As the paper industry accelerates its shift toward low-carbon and environmentally responsible production, improving energy efficiency has become a key priority. This has also raised an important question for many producers: which biomass boiler manufacturer can deliver both reliable performance and real environmental benefits?

Recently, a large paper enterprise launched a major environmental upgrade project at its industrial park, selecting DZW series 25-ton/hour biomass reciprocating grate steam boiler supplied by ZOZEN Boiler. Fueled by agricultural and forestry residues, the system is expected to consume nearly 100,000 tons of biomass waste each year, replacing around 60,000 tons of standard coal and substantially reducing carbon dioxide emissions.

ZOZEN 25 Tons/Hour Biomass Reciprocating Grate Steam Boiler

To ensure smooth project implementation and meet demanding requirements for efficiency, stability, and environmental performance, ZOZEN Boiler supplied its third-generation DZW series biomass reciprocating grate steam boilers. The 25 Tons/Hour Biomass Reciprocating Grate Steam Boiler is a three-drum water-tube boiler designed specifically for large-capacity biomass applications.

One of its key strengths is broad fuel adaptability. The DZW series can effectively burn various biomass fuels, including loose biomass residues, construction wood waste, wood chips, and palm shells. This makes the 25 Tons/Hour Biomass Reciprocating Grate Steam Boiler particularly suitable for industrial parks with diverse and fluctuating biomass fuel sources.

Efficient and complete combustion is critical when dealing with high-moisture biomass fuels. ZOZEN Boiler addresses this challenge through a combination of a reciprocating grate and an independent air chamber structure. The reciprocating grate continuously moves and agitates the fuel bed, improving air penetration and heat release. At the same time, independent air chambers allow precise air distribution at different combustion stages.This design ensures that even biomass fuels with relatively high moisture content can burn thoroughly and steadily, maintaining reliable steam output from the 25 Tons/Hour Biomass Reciprocating Grate Steam Boiler.

Another notable feature of the 25 Tons/Hour Biomass Reciprocating Grate Steam Boiler is its high thermal efficiency, which exceeds 86.7%. ZOZEN achieves this through densely arranged water-cooled wall tubes and a customized boiler system configuration that expands the radiant heat transfer area inside the furnace.As a result, more heat is effectively absorbed and converted into usable steam, reducing overall fuel consumption and supporting the project’s energy-saving objectives. For large paper mills, this level of efficiency translates into substantial long-term operational savings.

By installing three units of the 25 Tons/Hour Biomass Reciprocating Grate Steam Boiler, the paper enterprise can make full use of local biomass resources, reduce reliance on coal, and significantly cut carbon emissions. At the same time, stable steam supply supports continuous papermaking operations and consistent product quality.This project highlights how biomass boiler technology can align environmental responsibility with economic practicality in large-scale industrial applications.
