How ZOZEN Enhances Typical Biomass Boiler Efficiency

Understanding Typical Biomass Boiler Efficiency
The efficiency of a biomass boiler, often referred to as the typical biomass boiler efficiency, is a crucial metric that determines how effectively the boiler converts biomass fuel into usable energy. This efficiency is calculated based on the energy content of the fuel and the boiler’s ability to transfer this energy into steam.

For instance, in a wood-fired biomass boiler, the fuel consumption is directly related to the calorific value of the wood. Let’s consider wood with a calorific value of 4000 Kcal/kg. A biomass boiler with a steam output of 1 ton per hour typically requires about 600,000 Kcal of energy per hour.

Moreover, the combustion efficiency of the equipment significantly impacts the typical biomass boiler efficiency. High-efficiency biomass boilers can more effectively utilize the energy content of the fuel, minimizing energy losses and thereby enhancing the typical biomass boiler efficiency. ZOZEN’s biomass boilers are designed with customized feeding systems tailored to the fuel characteristics, reducing heat energy losses in combustion, heat dissipation, and flue gas emissions. ZOZEN’s measured system thermal efficiency is ≥88%, which is 5% higher than the typical biomass boiler efficiency.

In the aforementioned example, the actual fuel consumption for a ZOZEN biomass boiler would be 600,000 / 4000 / 88% = 171 kg. Thus, ZOZEN’s biomass boilers outperform the typical biomass boiler efficiency, making them a reliable choice for your energy needs.

ZOZEN’s Biomass Steam Boiler Products
ZOZEN offers a comprehensive range of biomass steam boilers across three main series: DZL series longitudinal chain grate boilers, SZL series double-drum longitudinal chain grate boilers, and SHL series bulk biomass fuel boilers. These boilers are highly adaptable to various biomass fuels, including biomass pellets, wood chips, palm shells, and straw. Here, we highlight the DZL and SZL series.

DZL Series Longitudinal Chain Grate BoilersThe DZL series biomass steam boilers are horizontal three-pass water-fire tube chain grate boilers, delivered as a whole for quick installation and ease of use.
Thermal Capacity: 2 – 10 t/h
Efficiency Features:
Utilizes advanced threaded smoke tubes, manufactured with an automated spinning process, providing a heat transfer coefficient 1.8 times higher than ordinary smoke tubes, thus achieving an overall efficiency higher than the typical biomass boiler efficiency.
The high volatile content and low ash content of biomass fuel mean minimal ash residue on the grate post-combustion. ZOZEN selects high-temperature resistant grate materials to accommodate these combustion characteristics, significantly enhancing grate reliability.

DZL Series Three-Drum Biomass Steam Boilers
The DZL series also includes a three-drum biomass steam boiler, a unique ZOZEN design with proprietary technology:
Thermal Capacity: 15 – 40 t/h
Efficiency Features:
Boiler furnace water walls extend down to the grate, increasing the boiler height and furnace volume, resulting in overall efficiency higher than the typical biomass boiler efficiency. This design also effectively controls the furnace temperature below 850°C, reducing NOx formation and improving environmental performance.
Innovative structure addressing the traditional accumulation issues of double-drum boilers, with two lower drums on each side and an ash hopper in the middle, directing dust to the bottom ash hopper.

SZL Series Double-Drum Longitudinal Chain Grate Boilers
The SZL series boilers are designed based on international advanced technology and experience, featuring a double-drum layout that ensures optimal combustion and thermal efficiency.
Thermal Capacity: 6 – 35 t/h
Efficiency Features:
Ensures the optimal excess air volume and temperature across combustion zones, allowing for the complete combustion of biomass’s high volatile content, achieving an efficiency significantly higher than the typical biomass boiler efficiency.
Includes an anti-flame return device at the furnace inlet to prevent backfire, ensuring operational safety and fuel efficiency.

ZOZEN’s Collaboration with the Pharmaceutical Industry
ZOZEN has significantly invested in technological innovation, leading to successful collaborations across various industries, including pharmaceuticals. A notable example is a recent project with a pharmaceutical company that required efficient and reliable steam generation for its operations.

The company chose ZOZEN’s DZL4-1.25-T biomass steam boiler, a horizontal three-pass water-fire tube chain grate boiler known for its compact structure and ease of installation. Post-installation, the company expects substantial growth, attributing it to ZOZEN’s superior boiler performance. Feedback highlighted ZOZEN’s meticulous installation process and comprehensive training for operational staff, ensuring smooth and efficient boiler operation. The energy-saving capabilities of ZOZEN’s boiler, surpassing the typical biomass boiler efficiency.
