Boiler 15 Ton: Industrial Applications and ZOZEN Boiler Solutions

In modern industrial operations, steam is a fundamental energy source that supports production processes across multiple sectors. The boiler 15 ton is a common choice for enterprises that require medium-to-large scale steam capacity, offering stable output and the flexibility to adapt to a variety of fuels and industrial needs. With steam capacities sufficient to power food processing, textiles, paper production, chemicals, tobacco, and building materials industries, a 15-ton boiler provides the balance between efficiency and practicality. Its scale ensures that businesses can meet fluctuating production demands while maintaining reliable energy supply.

Chinese manufacturers have become important players in the global boiler market, with ZOZEN Boiler recognized as one of the leading companies in the industry. By integrating modern manufacturing technologies, advanced combustion systems, and strict quality control, ZOZEN has successfully provided boiler 15 ton solutions to customers worldwide. The company’s portfolio includes coal-fired, biomass-fired, and oil/gas-fired boilers, all of which can be customized for specific operational requirements.

ZOZEN SZL, DZL, and SZS Series for the Boiler 15 Ton Category

The SZL series is a water-tube, double-drum chain grate steam boiler designed for large-scale applications, including the boiler 15 ton capacity. Its longitudinal arrangement ensures compact structure and strong adaptability to different types of coal. The SZL boiler is assembled in sections, allowing for simplified transportation and short installation cycles on-site.The furnace is equipped with large water-cooled walls, enhancing radiant heat absorption and reducing heat loss. Independent air chambers beneath the grate ensure precise air distribution, enabling complete coal combustion even with varying calorific values. The SZL series integrates convection heating surfaces, economizers, and air preheaters, helping the system achieve a thermal efficiency of around 81%. For the tobacco, paper, and textile industries, where continuous steam flow is essential, this design offers both reliability and energy efficiency.

In the biomass category, ZOZEN has engineered the DZL three-drum chain grate steam boiler. As part of the boiler 15 ton range, this model is particularly suited to industries where agricultural residues and wood waste are readily available. The three-drum design ensures efficient water circulation, stable steam output, and strong adaptability to biomass fuels such as rice husks, corn stalks, and sawdust.The threaded smoke tubes and arched tube plate structure expand the heat transfer area and eliminate stress concentration, effectively solving common issues like tube plate cracking. With a thermal efficiency above 88%, the DZL three-drum biomass boiler reduces both operating costs and environmental impact, supporting industries that aim to combine production efficiency with sustainability.

For enterprises seeking a clean and highly automated option in the boiler 15 ton segment, ZOZEN offers the SZS series oil and gas-fired steam boiler. This model is designed as a water-tube, double-drum, D-type arrangement with full membrane wall construction. The large combustion chamber allows for complete fuel burning, while the low-NOx burner configuration ensures emissions compliance with stringent environmental standards.The SZS series achieves design thermal efficiency up to 98%, thanks to its optimized furnace volume and advanced heat recovery equipment such as condensers and economizers. Steam capacities in the 15-ton range are widely used in industries such as food processing, chemicals, and pharmaceuticals, where precise steam parameters are crucial for product consistency. Full automation enables remote control, real-time monitoring of pressure and temperature, and safe operation with minimal manual intervention.

Case Study: Tobacco Industry Project

Steam boilers are critical in the tobacco industry, particularly in processes such as leaf conditioning, humidification, and re-drying. A large state-owned tobacco enterprise recently launched a project to upgrade its processing technology and auxiliary equipment, aiming to improve efficiency and product quality. Given the intensive steam demand during production, the company required a reliable and high-capacity solution.

After evaluating several options, the enterprise selected ZOZEN to provide a boiler 15 ton system tailored to its needs. ZOZEN delivered an SZL series coal-fired steam boiler, specifically a horizontal, double-drum, longitudinal chain grate design. This assembled unit allowed for convenient installation on site with a shortened construction period, ensuring that the project was completed on schedule.

The design of the boiler incorporated advanced combustion technology and water-cooled wall structures to ensure high thermal efficiency and reliable steam supply. During commissioning, the boiler achieved stable operation and met the enterprise’s requirements for leaf conditioning and re-drying processes. The client expressed confidence in ZOZEN’s technical strength and appreciated the timely service provided by the company’s engineers throughout installation and start-up.
