0.7mw boiler, new generation of ZOZEN biomass-fired boiler easily meets the standard

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.

China Academy of Space Technology is China's main space technology and product development base. Recently, the overall boiler system solution customized for the base by ZOZEN was highly efficient and environmentally friendly, which was more than 5% higher than the average measured thermal efficiency of conventional boiler systems in the industry. Therefore, ZOZEN won unanimous praise from the review experts, and finally realized the first cooperation with the China Academy of Space Technology.

The SZS series oil-fired/gas-fired boiler proper adopts the D-type structure. One side is the furnace, and the other side is the convection heating surface. The partition walls around the furnace body, the partition wall between furnace and convection section, and the front and rear walls all adopt the membrane wall structure. There are foreign advanced burner, economizer and condenser installed at the end of flue gas duct, which can lower the exhaust gas temperature to 60℃, achieve the thermal efficiency of over 98% and control the emission of NOx to less than 30mg/Nm3. This kind of boiler has the characteristics of energy saving and environmental protection, safety and efficiency, simple operation and maintenance, and fully automatic control system which can realize unattended operation.

0.7mw boiler, Rashid Paper Mills Ltd., established in September of 2016, is a paper manufacturer of the well-known Rashid Group in Bangladesh. It mainly produces various types of paper used for writing, printing and offset printing. It currently has two independent production lines with a daily production capacity of 200 tons of paper. It also exports high-quality paper to overseas market. In order to ensure the heat source supply of paper production lines, Rashid Paper Mills Ltd. chose to introduce the advanced ZZ series medium-temperature and medium-pressure boiler from China with a rated pressure as high as 3.82 Mpa and sufficient high-temperature steam supply.

Wuxi ZOZEN Boilers Co., Ltd. feels proud of being a leader and innovator of industrial boiler. For over 30 years, ZOZEN has accumulated rich project experience in designing and manufacturing highly-efficient thermal oil heaters by cooperating with customers from various industries. The thermal efficiency of ZOZEN’s gas-fired thermal oil heaters can reach above 95% and that of ZOZEN’s coal-fired thermal oil heaters can reach above 85%, which is 5% higher than the average thermal efficiency of normal boiler system in the industry. ZOZEN provides one-stop boiler system purchasing service and customizes the waste heat recovery system for customers to meet the heat source demands of various plants, 0.7mw boiler.

The longitudinal and circumferential seam welding of ZOZEN adopts advanced submerged arc automatic welding technology to ensure the welding quality. All longitudinal and circumferential seams are subjected to 100% radiographic inspection.

When the development of ZOZEN Boiler is transformed from extensive type to fine type, it steps on the road of green manufacturing. ZOZEN puts the concept of green products to equipment to ensure the healthy development of the whole industrial chain by strictly adhering to environmental management system and energy management system. With 120,000 square meters of modern production base as the core competitiveness, ZOZEN fully implements 6S management and informatization management via management methods such as visual management, sample area and regular examination to promote lean production, set reasonable layout of enterprise workshop and advanced processing equipment, simplify the processing steps and save raw materials to ensure the green manufacturing in every link of the production process.
