In order to improve the thermal efficiency of industrial boiler system, ZOZEN Boiler, a professional boiler manufacturer, will select air preheater, energy-saving condenser and other devices according to the actual situation of customers when designing the boiler system to recover high-temperature flue gas and reduce the heat loss of flue gas.
Welding is an important working procedure in boiler production, which is generally divided into automatic welding, semi-automatic welding and manual welding. In the production base of ZOZEN Boiler, a professional boiler manufacturer, front-line welders are ensuring the quality of boiler welds with superb technical level, lofty ideological awareness and strong sense of responsibility.
The boiler is additionally provided with an air preheater at the end of the flue gas, and the air is preheated to a certain temperature with the heat carried by the flue gas of the boiler. The heated air enters the combustion room again, which not only accelerates the drying, ignition and combustion processes of the fuel, ensures the stable combustion in the boiler, but also improves the average temperature level in the boiler, thereby strengthening the radiation heat transfer in the boiler and effectively improving the thermal efficiency of the boiler.
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.
