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.
Affected by the global COVID-19 conditions, many enterprises change their offline business to online business. To solve the problem of communicating with overseas customers, ZOZEN Boiler has purchased a complete set of video conference equipment to keep a smooth communication with overseas customers. Recently, ZOZEN Boiler has organized a video conference with a Korean customer about the circulating fluidized bed boiler project. ZOZEN's general manager Zhang, sales vice general manger Liu, boiler designer Yang and domestic sales manager Wang attended the conference.
ZOZEN YQW series horizontal thermal oil heater adopts multi-loop coil structure with good safety performance and sufficient heating surface. Meanwhile, ZOZEN Boiler can also design the waste heat recovery system for users to ensure that boiler's thermal efficiency can reach 95% and above. What's more, automatic control system also ensures the safe and stable operation of thermal oil heater to realize the sustainable high-temperature and low-pressure heating supply. In addition, ZOZEN’s gas-fired thermal oil heater is equipped with advanced low-nitrogen burner to ensure that boiler's NOx emission is lower than 30mg/Nm3 to achieve the excellent performance in environmental protection.
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 guides and cultivates different kinds of talents according to their different characteristics and laws of growth. In late July, ZOZEN Boiler launched a three-day job training program for new graduates, which was held by the vice general manager and boiler designer, Zhu Qiuping. As a senior boiler engineer, vice general manager Zhu has more than 30 years of experience in boiler design, especially in designing large-scale circulating fluidized bed boiler and gas-fired boiler. He is now the head in charge of ZOZEN Boiler's R&D and design department and is one of the representative persons of ZOZEN Boiler's "soft power".
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.
Shandong Luhua Group Co., Ltd. is a national key leading enterprise of agricultural industrialization in China with 24 production bases and covers industries of edible oil, condiments, vegetable processing and so on. Its annual production capacity of edible oil is 1 million tons and that of condiments is 100,000 tons. ZOZEN's SZS series gas-fired steam boiler and SZS series low NOx gas-fired saturated steam boiler have sufficient heating surface and enough steam and water space to ensure the stability of boiler indexes. Meanwhile, full membrane wall structure can ensure excellent airtightness and thermal efficiency (above 98%). ZOZEN Boiler also adopts ultra low NOx burner via flue gas circulating can ensure the complete combustion of fuel and control the emission of NOx at the same time. It is estimated that boiler's NOx emission is less than 28mg/m3, which completely meets the standards of Environmental Protection Department of Shandong Province.
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.
