SZL series chain grate boiler can burn both the coal fuel and the biomass fuel. The boiler capacity is 4 tons to 35 tons. ZOZEN SZL series biomass-fired steam boiler has the advantages of compact structure, safe operation, high efficiency and sufficient output.
ZOZEN Boiler has optimized the three-pass gas and oil boiler to the two-pass type. The corrugated furnace with major diameter and the threaded smoke tubes enhances the heat transfer efficiency. The thermal efficiency of the boiler reaches over 98%. Also, the low-NOx burner could control the emission below 30mg/Nm³, which meets the environmental protection policy. ZOZEN WNS series gas/oil-fired boiler is well received by industrial plants due to its compact structure and packaged delivery with convenient installation.
There’s a growing demand for the industrial boilers in Pakistan, ZOZEN Boiler owns a professional international trade team, which can provide all-round high-quality boiler services for enterprises at home and abroad. ZOZEN Boiler not only has the ability to contract the whole process of boiler design, production, transportation, installation and delivery, but also provides after-sales services such as return visit and maintenance. Recently, a set of 20-ton chain grate boiler was delivered from ZOZEN Boiler to the plant in Pakistan.
The industrial oil-fired boiler can choose different kinds of fuels, such as the heavy oil, light oil and diesel, etc. The boilers need to be equipped with oil storage tank to store the fuel. ZOZEN Boiler contributes to developing the boiler system for more than 30 years. ZOZEN boiler has optimized the oil tank structure to improve the performance.
Chain grate is a common mechanized combustion device, which is used in biomass-fired boilers, coal-fired boilers and thermal oil heaters. ZOZEN chain grate is designed and produced independently, with reasonable structure and exquisite material selection.
Boiler header is a kind of large-diameter pipe connecting several heating surface pipes. It is made of seamless steel pipes with welding heads at both ends, and there are many pipe holes on the header body for welding or expanding pipes. The boiler header collects or distributes the steam-water working medium, to reduce the transmission connecting pipes of working medium and the number of tappings in the drum, which can improve the safety of the drum.
Membrane wall refers to the water wall composed of airtight tube screen welded by flat steel and pipes. Membrane wall can ensure that the furnace has good air tightness, which can significantly reduce the air leakage coefficient of the furnace and improve the combustion conditions in the furnace for negative pressure boilers.
According to different capacities and performance parameters, the delivery method of the boilers can be divided into three types: package delivery, assembled delivery and delivery in bulk. The assembled boiler is divided into combustion chamber and convection tube bundle area. This gallery focuses on the combustion chamber part of the boiler.
