Among many boiler types, biomass-fired chain grate boiler has the advantages of wide fuel adaptability, low original emission concentration, low operating costs and easy operation. Based on the eco-friendly development thinking, ZOZEN Boiler has long been designing and manufacturing the chain grate boilers. At present, the DZL series industrial boiler adopts the advanced arch design, independently developed membrane water-cooled wall structure, special slag removal technology and reasonable sealing grate structure, which shows an obvious performance advantage.
In Sri Lanka, a set of ZOZEN 15 tph DZW series biomass-fired steam boiler was being installed and debugged. The user is a well-known local palm oil manufacturer, AEN PALM OIL PROCESSING (PVT) LTD. The boiler fuel is palm fiber. The boiler is a tri-drum boiler which has characteristics of no ash accumulation, high efficiency and good environmental protection performance. There is no need to stop the boiler for dust removal, which can make the boiler keep the normal operation for a long time. Meanwhile, considering the combustion characteristics of palm fiber, ZOZEN technicians also optimize the feeding hopper, furnace arch and air distribution device of the boiler to solve the coking problem caused by the fuel combustion.
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.
ZOZEN 10 tph SZL series steam boiler is widely applied in the nonferrous metals, pharmaceutical, printing and dyeing and other industries. The SZL series coal-fired/biomass-fired steam boiler is packaged or shop-assembled boiler with double drums and a chain grate stoker structure. The 4-6 tph boiler is a packaged structure and the 6-35 tph boiler is a shop-assembled structure. It is composed of 2 parts. The upper part is heat absorbing surface and the lower part is combustion equipment.
DZL series hot water boiler is horizontal three-pass water-fire tube chain grate boiler. It uses fuel like coal and biomass pellets. The thread smoke tubes inside the drum form the convention heating surface while the drum and two-side water-cooled wall form the furnace radiation heating surface. Its boiler structure is compact. It can be packaged before shipment which can reduce the costs of basic boiler construction. Therefore, it is a kind of popular heating equipment among hotels, schools and hospitals.
This is the modern production base of Wuzi ZOZEN Boilers Co., Ltd with 12 workshops and more than 150,000 square meters overall floorage. ZOZEN possesses digitized and automatic boiler production lines that can produce four series of products: gas-fired or oil-fired boiler, coal-fired boiler, biomass-fired boiler and thermal oil heater.
