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 Boiler cooperated with Hebei Yigao Bioenergy Co., Ltd. to improve the reasonable and efficient utilization of biomass energy such as corn straws and so on. According to Hebei Yigao Bioenergy’s requirement of using biomass straws as fuel, ZOZEN Boiler reasonably designed the furnace arch, furnace wall and furnace heating surface of SZL series biomass-fired steam boiler by cooperating with Shanghai Jiaotong University to ensure the combustion efficiency and rated evaporation capacity of boiler.
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.
ZOZEN longitudinal seam welding adopts advanced submerged arc automatic welding technology to ensure welding quality. After the pre-welding treatment, ZOZEN uses automatic argon arc welding technology to complete the butt welding of steel pipes, and performs X-ray real-time imaging of the welds to prevent unqualified welds from entering the next production process. The advanced automatic welding machine completes the automatic welding of the longitudinal seams under the tracking of the photoelectric system, which not only improves the efficiency but also effectively guarantees the welding quality.
The condition of the factory during the outbreak of coronavirus. Although the outbreak of coronavirus has caused a certain influence on the personnel flow, logistics and transportation. ZOZEN has well prepared the epidemic prevention work and materials, workers wear masks every day while working. With high-efficient running of the automatic production lines and adequate stocking of raw materials, the factory has returned to normal operations quickly.
SZL series vertical dual drums chain grate water tube steam and hot water boiler, adopts quick fitting and assembly structure. The 4-6t/h boiler is of quick fitting tube structure, exit shop after completely assembled, the boiler of 6-35t/h is composed of 2 main components. The upper assembled component is the boiler proper heat absorbing part, and the lower assembled component is of combustion equipment. The former part of the boiler proper is arranged a membrane wall, the upper part of it is connected to boiler cylinder, and its lower part is connected to collective chest, so as to form a combustion room and absorb the radiated heat from the furnace. Its rear part is arranged with dense convection tubes between upper and lower boiler cylinders. The high temperature smog after combustion shall stand for twice returning flushing transversely to the heat accepting surfaces, and shall be introduced to coal saver singly arranged, and flow into duster and exhausted from chimney in the end.
