In the realm of industrial production, the demand for large-capacity boilers continues to rise, especially among enterprises that require stable and high-efficiency steam output for continuous operations. Among all the available capacities, the boiler 20 ton model stands out as a cornerstone for medium to large-scale industrial processes. Its ability to deliver a consistent and sizable steam supply makes it a preferred solution for industries such as food and beverage, textile, chemical, building materials, and pharmaceuticals.

The 20 ton boiler is not just about capacity—it represents an equilibrium between energy input and output efficiency. For enterprises focused on maintaining production stability while optimizing fuel consumption, the 20 ton steam boiler acts as a reliable thermal backbone. In this context, ZOZEN Boiler, a leading industrial boiler manufacturer with decades of experience, has become a trusted partner for businesses seeking high-performance solutions. With a strong global presence and a reputation for technical excellence, ZOZEN’s offering of boiler 20 ton configurations, particularly the SZL series coal-fired steam boiler, is reshaping what industries can expect from modern thermal equipment.

ZOZEN Boiler: High-Efficiency and Tailored for Performance   

ZOZEN BOILER’s SZL series coal-fired steam boiler exemplifies advanced engineering for industries requiring robust, high-capacity thermal systems. Designed as a double-drum, chain grate water-tube boiler, it combines structural durability with adaptive combustion technology to ensure stable steam output and fuel flexibility.The SZL series boilers can adapt to various types of coal through customizable furnace design. ZOZEN Boiler uses customized boiler system and close-packed water-cooled wall tube structure to achieve thermal efficiency >81%. The design of independent air chamber ensures full combustion of fuel. The integrated intelligent control system can monitor temperature, pressure and water level to ensure seamless operation with minimal human intervention.

The SZS gas boiler embodies ZOZEN Boiler’s expertise in efficient steam production for natural gas users. This double-drum, longitudinal boiler uses a membrane water-cooled wall + large furnace design to improve heat transfer efficiency, and an economizer to reduce exhaust gas temperature. The system thermal efficiency is >100%. Its low NOx burner system can control NOx emissions below 30 mg/Nm3, meeting strict environmental standards. In addition, the boiler uses an advanced control system to reduce operating and maintenance costs, and achieves fully automatic and safe operation through boiler IoT + remote control + expert management.

For biomass applications, ZOZEN DZL non-ashing biomass boiler solves the problem of ash accumulation and incomplete combustion. This three-drum chain grate water pipe 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. The DZL series fuel has a wide adaptability and can be used for biomass pellets, rice husks, wood chips, corn cobs, sawdust, etc. It has an advanced control system, a high degree of automation in fuel supply, ash discharge, and slag discharge, and is easy to operate and run, with a thermal efficiency of >88%.

Each ZOZEN boiler series—SZL, SZS, and DZL—is engineered to balance performance, adaptability, and environmental compliance, empowering industries to achieve sustainable growth.

Boosting Dairy Production Efficiency with ZOZEN’s SZL Boilers

One compelling example of the performance and adaptability of ZOZEN’s boiler 20 ton configuration comes from a leading dairy processing company. In the dairy industry, steam plays an indispensable role throughout crucial production stages such as milk preheating, pasteurization, and cooling. The process requires a reliable steam supply with consistent pressure and temperature to protect product quality and ensure sanitary standards are met.

Faced with growing production volumes and increasingly stringent hygiene regulations, the dairy enterprise sought to upgrade its thermal system. ZOZEN, recognized for its industry-specific solutions and deep expertise in combustion engineering, became the natural choice. The company selected two SZL20-1.6-AII coal-fired steam boilers from ZOZEN—each with a capacity of 20 tons per hour.

To address the specific coal quality used by the company, ZOZEN engineers meticulously customized the boiler design. The solution included the use of a water-cooled arch structure and a tailored furnace layout.Additionally, independent wind chambers were integrated to ensure uniform air distribution and complete coal combustion.

This precision engineering translated directly into production advantages. The dairy company now enjoys a significantly more stable steam supply, with the boilers operating efficiently even under high-load conditions. The improved combustion efficiency also resulted in lower fuel consumption and reduced emissions. The plant’s annual fresh milk processing capacity has now reached 1 million tons—an achievement made possible, in part, by the dependability and performance of ZOZEN’s SZL boiler 20 ton units.

Selecting the Right 20 Ton Boiler: Why ZOZEN is the Preferred Choice

When industrial enterprises evaluate boiler systems, choosing the right capacity is only the first step. The real challenge lies in identifying a solution that aligns with the fuel type, operational demands, and long-term efficiency goals of the enterprise. The boiler 20 ton model, particularly when backed by ZOZEN’s engineering expertise, emerges as a compelling choice for businesses seeking to enhance production while maintaining economic and environmental sustainability.

ZOZEN’s extensive experience across industries allows it to deliver solutions that are not only technically sound but also tailored to real-world production needs. The company’s commitment to innovation, quality control, and customer support ensures that each boiler 20 ton installation delivers optimal performance from day one.
