In the world of industrial energy systems, the water tube boiler has emerged as a cornerstone of high-efficiency steam generation. Unlike traditional fire-tube boilers, where hot gases pass through tubes surrounded by water, a water tube boiler circulates water through tubes heated externally by combustion gases. This design enables rapid steam production, higher operating pressures, and greater adaptability to fluctuating thermal demands. As industries increasingly prioritize energy efficiency, environmental compliance, and operational flexibility, the water tube boiler has become a preferred solution across sectors such as chemical processing, textile manufacturing, power generation, and food production.

A water tube boiler operates on the principle of separating water and steam within a network of tubes, which are heated by combustion gases flowing externally. This configuration allows for precise control over steam quality and pressure, making it ideal for applications requiring high-temperature, high-pressure steam.

Industries reliant on continuous thermal energy—such as petroleum refining, papermaking, and synthetic fiber production—leverage water tube boilers to meet their demanding steam requirements. Their ability to integrate with advanced flue gas treatment systems further positions them as a sustainable choice for facilities aiming to reduce emissions and comply with environmental regulations.

ZOZEN BOILER: Pioneering Water Tube Boiler Technology  

ZOZEN Boiler is a leader in designing and manufacturing water tube boilers that meet a variety of industrial needs. Its flagship products include the SZL series biomass steam boiler, the DZL series non-ash biomass steam boiler and the DZW series non-ash reciprocating grate biomass boiler, each of which is carefully designed to provide excellent performance, reliability and sustainability.

The SZL series biomass boiler is a chain grate water tube boiler designed by ZOZEN based on international advanced technology and experience. It adopts a horizontal double drum and longitudinal layout structure. It can be used for biomass pellets, rice husks, wood chips, corn cobs, sawdust, etc., and has a wide range of fuel adaptability.

The DZL series non-ash biomass boiler is a water tube boiler composed of three drums. It is a biomass boiler independently developed by ZOZEN Boiler and has independent intellectual property rights. The boiler adopts an assembled structure, consisting of two large parts, the upper large part is the main heating surface, and the lower large part is the combustion equipment. At the same time, a sootblower is arranged on the tail convection heating surface, and a sootblower hole is left on the top of the furnace body. The sootblowing type is selected according to different fuels, and soot can be cleaned without stopping the furnace.

The DZW series reciprocating grate biomass boiler represents the innovation of ZOZEN’s third-generation biomass water tube boiler technology. The series adopts a reciprocating grate mechanism to improve fuel flexibility and combustion efficiency, and the actual operating thermal efficiency is 10% higher than that of ordinary biomass boilers. Its automated operation – including functions such as self-regulating fuel supply, automatic sootblowing and ash discharge system – reduces labor demand and ensures stable performance, making it an ideal choice for continuous industrial production.

Powering Plastic Foam Production with DZW Series Biomass Boilers

The plastic foam industry, known for its energy-intensive production cycles, demands a water tube boiler capable of delivering uninterrupted thermal energy while balancing cost and environmental impact. A leading manufacturer in this sector faced significant challenges with its aging boiler system, which struggled to maintain stable steam supply for continuous foam extrusion and molding processes. The facility also sought to reduce fuel costs and comply with tightening emissions regulations.

After evaluating multiple water tube boiler options, the company selected ZOZEN’s DZW series reciprocating grate biomass boiler. This decision was driven by the boiler’s ability to:

– Enhance Thermal Efficiency: The DZW series’ fourth-generation combustion technology achieved a 10% improvement in thermal efficiency compared to conventional biomass boilers, directly reducing fuel consumption.

– Ensure Operational Stability: Automated systems for fuel feeding, soot blowing, and ash removal minimized manual intervention, lowering the risk of production disruptions caused by human error.

– Support Cost Optimization: By utilizing locally sourced biomass fuels, the facility lowered energy costs while maintaining consistent steam quality for critical foam production processes.

Following installation, the DZW series boiler not only resolved the facility’s steam supply issues but also reduced operating costs. The water tube boiler’s robust design and automated controls allowed the plant to maintain peak productivity, even during high-demand periods, while aligning with its sustainability goals.
