ZOZEN Boiler as a leader enterprise in the gas-fired boiler industry always pays attention to the energy-saving and environment protective technology and has received remarkable achievements. In order to make full use of the waste heat and to meet the different requirements of different working conditions, ZOZEN engineers have innovatively designed various types of the energy-saving gas-fired boiler system solutions, such as the condensing type, air preheating type, waste heat boiler type, etc. Through the energy efficiency test, the thermal efficiency of ZOZEN energy-saving gas-fired boiler is over 98%, which is better than the national energy efficiency standard.
ZOZEN SZS series condensing gas-fired boilers are typical high-efficiency, energy-saving and environment-friendly boilers with large furnace volume, sufficient radiant heating surface, sufficient fuel combustion and high thermal efficiency of 98%. With advanced combustion equipment, the emission of nitrogen oxides can be less than 30 mg/nm3.
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.
ZOZEN WNS series oil-fired and gas-fired boiler is designed with large-diameter corrugated furnace and threaded smoke tube, which makes the heat transfer of the boiler more efficient. With the condenser and economizer installed, the thermal efficiency of the boiler can reach over 98%, which is well received by the market.
Industrial boiler is the main thermal power generation equipment in China's production and life, and its quality has an important influence on industrial development and residents' heating in winter. The fundamental factors that affect the quality of boiler are production and processing technology and tooling equipment. In the long-term production and operation, ZOZEN Boiler, as a well-known boiler brand, always pays attention to the renewal of process equipment, so as to continuously improve the quality and performance of various series of boiler products.
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 WNS series gas-fired steam boiler adopts the large-diameter corrugated furnace and threaded smoke tube to increase the heating surface, reduce the thermal stress and improve the boiler's safety performance; meanwhile, in order to reduce the heat loss caused by gas exhaust and operating costs, ZOZEN also adds energy-saving devices at the end of the flue gas duct to improve the thermal efficiency to over 98%. In addition, the two sets of boilers also meet the ASME standards, which proves that ZOZEN product quality is up to international standards.
The YQW series gas/oil-fired thermal oil heater adopts the three-pass round coil whose end adopts the necking coil, which effectively protects the furnace wall at the boiler end. It is equipped with the advanced combustion device and fully automatic operating device. The boiler adopts the packaged structure for delivery, and it can be put into operation only by connecting gas (oil) and electricity after being placed on the project site. With excellent performance and quality, ZOZEN YQW series gas-fired thermal oil heater has won the favor of Jiangsu Guanghui Packaging Materials Co., Ltd.
