In today’s industrial landscape, energy systems must balance efficiency, environmental responsibility, and stable output. The boiler 2 ton has become a popular choice for medium-scale production lines that require steady steam for daily operations. With a capacity designed to meet the needs of food processing, feed manufacturing, textiles, paper production, pharmaceuticals, and light chemical industries, the 2-ton boiler offers flexibility and reliability without excessive investment in infrastructure.

The boiler 2 ton is valued for its ability to provide continuous steam output while maintaining compact dimensions that suit small to mid-sized facilities. Its operational scale makes it ideal for enterprises upgrading from outdated equipment or those needing efficient steam support for specific production lines. Within this field, ZOZEN Boiler has built a strong reputation for delivering advanced solutions. With decades of manufacturing experience and continuous innovation in combustion technology, welding techniques, and automation systems, ZOZEN Boiler has supplied boiler 2 ton systems to clients across Asia, Europe, and beyond, ensuring both energy efficiency and compliance with modern environmental regulations.

ZOZEN 2 ton WNS gas fired boiler

ZOZEN Boiler’s 2-Ton Solutions: WNS and DZL Series

The WNS series is one of ZOZEN’s most widely adopted models in the boiler 2 ton category, designed to run on oil or natural gas. It features a horizontal, fire-tube, wet-back structure that ensures high durability and excellent heat transfer. The large-diameter corrugated furnace enhances the heat absorption area and provides enough steam storage volume for stable output.The WNS boiler achieves high thermal efficiency, typically around 98% under standard working conditions, due to its optimized furnace geometry and advanced heat recovery components such as economizers and condensers. Equipped with internationally recognized low-NOx burners, it ensures emissions can meet stringent regulations, including NOx levels below 30mg/Nm³ when required by government policy.In terms of operation, the WNS boiler 2 ton model integrates a fully automated control system. Operators can easily manage functions such as start-up, load adjustment, and water supply with minimal manual intervention. The high degree of automation not only reduces labor intensity but also minimizes human error, ensuring consistent performance over long-term use. For industries pursuing “coal-to-gas” transitions, the WNS series provides a clean, stable, and efficient replacement.

For enterprises that prioritize renewable energy utilization, ZOZEN offers the DZL single-drum biomass-fired steam boiler. As part of the boiler 2 ton lineup, this model is particularly suited to regions where agricultural residues or forestry waste can be used as fuel. It adopts a horizontal layout with a chain grate, enabling mechanical fuel feeding and efficient combustion of a variety of biomass types such as rice husks, wood chips, and corn stalks.The DZL boiler’s threaded smoke tubes and arched tube plate design significantly enhance heat transfer while preventing stress concentration, effectively resolving common maintenance issues like tube plate cracking.The thermal efficiency can reach 83% or more, depending on the fuel type, helping enterprises lower fuel costs while reducing carbon footprint.As an alternative to traditional coal-fired equipment, the DZL boiler 2 ton represents a balance between operational reliability and environmental sustainability. It is often adopted by agricultural processing industries and small manufacturing plants that have access to low-cost biomass resources, making it a cost-effective solution aligned with circular economy principles.

Case Study: Feed Industry Transition

In the pellet feed production process, steam plays a critical role during the conditioning stage. Proper conditioning ensures that feed particles soften adequately, improving digestibility for animals and directly influencing the nutritional quality of the final product. A well-managed steam system can therefore determine the competitiveness of a feed manufacturer in a growing market.

One feed company, with more than twenty years of development history, operates a production line capable of producing 150,000 tons of feed annually. As part of national environmental initiatives under the “coal-to-gas” policy, the company decided to replace its old coal-fired equipment with a cleaner and more efficient solution. In addition to energy savings, the company also emphasized that NOx emissions from the new boiler must remain below 30mg/Nm³ to comply with local environmental standards.

After analyzing the customer’s needs, ZOZEN recommended its WNS series boiler 2 ton model fueled by natural gas. The system was designed with a large corrugated furnace chamber to ensure full combustion and sufficient steam storage. With the integration of advanced low-NOx burners, the boiler was able to achieve the customer’s strict emission targets while still maintaining high operational efficiency.

ZOZEN also provided a complete boiler system design, covering not only the main unit but also auxiliary equipment such as economizers, burners, and automated control systems. This holistic approach guaranteed smooth installation, reliable operation, and long-term energy savings. The project was successfully inspected and approved by local environmental authorities, marking a significant upgrade in the company’s production process.

The plant’s management team later highlighted how the switch to the WNS series had reduced operating costs by lowering fuel consumption and cutting labor requirements thanks to the automation features. Beyond immediate compliance with regulations, the solution also positioned the company as an industry leader in sustainable feed production.

Technical and Service Advantages of ZOZEN Boiler

The boiler 2 ton is a versatile solution for medium-scale industrial applications, bridging the gap between small units and large central systems. Whether powered by oil, gas, or biomass, it provides steady steam to support industries ranging from feed processing to textiles and pharmaceuticals.

ZOZEN’s boiler 2 ton portfolio integrates technical sophistication with practical benefits for industrial users. The WNS oil/gas-fired boiler ensures ultra-clean operation and minimal environmental impact, while the DZL biomass-fired boiler offers renewable energy compatibility with solid fuel flexibility. Both designs emphasize stable performance, efficient heat transfer, and ease of operation.

Equally important is ZOZEN’s service commitment. Each project is supported by a professional technical team that provides tailored system design, on-site installation guidance, commissioning, and operator training. After delivery, ZOZEN continues to provide maintenance support and spare parts supply, ensuring that customers experience minimal downtime and optimal efficiency throughout the lifecycle of their boiler 2 ton systems.
