Experience the versatility of ZOZEN’s DZL series boilers, featuring a unique water-fire tube design. The three-pass design in water-fire tube boilers is an innovative solution aimed at addressing the issue of tube plate cracking in conventional fire-tube boilers. This design increases the contact area between water and fire, enhancing thermal efficiency while also reducing thermal stress on the tube plates, thereby mitigating the risk of cracking.
DZL series coal/biomass boiler is a small chain grate boiler, which is delivered from the factory in the form of whole quick package. The boiler body is longitudinally arranged with a single drum, the threaded pyrotechnic tube is arranged in the drum to form a convection heating surface, and the drum and the water walls on both sides form a radiant heating surface of the furnace, so that the heat transfer efficiency is high.
In a textile mill in Nantong, ZOZEN DZL biomass boiler is providing stable heat energy for the production line. DZL series biomass boilers are reasonably arranged with furnace arch, furnace wall and furnace heating surface, so that the output is sufficient and the thermal efficiency is over 88%.
Reliable service is an important link to improve boiler performance and prolong its life. During the construction of biomass reciprocating grate boiler project in a project, ZOZEN's after-sales staff paid a number of on-site visits to guide and promote the smooth development of the project.
ZOZEN gas-fired thermal oil heater adopts multi-pass disc tube design, with sufficient heating surface and high heat exchange efficiency. At the same time, ZOZEN thermal oil heater adopts automatic control system, and the parameters such as oil temperature and pressure are automatically adjusted, and the smoke exhaust temperature and oxygen content are monitored in real time, which is used to optimize combustion and safety interlock.
The debugging of biomass boiler is an important step to ensure the stable and economic operation of the boiler, which is time-consuming and labor-intensive, with high technical requirements. ZOZEN service personnel gave on-site guidance, first of all, cold commissioning of biomass boiler, and cold calibration of boiler body water pressure test, pressure gauge, flow meter, safety valve and various interlocking protections.
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 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.
