A set of industrial boiler with sufficient output and stable heating supply can directly affect the daily production of a food company. ZOZEN DZL series biomass-fired steam boiler adopts the single-drum longitudinal layout and chain grate stratified combustion method. ZOZEN technicians has optimized the design of the feed hopper, grate width and length, speed of grate reducer and position of secondary air outlet by analyzing the different fuel characteristics and practical use requirements of customers to ensure the sufficient combustion of biomass pellets and improve the combustion efficiency. Meanwhile, DZL series biomass fired steam boiler adopts the thread smoke tubes developed by ZOZEN to strengthen the heat transfer and improve the thermal efficiency. The heat transfer coefficient of thread smoke tube is 1.8 times higher than that of ordinary smoke tube and the thermal efficiency of boiler is over 88%, which can fully meet the daily production demands of enterprises.
Thermal oil heaters, also known as organic heat carrier boilers, adopt the organic heat carrier as heat medium to realize heat transfer. Due to the high temperature characteristics of organic heat carrier, thermal oil heaters can realize low-pressure and high-temperature heating with an oil output temperature of 350℃. Thermal oil heaters adopt injection-type forced circulation system and heat exchange surface adopts round and square coil structures, which also have a wide fuel adaptability of oil, gas, coal, biomass. ZOZEN Boiler, as a leader in the boiler industry, has improved and upgraded its YQW series, YQL series and YLW series thermal oil heaters applied in the chemical industry to meet the production demands of chemical enterprises. They are equipped with complete operation control and safety monitoring devices which can precisely control the working temperature to ensure boiler's safe operation. They are popular among and favored by chemical enterprises.
ZOZEN WNS series gas-fired hot water boiler adopts packaged structure, which is convenient and quick for installation to save a lot of basic construction costs for the enterprise. Its internal structure adopts large-diameter waveform strove furnace which can effectively absorb heat expansion to add the radiation heating surface and ensue the low emission of NOx with the advanced low-nitrogen burner to improve the fuel utilization. What's more, its thread smoke tubes have scientific pitch and depth to further strengthen the convective heat transfer and make boiler's thermal efficiency reach 95% and above.
ZOZEN Boiler has guided the industrial boiler manufacturing quality for decades. It also has established the technology standards of blanking digitization, automation of welding and assembly moulding to realize the specialized and scale production of boiler's main parts. For further improving the boiler production efficiency and product quality, ZOZEN's Yixing factory introduced a series of new equipment including laser cutting machine, grooving machine, blending machine and sand blasting machine.
Interested customers from Hubei province visit ZOZEN Boiler factory for field investigation and deputy general manager introduces the company profile of ZOZEN Boiler and advantages of SZS series gas-fired boiler. Its boiler proper adopts D-model structure. One side is furnace and the other side is convection heating surface. It also adopts membrane wall structure, foreign advanced burner, economizer and condenser at the end of flue gas duct, which can lower the exhaust gas temperature to 60 ℃, enhance the thermal efficiency to 98% and above, and reduce the emission of NOx to less than 30mg/Nm3. This equipment is featured by energy-saving, eco-friendly, safe, highly-efficient and easy to operate and maintain. Its automatic control system can also realize unattended operation.
Recently, ZOZEN delivered the thermal oil heaters for Hengfa Energy Saving Technology. As a leading industrial boiler manufacturer, the thermal oil heaters of ZOZEN have wide adaptability of fuels, are suit for natural gas, coal gas, marsh gas, diesel, light oil, etc. The heat exchange surface adopts three-pass round coil tube structure, which features more sufficient heating surface. The heaters are also equipped with the advanced burners to ensure the NOx emission is below 30mg/m3.
In recent years, with the continuous development of "the Belt and Road", China's manufacturing industry has gradually occupied the economic market of Sri Lanka. Sri Lanka Kaka's delegation had conducted a conprehensive investigation of industrial boiler manufacturers in China to choose a good supplier. Through the collection and analysis of the boiler market data in China, ZOZEN stood out with prominent quality in industrial boilers. After preliminary communication, the delegation was attracted by ZOZEN's professionalism and decided to conduct a fied inspection.
Recently, the expert group from National Industrial Boiler Quality Supervision and Inspection Center visited ZOZEN, and the two sides conducted in-depth exchanges on issues such as the future development trend of the industrial boiler industry. Led by Mr. Zhang Guoping, General Manager of ZOZEN, they visited the modern production base of ZOZEN.
