Entering the modern production base of ZOZEN Boiler, we can see the orderly work of various standardized posts such as blanking workshop, assembly workshop and painting workshop at any time, showing the clean and tidy appearance of large-scale industrial boiler enterprises. Here, we can feel the strong cohesion and unity of the frontline workers in ZOZEN Boiler.
In order to meet the demands of the project to construct a comprehensive PVC resin production plant with an annual output of 60,000 tons in Mekele, Ethiopia, China CEC Engineering Corporation purchased 3 sets of SZL series coal-fired chain grate water tube steam boiler from ZOZEN Boiler who had completed the shipment recently. ZOZEN SZL series coal-fired steam boiler has the sufficient output, a high degree of automation and a high thermal efficiency of over 82%. In order to improve the fuel utilization, there are multiple separate air chambers and air dampers installed at the lower part of the grate to achieve the precise air distribution to meet the demands of air volume needed by fuel in each combustion stage. ZOZEN Boiler also customized the dust removal, desulfurization and denitration equipment at the end of the boiler to ensure that the exhaust gas emission of the boiler could meet the local environmental protection standards.
Vietnam has abundant coal resources, including anthracite, bituminous coal, lignite, and peat. Vietnam anthracite has the characteristics of high calorific value, low ash, low nitrogen, low phosphorus and low sulfur. ZOZEN SZL series coal-fired boiler has wide fuel adaptability and sufficient fuel combustion, and has established an excellent reputation in the Vietnamese market.
Shenyang Third Thermal Heating Co., Ltd. is one of the largest companies of the central heating industry in Shenyang. 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.
