5000 6000kg h dual fuel gas oil fired boiler 4tph, With advanced combustion and condensing technology, the thermal efficiency of ZOZEN gas boilers is over 98%

In March 2019, Wuxi Zozen Boilers Co., Ltd. successfully passed the French BV certification and became an in-depth factory inspection company of Alibaba International Station. Alibaba cooperated with the French BV certification and comprehensively judged companies' product capabilities, quality control, research and development capabilities, and trade capabilities, which further proved that ZOZEN's comprehensive strength is strong, and all indicators fully meet the boiler export certification standards, 5000 6000kg h dual fuel gas oil fired boiler 4tph.
The SZS series gas-fired steam boiler produced by ZOZEN Boiler adopts the D-type and full membrane wall structure. The large furnace space ensures the sufficient combustion of the fuel and has good gas tightness. Meanwhile, the furnace body is made of high-quality aluminum silicate fiber and refractory mud for insulation to control the furnace body temperature below 45℃ and control the heat loss; with the additional energy-saving device at the end of the flue gas duct, the boiler thermal efficiency can be improved to more than 98%, 5000 6000kg h dual fuel gas oil fired boiler 4tph.
The structural design focuses more on details. The sealing of both sides of membrane wall and drums adopt comb plate. The boiler features a drainage system of condensation water in convection zone to prevent the corrosion of furnace body by acid condensate. Advantages: reduce the frequent maintenance of furnace and extend the boiler working life, 5000 6000kg h dual fuel gas oil fired boiler 4tph.
In terms of welding technology, ZOZEN longitudinal and circumferential seam welding adopts advanced automatic submerged arc welding technology, and 100% X-ray detection is carried out on the welding seam to ensure the welding quality. The welding of the smoke tube and tube sheet adopts pre-expansion first to eliminate the gap between the tube and tube sheet, and then adopts the automatic argon arc welding technology, which can effectively eliminate the stress and extend the service life of the boiler.
In the rubber industry, steam boilers are widely used in the processes of rubber calendering, vulcanizing and drying. PT.Industri Karet Deli is a large rubber enterprise in Indonesia, it planned to upgrade production equipment to improve their core competence. The company contacted ZOZEN and signed the purchase contract of SZL 20 tph SZL series coal-fired boiler. This series of water tube boilers adopts unique grate bars and appropriate air registers to ensure the stable running of boilers and improve the thermal efficiency.
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.

In industries such as chemicals, plastic packaging, new materials, and building materials, thermal energy supply is closely related not only to production continuity, but also to product quality and operating costs. As companies place higher requirements on process temperature control, fuel adaptability, and system stability, thermal oil boilers are becoming an important heat source in many industrial applications. Based on different fuel conditions and production needs, ZOZEN Boiler continues t...02 Jun 2026 -
Packaging connects production with consumption. A carton, a piece of corrugated board, or a roll of plastic film may look light and simple, but behind each of them is a stable, continuous, and process-matched thermal energy system. As demand continues to grow in food packaging, industrial packaging, e-commerce packaging, and plastic packaging, the packaging industry is placing more specific requirements on boiler equipment: stable steam supply, fuel adaptability, process temperature control, ope...26 May 2026 -
When an industrial boiler arrives on site, what first catches a customer’s attention is often not the specification sheet, but the overall appearance of the equipment in the plant environment. For boiler equipment, exterior design is not only about visual presentation; it also reflects the manufacturer’s approach to product details, on-site management, and brand image. ZOZEN Boiler has upgraded the exterior of its SZL series biomass boiler, presenting a more unified visual design and...19 May 2026
