dual boiler, ZOZEN boiler organizes employees to visit the gas-fired steam boiler room

dual boiler, As an industrial boiler manufacturing company with more than 30 years of development history, ZOZEN today's achievements are inseparable from its sustainable development concept.  Recently, ZOZEN reached cooperation with Libbey Inc., the global glassware industry giant. The two sides shared the same development concepts and became friendly and trustworthy partners.

In June of 2020, according to the development strategy of overseas market, ZOZEN Boiler made a in-depth communication and negotiation with ESCOM in Mexico and two sides reached an agreement on the cooperation details. After ESCOM officially became ZOZEN’s dealer in Mexico, ZOZEN provided professional technical training for ESCOM to ensure ESCOM can provide professional and high-quality service for local customers, dual boiler.

The former part of ZOZEN SZL coal fired boiler body is surrounded by membrane wall, its upper part connects with boiler drum and lower part connects with header, which forms a combustion chamber to absorb the radiated heat from furnace there are dense convection tube bundles between the back side of upper and lower drum, the high temperature smoke enters a separate economizer after flushing heat absorbing surface then discharge from chimney.

PT.Mikie Oleo Nabati is an palm oil company in Indonesia. Steam boilers are used for refining, bleaching, deacidification, deodorization, fractionation and other processes in the palm oil production. The biomass-fired boilers the company ordered from ZOZEN can perfectly resolve the problems of scaling, abrasion, burning front arch and feeding hopper. The thermal efficiency of ZOZEN’s biomass-fired boilers can reach above 88%.

ZOZEN’s biomass-fired chain grate boilers have significant advantages such as wide fuel adaptability, low original emission concentration, low operating costs and simple operation. Based on the development of environmental protection, ZOZEN Boiler has been designing and manufacturing chain grate boilers very early. At present, the company’s biomass-fired chain grate boilers have formed a series of industrial boilers including DZL, SZL, DHL, SHL, etc. They can ensure fuel’s sufficient combustion when burning shaped biomass fuel pellets or directly burning biomass bulk materials. The biomass-fired boilers designed by ZOZEN adopt advanced arch design, original membrane wall structure, special slag removal technology and reasonable grate sealing structure with outstanding performance advantages.

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.

Be it a firetube, watertube, hot water, or steam boiler, they are all effective and efficient in their own unique ways. To learn in more detail about the differences between boiler types, visit the section on ZOZEN website.
