3 set coal fired hot water boiler applied to food factory, ZOZEN engineers developed the DZL series tri-drum biomass-fired boiler with Shanghai Jiaotong University

ZOZEN Boiler is a manufacturer of eco-friendly boiler equipment. Its gas-fired boiler series products have become the common choice of users in various industries such as Shandong Binzhou Xinkeode, Shandong Luhua, Shandong Guangyue Chemical, and provide support for the coal-fired boiler replacement work in Shandong Province.

In the process of smelting molten steel, pouring steel ingots, and producing finished castings, a large amount of steam is consumed. The superheated steam generated by the boiler provides the required thermal energy for its process. Through open bidding, ZOZEN stood out among many boiler manufacturing enterprises with its own technical advantages and quality assurance, and provided China Second Heavy Machinery Group Corporation with a large superheated steam boiler, 3 set coal fired hot water boiler applied to food factory.

ZOZEN DZL series coal-fired steam boilers are horizontal three-pass water-fire-tube chain grate boilers. Threaded smoke tubes are arranged in the drum to form a convection heating surface. The drum and the water-cooled walls on both sides form a furnace radiation heating surface.

ZOZEN biomass-fired boilers refer to the boilers fueled by biomass energy, which are typically energy-saving and eco-friendly products. Biomass fuel usually refers to the agricultural and forestry wastes such as various crop straws, leaves, wood chips and so on, which are renewable and recyclable. The operating cost of biomass-fired boilers is low, which is only a half of that of gas-fired boilers. However, the initial investment cost of biomass-fired boilers is higher than that of oil-fired or natural gas fired boilers. Biomass-fired boilers are good alternatives to gas-fired boilers when replacing the coal-fired boilers. At present, the technical parameters of biomass-fired boilers are 2-75 tph (rated capacity) and 2.0-116 MW (rated thermal power).

The waveform stove furnace is an important part of the WNS series of oil-fired/gas-fired boiler. This part is directly exposed to the radiation of high-temperature flame and erosion of high-temperature flue gas. The use of the axial expansion and contraction of waveform stove furnace can reduce the thermal stress generated by the shell, tube plate and furnace itself, and more importantly, reduce the stress concentration caused by the elongation of furnace at the connection between furnace and tube plate. At the same time, the waveform stove furnace strengthens the flue gas disturbance, effectively improves the heat transfer effect of unit area and volume, and further improves the thermal efficiency of boiler.

3 set coal fired hot water boiler applied to food factory, The steam boiler supplies adequate steam support for multiple production processes including drying, profiling and vulcanizing of the rubber industry. Jiangsu General Science Technology Co., Ltd. is a modern high-tech enterprise specializing in R&D, production and sales of tires, it built a new production base in Thailand in January 2019. After various comparisons and investigations, General Science ordered SZL series biomass steam boiler from ZOZEN, which has the advantages of compact structure, safety and efficiency, and sufficient output. 

Be it a firetube, watertube, hot water, or steam boiler, they are all effective and efficient in their own unique ways. To learn in more detail about the differences between boiler types, visit the section on ZOZEN website.
