ZOZEN 36 TPH Reciprocating Grate Biomass Steam Boiler for Paper Industry

Jinzhou Chenhong Paper Co., Ltd. is a major paper product manufacturer in North China. During the production process, steam is the key energy source for drying, forming, and other core steps, which places high demands on the boiler’s stability, fuel adaptability, and thermal efficiency. The company had long struggled with the challenges of high-moisture biomass fuel, incomplete combustion, and low thermal efficiency.

Traditional boilers are unable to efficiently burn high-moisture loose biomass, often requiring additional drying processes that increase costs. Incomplete combustion leads to energy wastage and high steam costs.

To address these industry challenges, ZOZEN Boiler provided a tailor-made DZW series reciprocating grate biomass steam boiler, leveraging core technologies to solve these problems:

Reciprocating Grate: The unique mechanical movement powerfully stirs and loosens the fuel layer, effectively breaking up clumping and slagging caused by high-moisture fuel. This ensures continuous and even fuel advancement.
Independent Air Chamber Design: Precisely segmented air supply is provided along the length of the grate. The system delivers tailored airflow and temperature to different stages of fuel drying, combustion, and burnout, significantly improving ignition and burnout for high-moisture biomass. This eliminates the need for separate fuel drying.
