A steam boiler system is one of the most critical components in industrial energy infrastructure, providing a stable and controllable source of steam for power generation, manufacturing, processing, and auxiliary plant operations. In industrial applications, steam is not only a heat carrier but also a key medium for energy conversion, process control, and system integration. The performance of a steam boiler system directly affects production continuity, operating efficiency, and overall project reliability.

Unlike a single piece of equipment, a steam boiler system refers to the coordinated operation of the boiler body, combustion equipment, fuel supply, flue gas flow, ash handling, and control systems. The system must be designed to maintain stable steam output under long-term operation while adapting to different fuels and load conditions. In biomass energy projects and industrial steam supply projects, the steam boiler system must also address challenges such as fuel variability, ash handling, and operational stability.

DZL Tri-Drum Biomass Steam Boiler System: System Characteristics, Technology, and Advantages

The DZL tri-drum biomass-fired boiler developed by ZOZEN BOILER is designed as a complete steam boiler system suitable for medium-capacity biomass energy and industrial steam projects. Unlike conventional single-drum or double-drum configurations, this boiler adopts a three-drum water tube structure, which enhances circulation reliability and system stability under continuous operation.

ZOZEN 15 ton DZL biomass-fired steam boiler

From a structural standpoint, the DZL tri-drum biomass steam boiler system consists of an upper assembly and a lower assembly, forming an assembled structure that facilitates transportation and installation. The boiler body itself is a water tube boiler composed of three drums, which are connected by water tubes to form a stable circulation loop. This design supports efficient heat transfer while ensuring reliable water circulation, which is essential for maintaining consistent steam parameters in a steam boiler system.

The boiler capacity range of this steam boiler system covers 15 to 40 tons per hour, with a working pressure range of 1.25 to 2.5 MPa. These parameters make the DZL tri-drum boiler suitable for biomass power generation projects and industrial applications requiring stable medium-pressure steam. The system design ensures that steam generation remains steady even during prolonged operation, meeting the strict requirements of industrial and energy-generation users.

As a third-generation biomass-fired boiler, the DZL tri-drum steam boiler system is specifically designed to address the ash accumulation issues that were commonly encountered in the convection areas of earlier double-drum biomass boilers. In this system, flue gas exits the furnace and enters the convection heating area in a way that allows dust and ash particles to fall directly into the ash hopper located at the bottom of the convection zone. This structural improvement significantly enhances the cleanliness and stability of the heat exchange surfaces, contributing to long-term operational reliability of the steam boiler system.

Combustion adaptability is another key feature of the DZL tri-drum biomass steam boiler system. Biomass fuels vary in composition, ash content, and combustion characteristics, which places high demands on furnace design and combustion equipment. To address this, the DZL system can be equipped with different types of grates based on the specific characteristics of the biomass fuel used. This flexibility ensures sufficient fuel combustion, stable heat release, and controlled ash discharge, all of which are essential for maintaining the efficiency and stability of the steam boiler system.

The system-level design also extends to operational longevity. By optimizing the combustion process and reducing localized ash accumulation, the DZL tri-drum steam boiler system helps prolong the service life of key components such as the grate and heating surfaces. This aspect is particularly important for biomass power generation projects, where the boiler is expected to operate continuously under demanding conditions.

Case Study: Biomass Steam Boiler System for HENDESE Group in Turkey

Turkey Hendese Group was established in Ankara, Turkey, in 2018 and has developed into a professional turnkey machinery contracting project company in the local market. With growing involvement in renewable energy projects, Hendese undertook a local biomass boiler power generation project that required a reliable and well-engineered steam boiler system.For this project, Hendese required a biomass-fired steam boiler system capable of meeting the operational demands of power generation while ensuring stable performance over extended operating periods. After evaluating potential suppliers, Hendese selected ZOZEN BOILER as the equipment provider for this project.

In response to the project requirements, ZOZEN BOILER supplied the DZL series tri-drum biomass-fired steam boiler system. This system was selected due to its water tube structure, stable circulation design, and proven adaptability to biomass fuels used in power generation applications.

The DZL tri-drum steam boiler system provided to Hendese adopts an assembled structure, divided into an upper part and a lower part, which facilitated on-site installation and integration into the overall power generation system. The three-drum water tube configuration ensured reliable water circulation and effective heat transfer, supporting stable steam output for the biomass power generation process.

One of the key advantages of this steam boiler system in the Hendese project is its ability to address ash-related challenges commonly associated with biomass combustion. As a third-generation biomass boiler, the DZL system improves ash handling in the convection area by allowing dust in the flue gas to fall directly into the ash hopper. This design helps maintain clean heat exchange surfaces and supports stable long-term operation, which is critical for power generation applications.

In addition, ZOZEN BOILER configured the grate system according to the characteristics of the biomass fuel used in the project. This ensured sufficient combustion and stable heat release, meeting the efficiency and stability requirements of the biomass power generation system without introducing unnecessary operational complexity.
