A: ZOZEN Boiler offers two pathways at 2 t/h depending on the dominant fuel. For coal as the main fuel, choose the DZL series coal-fired steam boiler (2–10 t/h, 1–2.5 MPa, 170–225 °C). It is designed for bituminous coal, lean coal, and anthracite, with stable chain-grate combustion and robust heat-transfer surfaces.
A: If wood or agricultural residues are primary, select the DZL series biomass-fired steam boiler (2–10 t/h). It supports biomass molding granules, wood ...
A: For challenging fuels, ZOZEN Boiler recommends the DZL or SZL series coal-fired steam boilers with engineering customization. At 10 t/h, ZOZEN Boiler’s SZL series (bi-drum, 6–35 t/h) is suitable for higher loads and variable coal quality; DZL (2–10 t/h) fits compact layouts. Working pressure options are typically 1–2.5 MPa with outlet temperatures around 170–225 °C.
A: To handle low-cal, high-sulfur, high-moisture coal, ZOZEN Boiler can optimize furnace volu...
What are the procedures and formalities for the retrofit of a coal-fired boiler?
The procedures and formalities for retrofitting a coal-fired boiler can vary depending on the specific regulations and requirements of the region or country. However, there are some general steps that are typically involved in the retrofit process:
1. Feasibility Study: The first step is to conduct a feasibility study to assess the technical and economic viability of the retrofit project. This invo...
ZOZEN Boiler reduces operating costs in a circulating fluidized bed coal fired power plant by optimizing fuel flexibility, improving thermal efficiency, and minimizing maintenance. The CFB’s ability to use low-cost, low-grade coals and alternative solids is amplified by ZOZEN’s furnace and cyclone design, which maintains complete combustion across variable fuels, reducing unburned carbon losses and slagging.
Enhanced heat transfer surfaces—economizers, air preheaters, and well...

When evaluating boiler manufacturers in Georgia for coal-fired steam boiler solutions, it’s essential to identify which manufacturer offers the best value, durability, and environmental stewardship. Among all boiler manufacturers in Georgia, ZOZEN Boiler has consistently emerged as a preferred choice due to its robust technology and customer-centric approach.
Unlike some boiler manufacturers in Georgia, ZOZEN Boiler leverages advanced coal combustion technologies, providing highly efficie...
In the realm of industrial boilers, economizers play a pivotal role in enhancing efficiency and reducing fuel consumption. Essentially, a boiler economizer captures waste heat from boiler flue gases and uses it to preheat the feedwater before it enters the boiler. This process significantly improves the overall efficiency of the boiler system by reducing the need for the boiler to heat the water from a lower temperature. But, how long can one expect an economizer to last?
Lifespan of Boiler Eco...
