The dust removal door is also called the soot door, it is set up for the biomass-fired and coal-fired boiler for cleaning the dust and ash. The operator can check the ash accumulation status of the boiler and clean the ash and coke. Commonly, the dust removal door of the packaged boiler will be installed before delivery.
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.
The shipment of ZOZEN SZS series of boiler. This series of steam boiler adopts a large furnace and an advanced burner to ensure the complete combustion of the fuel and improve fuel utilization. Besides, energy-saving devices are equipped at the end of the flue to improve the thermal efficiency of the boiler to more than 98%. In addition, with an intelligent control system, the boiler can realize automatic operation and automatic adjustment of steam temperature and pressure, which can realize energy saving and consumption reduction while ensuring the steam supply.
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.
The skid mounted steam boiler is to place all the equipment such as the boiler proper, economizers, burners, valve instruments, electric control cabinet, water treatment, economizer circulating pumps, feeding pumps, deaerators on one or two skids to form an integral movable boiler system. All the pipes and valves on the skid have been installed, furthermore, the connecting pipes between the skids have also been installed in the factory, which can save plenty of costs for clients. This kind of boiler is especially suitable for the food industry, the chemical industry, the textile industry, the medicine industry, the rubber industry, the building materials industry and so on.
SZS series boiler is designed with longitudinal double drums and " D " type chamber structure. Furnace is placed on the right and convection tube bank is on the left, super heater is arranged at convection tube bank. 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 water cooling tube wall. Furnace and tube bank are totally separated by the membrane water tube cooling wall at the left side of the furnace. The back part of bundle 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 fine coil economizer and condenser, and finally is discharged to atmosphere through chimney.
