A paper packaging plant in Hubei has adopted a 6 t/h SZL series biomass steam boiler from Zozen Boiler to provide stable steam for pulping and paper machine drying. The unit pairs a chain grate with independent air chambers to enable zoned air regulation and complete combustion. Its furnace features closely spaced water-cooled walls with a large radiant heating surface, combined with a customized boiler system, achieving thermal efficiency >86%. While ensuring steam quality and continuous supply, it can utilize multiple fuels—biomass pellets, rice husks, wood chips, corn cobs, and sawdust—significantly reducing fuel costs and carbon emissions, helping the plant meet both energy-saving and environmental goals.
Food production enterprises utilizing ZOZEN coal-fired boilers and biomass boilers achieve lower energy consumption and higher production efficiency. The design of these boilers prioritizes environmental protection, significantly reducing the environmental impact of emissions through advanced dust removal and purification systems, complying with increasingly stringent environmental protection standards.
The ZOZEN SZS series gas/oil-fired boiler workshop is a bustling hub of activity, with skilled technicians and engineers working together to produce some of the industry's most advanced and efficient boilers. The workshop is filled with state-of-the-art machinery and equipment, including automated welding systems, precision cutting tools, and computer-controlled testing equipment. The technicians work meticulously to ensure that every component of the boilers meets the highest standards of quality and safety, from the smallest bolt to the largest furnace.
ZOZEN is a large industrial boiler manufacturer specializing in the supply of oil-fired boilers, gas-fired boilers, biomass-fired boilers, coal-fired boilers, circulating fluidized bed boilers and organic heat carriers. ZOZEN pays special attention to product quality, and introduces 600 sets of advanced tooling equipment to realize large-scale and modern production.
The user undertakes the winter heating in the entire township. The gas-fired hot water boilers in this project are SZS series water tube boilers with reasonable structure design and safe and reliable operation.
The autoclaved curing process of building materials in the project needs a lot of steam support, and requires stable steam supply. ZOZEN technicians designed a set of biomass boiler that is not easy to coke and accumulate ash. By adjusting the internal structure of the boiler and changing the arrangement of the drum, the dust in the flue gas can directly settle into the ash hopper at the bottom of the convection zone when the flue gas enters the convection zone from the furnace outlet.
Water pressure test of boiler is the test of strength and tightness of boiler or components with pressure water after assembly. The main purpose of the water pressure test is to identify the tightness and compressive strength of the boiler pressure parts, including but not limited to whether the welds, flange joints and pipe expansion joints are tight without leakage, and visually observe the deformation of the pressure parts.
ZOZEN provides a set of 15 tons superheated steam boiler for a paper making company in China. The boiler is the SZS series, it is designed with the superheater to raise the temperature to meet the demand.
