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.
Under the general trend of global economic green development, biomass-fired boilers use biomass-forming pellets such as crop straws and forestry residues as fuel have become the choice of many enterprises because of their environmental protection advantages. Among them, Hunan Leading Construction Technology Co., LTD., specializing in the R&D, production and sales of lightweight building materials, is an integrated supplier of various advanced application technologies. In the production process of high-precision aerated concrete blocks and plates, ZOZEN SZL series biomass-fired boilers provide a stable heat source for the autoclave curing process.
The chain grate boiler is a grated fired boiler with a high degree of mechanization, the chain grate is the combustion equipment. The working principle is to drive the chain grate to rotate by the reducer, so that the solid fuel can be fired from the front to the end of the boiler, and the combustion efficiency is greatly improved compared with the fixed grate. When the chain is turned to the bottom, the air cooling lower the temperature, which can protect the grates from burning loss.
This series of double-drum steam boilers adopts a full membrane wall structure with good sealing performance. It is designed with large furnace to ensure full combustion of fuel and the thermal efficiency is over 98%. Meanwhile, this series of gas-fired steam boilers has reliable water circulation. Besides, the arrangement of various safety devices such as explosion-proof doors and flame detectors make the boiler operation safer and more reliable.
WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
