Superheated Steam Boiler: ZOZEN SZS Gas-Fired Solutions for Industrial Applications

In modern industrial production, steam plays a decisive role as an essential source of energy. While saturated steam is widely used in processes such as sterilization, cooking, and low-temperature heating, certain industries require higher temperatures and greater efficiency, which cannot be achieved by saturated steam alone. This is where the superheated steam boiler becomes indispensable. By heating saturated steam above its saturation temperature without increasing pressure, superheated steam boilers deliver dry steam with higher enthalpy, ensuring that energy transfer is more efficient and heat loss during transportation is minimized.

With increasing environmental requirements and rising demand for energy efficiency, enterprises are shifting toward cleaner and more sustainable boiler solutions. ZOZEN Boiler (ZOZEN), a trusted manufacturer with more than 30 years of expertise in industrial boiler research and development, has designed advanced superheated steam boiler systems tailored to diverse industrial needs. Among them, the SZS gas-fired superheated steam boiler stands out with its combination of energy efficiency, operational safety, and technological innovation.

Specifications and Advantages of ZOZEN SZS Gas-Fired Superheated Steam Boiler

The SZS series gas-fired superheated steam boiler is one of ZOZEN’s flagship products, engineered with a focus on large capacity, stable operation, and energy-saving performance. Structurally, it adopts a double-drum, longitudinal D-type layout. This configuration not only optimizes the water circulation system but also improves the strength and reliability of the pressure components. The boiler body is enclosed with a full membrane water-cooled wall, which enhances the sealing performance of the furnace chamber, prevents smoke leakage, and increases the overall thermal efficiency.

The combustion system is central to the SZS boiler’s performance. It features a large furnace chamber design that supports the complete combustion of natural gas or other clean fuels. To achieve higher combustion efficiency, the system integrates advanced low-NOx burners, ensuring uniform flame distribution and stable operation. By precisely regulating fuel and air input, the boiler minimizes unburned components, reduces nitrogen oxide emissions, and complies with stringent environmental standards.

The thermal efficiency of the SZS superheated steam boiler can reach up to 98% when equipped with economizers and condensers. Heat recovery systems are designed to utilize residual flue gas energy, further lowering operational costs. The boiler’s large heating surface, combined with optimized flue gas flow paths, maximizes heat transfer while reducing the risk of fouling and ensuring sustained long-term performance.

Another key feature is the superheater system, which is specifically designed to deliver high-quality superheated steam. Arranged in the convection zone, the superheater tubes are exposed to high-temperature flue gases, allowing the boiler to reliably produce superheated steam with stable temperature control. This makes the SZS boiler an ideal choice for industries requiring continuous and precise high-temperature steam supply.

In terms of operation, automation and intelligent control are integral to the SZS boiler. The system provides real-time monitoring of critical parameters such as steam pressure, superheated steam temperature, and feedwater level. Advanced safety devices, including automatic water level adjustment, pressure interlocks, and flame detectors, ensure that the boiler maintains safe and reliable operation under various load conditions.

Case Study: 40-Ton Gas-Fired Superheated Steam Boiler Project

A new energy company specializing in thermal energy supply recently faced the challenge of upgrading its steam generation system to meet rising production demands. To secure a reliable solution, the company launched a public tender for a 40-ton gas-fired boiler project. ZOZEN Boiler, with its established reputation for product quality and extensive industry experience, successfully won the bid and became the trusted supplier for the project.

The solution provided was an SZS series gas-fired superheated steam boiler, specifically designed to deliver large volumes of high-temperature steam with exceptional energy efficiency. The D-type double-drum design and fully enclosed membrane water-cooled wall structure ensured excellent sealing and heat transfer efficiency. The large furnace chamber allowed for complete fuel combustion, while the system’s compatibility with ultra-low-NOx burners further enhanced environmental performance by minimizing emissions.

For this project, the SZS boiler was equipped with energy-saving auxiliaries, including economizers, which significantly improved the utilization of residual heat. Performance testing showed that the boiler’s thermal efficiency reached as high as 98%. This directly reduced the energy consumption per unit of steam produced, translating into substantial operational savings for the client.

Beyond energy efficiency, the stability of superheated steam output was critical to the success of the project. In applications where steam quality directly impacts downstream processes, such as turbine drives or high-temperature heating, fluctuations can lead to significant losses. The ZOZEN SZS boiler’s advanced control system maintained precise regulation of steam temperature and pressure, ensuring consistent supply throughout production cycles.

The successful commissioning of the 40-ton superheated steam boiler project not only satisfied the client’s immediate production requirements but also laid a solid foundation for future cooperation between ZOZEN Boiler and the energy company. The project highlighted ZOZEN’s ability to integrate engineering expertise, advanced design, and customer-oriented service into a comprehensive solution.
