Boiler economizer is an energy-saving device installed at the tail of boiler flue. Its working principle is to heat boiler feed water into saturated water under drum pressure by absorbing waste heat in flue gas. As the economizer absorbs the heat of high temperature flue gas, it further reduces the exhaust temperature of flue gas, thus reducing the exhaust loss, improving the thermal efficiency of the boiler and effectively reducing the fuel consumption of the boiler. It is one of the important equipment of boiler system.
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.
The production of an industrial boiler with good quality will go through several links, such as blanking, welding, assembly and inspection. ZOZEN Boiler has a set of comprehensive production system and quality control system to assure product quality in the manufacturing process.
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.
Recently, the spot supply of ZOZEN gas-fired boiler solved the urgent problem of the unstable steam supply of biomass gasification boiler during the upgrading and reconstruction of the central heating project. ZOZEN SZS series gas-fired boiler of this tonnage is mainly composed of boiler body, connecting smoke tube, burner, steam-water system, instrument, economizer and condenser. The boiler system has the characteristics of high thermal efficiency, sufficient output, green combustion, pollution-free emission and fully automatic operation.
The new customized type of ZOZEN SZS series oil/gas-fired boiler is now available on the website. The new appearance of SZS series acquires the patent No. CN202030030831.X with the good performance of anticorrosion. Also, the well-structured 'D' type chamber with large volume design ensures the sufficient combustion and good airtightness. The imported low-NOx burner can easily control the generation of the NOx.
With its after-sales service system integrating maintenance service, information feedback, spare parts supply and technical training, ZOZEN Boiler has truly responds in time and solved problems quickly.
According to the new staff training system of ZOZEN Boiler, the new round of the boiler room site training has begun. Guided by Mr. Lu Xing, the sales manager of ZOZEN Boiler, the new staffs of ZOZEN Boiler went to the boiler room of one customer, to visit and learn how the boiler operating in the actual situation. The purpose of boiler room visit is to strengthen the knowledge and to better understand the relevant work contents.
