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 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.
The steam boilers in the hospital are mainly used for sterilization and have certain requirements for the quality and quantity of steam. This time, Shandong Jining Psychosis Prevention and Treatment Hospital purchased two sets of WNS series gas-fired steam boiler from ZOZEN Boiler. This series of boiler has a wide fuel adaptability including natural gas, coal gas, biogas and so on. It also adopts the large-diameter corrugated furnace to ensure the sufficient combustion of fuel and the high thermal efficiency of over 98%. Equipped with the imported low-nitrogen burner, it can easily realize the ultra low NOx emission.
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 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.
