The Dongwha Finland plant is located in southern Finland. The plant has been owned by Dongwha Enterprises since 2017, mainly produces wide range of different types of impregnated papers. ZOZEN Boiler provided a set of 7 million kcal thermal oil heater to Dongwha Finland under the strict circumstance of COVID-19 pandemic.
ZOZEN Boiler recently provided boilers for several industries, for instance. the construction material factory, the heat supply industry, the chemical industry and the textile industry, etc.
The 3 sets of 29 MW gas-fired hot water boilers serving for Jin-an Thermal Power in Tianjin were installed in 2015. The boiler is a common type for central heating which adopts the full membrane wall structure and a D-type layout. It has the characteristics of micro-positive pressure combustion, no air leakage, low heat loss caused by exhaust gas and high thermal efficiency. During the boiler manufacturing process, ZOZEN Boiler emphasizes that the welding of each baffle must be tight, and the height of welding leg should meet the requirements specified on the design drawing to ensure the leakproofness of the boiler. In addition, ZOZEN Boiler also sets strict welding standards for detailed parts including the door opening and kiln eye to prevent the high-temperature flue gas from leaking.
This is our ZOZEN brand new WNS steam boiler. It has three basic security precautions. The first, it's a water level gauge. The second, it's a pressure gauge. The third, it's a safety valve. In addition to the three basic security precautions, our ZOZEN uniquely design an extremely low water level protection. These security precautions greatly ensure the safe operation of the boiler.
Continuing the 2020 industrial live streaming mode, ZOZEN Boiler has made the online visit normal. Recently, at the modern production base of Wuxi ZOZEN Boiler, technicians had connected with Finnish customers via the live streaming to show the whole process of the boiler hydrostatic test. Through the live streaming, ZOZEN not only showed the entire panorama of the hydrostatic test, but also showed the operating steps and pressure gauge values on the top of the boiler. The customers were very satisfied.
ZOZEN WNS series oil-fired/gas-fired boiler is a kind of fire tube wetback boiler with a two-pass or three-pass structure. It is equipped with foreign advanced burner, economizer and condenser installed at the end of flue gas duct to lower the exhaust temperature to 60℃, achieve the thermal efficiency of over 98% and control the emission of NOx to less than 30mg/Nm3. It has the characteristics of compact structure, small covering area, short installation period, easy operation and complete automatic control system which can realize unattended operation.
ZOZEN 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.
This is gas-fired/oil-fired thermal oil heater from ZOZEN Boiler which is widely used in petroleum, chemical fiber, pharmaceutical, printing and dyeing and other industries that require high-temperature heating. The thermal oil heater adopts heat medium oil to transfer the heat energy. Applying high temperature of heat medium oil, the boiler can realize low pressure and high temperature heating with a working temperature of 320℃. Meanwhile, our thermal oil heater is equipped with the complete device for operation control and safety supervision which can precisely control the working temperature with convenient operation and high safety performance.
