The new generation of SZL series boiler is cooperated with Shanghai Jiaotong University. It increases the furnace height, increases rotating speed, adds ash blowing device and designs ash removal system at the bottom of the grate. These well solve problems like scaling, abrasion, front arch, etc. It can also reduce the maintenance and operating costs and extend the service life of the biomass-fired boilers.
ZOZEN WNS series gas/oil-fired steam boilers have outstanding eco-friendly performance. The flue gas emission of WNS series gas/oil-fired steam boilers can meet the environmental protection standards. Facing the strict low NOx emission requirements across the country, ZOZEN Boiler realizes the low emission of NOx (less than 30mg/Nm3) via the advanced low-nitrogen burner and combustion technology. ZOZEN WNS 20 tph steam boilers are applied in the food, chemical and nonferrous metal industries.
ZOZEN energy-efficient WNS series gas/oil-fired steam boilers have two-pass and three-pass structures. This series of boilers adopt the large-diameter corrugated furnace and threaded smoke tubes with high heat transfer efficiency. With the economizer at the end of the flue gas duct, they can enlarge the boiler's heating surface, lower the exhaust gas temperature to 60℃ and improve the boiler's thermal efficiency to over 98%. ZOZEN WNS 8 tph steam boilers are applied in the food, chemical and heating industries.
ZOZEN SZL series biomass-fired boiler has the characteristics of sufficient output and high thermal efficiency. To ensure the sufficient combustion of fuel and save the fuel costs, ZOZEN analyzes the characteristics of different fuels, and optimizes the feeding hopper, width and length of grate, grate rotating speed, secondary air inlet place and direction. ZOZEN also adopts the design of separate air chambers and air dampers to ensure the complete combustion of different biomass fuels and improve the boiler thermal efficiency to above 88%.
ZOZEN SZL series biomass-fired boiler can be fired by various kinds of fuel including biomass particles, wood chips, palm shells, straws and so on. The boiler body is composed of the chain grate and boiler proper with a packaged or pre-assembled structure. It is convenient for installation, so it can reduce the basic construction costs for customers. At the same time, in order to meet the boiler emission standards in different areas, ZOZEN Boiler can design the cyclone, wet scrubber and bag-type dust removal devices to lower the NOx emission to 200mg/m3.
ZOZEN SZS series steam boiler is a kind of D-type chamber structure boiler with longitudinal double drums. It has a big combustion chamber equipped with the low emission burner to effectively reduce the NOx. It also adopts the full membrane tube wall structure and pressurized combustion without smoke mixture.
ZOZEN 12 tph WNS series steam boiler is widely applied in the chemical, food, and other industries. The WNS series steam boiler is a kind of fire tube wetback boiler with a two-pass or three-pass structure. It is equipped with foreign advanced burner, economizer and condenser installed at the end of flue gas duct to lower the exhaust temperature to 60℃, achieve the thermal efficiency of over 98% and control the emission of NOx to less than 30mg/Nm3. It has the characteristics of compact structure, small covering area, short installation period, easy operation and complete automatic control system which can realize unattended operation.
ZOZEN 35 tph SZS series steam boiler is widely applied in the food, heating and other industries. The 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. 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.
