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.
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.
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.
A set of industrial boiler with sufficient output and stable heating supply can directly affect the daily production of a food company. ZOZEN DZL series biomass-fired steam boiler adopts the single-drum longitudinal layout and chain grate stratified combustion method. ZOZEN technicians has optimized the design of the feed hopper, grate width and length, speed of grate reducer and position of secondary air outlet by analyzing the different fuel characteristics and practical use requirements of customers to ensure the sufficient combustion of biomass pellets and improve the combustion efficiency. Meanwhile, DZL series biomass fired steam boiler adopts the thread smoke tubes developed by ZOZEN to strengthen the heat transfer and improve the thermal efficiency. The heat transfer coefficient of thread smoke tube is 1.8 times higher than that of ordinary smoke tube and the thermal efficiency of boiler is over 88%, which can fully meet the daily production demands of enterprises.
Founded in 2002, Wujiang XinYi Textile Co., Ltd. is a joint-stock private enterprise integrating production and trade of various kinds of high-end fabrics. With the expansion of business, XinYi Textile introduced the ZOZEN biomass-fired boiler. This series of steam boiler is a horizontal chain grate boiler. It has excellent safety performance. The extremely low water level electrode can effectively prevent boiler water shortage accidents caused by extremely low water level operation in manual mode and strengthen the safety protection of water level control.
