, Quality Inspection Department and Marketing Department coordinate with each other to promote the projects in a smooth and quick way. In the modern multifunctional meeting room, there is a lot of domestic and international certification acquired by ZOZEN including the A-grade boiler and BRⅡ-grade pressure container manufacturing licence, ASME “S” (utility boiler), “U” (pressure container) steel seal licence of USA and ISO9001 international quality system certification.

In March of 2019, ZOZEN Boiler successfully passed the French BV certification and became an enterprise with an in-depth factory inspection on the Alibaba international station. Through the cooperation with French BV certification, Alibaba can comprehensively studied and judged the company’s product capability, quality control capability, R&D capability and trade capability. It shows that ZOZEN Boiler has a strong comprehensive strength and all indicators fully meet the certification standards for boiler exports, hotel and school heating hot water boiler.

The base of ZOZEN DZL series coal-fired steam boiler adopts separate air chambers to keep the fuel on the grate in a good combustion state. The air dampers further ensure the sufficient combustion of the fuel and improve the fuel utilization. In addition, through advanced electrical control, it can realize the stepless speed regulation of the grate, as well as limit parameters alarm and interlock protection function to ensure the safe operation of the entire boiler system.

ZOZEN boilers adopt the ultra-low nitrogen burner with flue gas recirculation method to realize low NOx emission. Adding flue gas to the combustion air to reduce the oxygen content in the combustion air and lower the flame temperature at the combustion center, so as to greatly reduce the generation of NOx. At the same time, superimposed use of world advanced technologies such as staged combustion of ultra-low nitrogen burner and internal flue gas circulation realizes the stable and low emission of NOx.

After the raw materials are transported to the workshop, steel plates will be precisely cut by the plasma cutting machine according to design drawings. The cut steel plates after finishing three processes of rust removing, edge milling and chamfering will be rolled into workpieces for making drums by this advanced four-axis rolling machine. ZOZEN’s CNC rolling machine can complete the rolling of a drum shell within 90 seconds with a largest thickness of 100mm, an out-of-roundness and angular deviation within 1mm. Its advantages include the predeformation and cylindrical rolling of two plate ends via one-time load, arc work, shaping and leveling work on the sheet metal. It has the effects of direct pre-bending, saving time and materials to ensure the smooth progress of next welding process and further ensure the welding quality.

The industrial boiler plays an important role in the development of the beverage industry. The boiler equipment is directly related to the output and quality of beverages. As a well-known industrial boiler manufacturer, ZOZEN has provided boilers for many beverage industry giants such as Coca-Cola, Want Want, Nongfu Spring, Wahaha, Jianlibao, etc.

Industrial boiler belongs to special equipment and has high requirements for product safety factors. As the domestic well-known boiler supplier, ZOZEN has advanced mechanical equipment, mature manufacturing process and guarantee of boiler quality. In addition, via the innovation and development of ZOZEN’s professional design team, the structure and material of boiler proper are continuously improved and optimized to greatly extend boiler’s service life. It is also worth mentioning that ZOZEN’s automatic boiler control system with dozen kinds of safety protection interlocks can fully ensure boiler’s safety. In the aspect of environmental protection performance, ZOZEN boilers are also outstanding. The flue gas emission of ZOZEN boilers nearly meets the EU standards. The NOx emission is low to 30mg, which realizes the goal of low-nitrogen emission, hotel and school heating hot water boiler.
