Waste heat boiler refers to a boiler that heats water to a certain temperature by using the waste heat from waste gas, waste materials or waste liquid in various industrial processes and the heat generated by the combustion of combustible materials. Through waste heat recovery, hot water or steam can be produced to supply other sections. The waste heat boiler designed and manufactured by ZOZEN Boiler is mainly used as one of auxiliary machines of boiler system. By recovering the high-temperature flue gas from the boiler, the exhaust temperature is reduced, thus further improving the overall thermal efficiency of the boiler.
ZOZEN Boiler is a professional industrial boiler manufacturer integrating design, production, sales and service. The company has advanced production technology and equipment, including 600 sets of high-speed CNC plane drills, CNC drum drills, 4-axis CNC pipe benders, serpentine pipe production lines and membrane wall production lines. The major components of the boiler have been professionally and massively produced, and most of the products can meet the needs of customers for short-term delivery.
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.
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.
ZOZEN Boiler conducts the process inspection, which is the standard to check whether the boiler process flow operates and produces according to regulations. ZOZEN Boiler requires the inspection covering the whole plant, correcting the problems accurately in time, improving the quality awareness of workers, and examining the inspectors to improve the quality inspection professionalism, then improving the quality of boiler products.
