Boiler economizer is an energy-saving device installed at the end of boiler flue, which can absorb the heat of high-temperature flue gas, effectively reduce the smoke exhaust loss, improve boiler thermal efficiency and reduce the fuel consumption.
Wuxi ZOZEN Boilers Co., Ltd. is a well-known industrial boiler manufacturer in China. With the excellent product quality and comprehensive sales network, ZOZEN boilers have been sold to many countries and regions around the world. The video shows the waste heat recovery equipment matching with ZOZEN thermal oil heater, which is the energy-saving equipment selected based on the customer’s actual working conditions. The waste heat recovery equipment can make full use of the flue gas waste heat to effectively improve the thermal efficiency of the thermal oil heater.
WNS series gas-fired steam boilers customized by ZOZEN Boiler have the advantages of high thermal efficiency, strong environmental protection performance and automatic operation. It is commendable that the WNS series gas-fired boilers adopt the patented appearance of ZOZEN Boiler (patent No. ZL202030031426), which has beautiful appearance and good corrosion resistance.
As a professional industrial boiler manufacturer, ZOZEN Boiler has always maintained the advanced technology and equipment. It owns 600 sets of advanced production equipment in the industry, with high processing precision and high efficiency, guaranteed boiler quality, and realized large-scale production with short delivery period.
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.
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 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.
The YQW series of boiler can realize fully automatic operation, including automatic combustion, automatic adjustment of the liquid level of the expansion tank, outlet temperature, flow rate and automatic protection. Meanwhile, the PLC control system is easy to operate. Various kinds of settings can be completed through the intelligent man-machine interface.
