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.
The kick-off meeting of the Lean Factory-Standardization Project of ZOZEN was successfully held at 9 a.m. on April 20, which marked the beginning of ZOZEN's comprehensive reform. From the moment on, ZOZEN would deeply implement the concept of Operation standardization and Process standardization and comprehensively improve the internal management level and overall competitiveness. General Manager Mr. Zhang Guoping, mid and senior-level managers attended the meeting.
The packing groups of ZOZEN during the outbreak of coronavirus. Workers wear masks every day while doing packing work. The production work is proceeding orderly.
The delivery is proceeding orderly during the outbreak of coronavious. Although the outbreak of coronavirus has caused a certain influence on the personnel flow, logistics and transportation. The shipping department has also returned to the busy state with the recovery of logistics.
SZS series boiler is designed with longitudinal double drums and " D " type chamber structure. The furnace is on the right and convection tube bank is on the left. The body is fixed on the basement by middle and both end flexible supports and make the boiler expand horizontally sideways. Around the furnace is membrane wall. Furnace and tube bundle are totally separated by the membrane wall at the left side of the furnace. The back part of convection tube bank is sparse shift structure, front part is aligned structure. Smoke from furnace outlet enters re-burning chamber, convection tube bank area, and then from left front part enters spiral fin coil economizer and condenser, and finally is discharged to atmosphere through chimney.
The body and the middle partition wall of ZOZEN DHL series corner tube hot water boiler adopt membrane water wall complete sealing structure, which greatly reduces the boiler heat loss and improves the boiler thermal efficiency. Meanwhile, the flag heating surface of this series of boilers is designed with patented technology of the same smoke velocity in variable cross-section, so that the flow velocity of the smoke in heated surface between the high temperature zone and the low temperature zone is uniform, reducing the ash accumulation and increasing the heat transfer co-efficiency. In addition, the water circulation structure of DHL series coal-fired boilers is identified the first domestic product in China due to its reliability and advancement. It is widely used because its comprehensive performance has exceeded similar products on the market.
