6 ton commercial steam boiler, with 30-years innovation, the manfacturing level of ZOZEN boiler is industry leading

The ZOZEN WNS series oil-fired steam boiler was successfully delivered to the capital of Caracas, Venezuela in early June. After completing the installation and commissioning the boiler will provide a stable heat source for the production line of Inversiones Goa 7 C.A, further enhancing the efficiency and overall competitiveness of the enterprise.

The DZL series biomass-fired horizontal three-pass water-fire tube chain grate boiler is pre-assembled boiler with a capacity of 2-20 tph (hot water boiler: 1.4-14MW) and a thermal efficiency of over 88%. By extending the furnace arch, increasing the furnace height and adjusting the width and length of grate, ZOZEN takes the lead in solving the problems that easily occur in biomass-fired boilers such as furnace arch collapse, furnace door burnout, hopper tempering and tube wall coking. It has the characteristics of wide fuel adaptability, small covering area, convenient installation and high thermal efficiency.

In September, ZOZEN SZL series biomass-fired boiler provided for Inner Mongolia Jinshan Mining had been debugged and put into operation smoothly. The boiler has a higher furnace and reasonable grate rotate speed to ensure the sufficient fuel combustion and improve the thermal efficiency to 88% and above. At the same time, the boiler convention area is also equipped with an ash removal device independently developed by ZOZEN which not only has good tightness, but also greatly reduces the workload of the boiler operation and maintenance personnel, so as to help Jinshan Mining achieve clean production and build a green mine.

6 ton commercial steam boiler, Designed to wrap the whole furnace body for heat preservation. There are no heat transfer supports between the furnace body and the outside surface. The appearance is mirror polished stainless steel with a protective coating. After the boiler is installed, remove the coating and show the mirror polished stainless steel appearance. Advantages: a good-looking appearance, low temperature of surface, low heat dissipation.

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.

Based on low-nitrogen and energy-saving technology, ZOZEN is committed to developing widely used and advanced technology, products and services. In this way, ZOZEN provides heat source support for various industries around the world to promote future cutting-edge business and realize the application dreams of users in various fields. The low-nitrogen boilers designed by ZOZEN can control the emission of NOx to lower than 30mg, which are widely used in various industries and are attractive for the national and international market, 6 ton commercial steam boiler.
