Introduction to ZOZEN Boiler's 30-ton+ Gas-Fired Steam Boiler Application Cases

Focusing on "application cases of 30-ton+ gas-fired steam boilers," this article selects three different industry scenarios to showcase the technical features and application results of ZOZEN Boiler's SZS series gas-fired steam boilers. Through these cases, the reliability, energy efficiency, and environmental performance of ZOZEN boilers in large-scale heating and industrial processes are clearly demonstrated.

1. Zhejiang Hengxi Energy Taizhou Centralized Heating Project
This project adopts a centralized energy model to replace decentralized boilers, utilizing multiple ZOZEN SZS series gas-fired steam boilers with a total capacity of 200 tons, making it a typical application case of 30-ton+ gas-fired steam boilers. The project is expected to supply 403,300 tons of steam annually, with an annual natural gas consumption of approximately 37.3294 million cubic meters, significantly reducing standard coal consumption and supporting regional energy-saving and emission reduction goals. This case highlights the peak-shaving capability, rapid start-stop, and stable steam supply of SZS units in multi-boiler parallel systems.

2. Shandong Huarui Investment Holding Co., Ltd. Project
The enterprise configured two 35-ton SZS series gas-fired steam boilers at once, forming a stable application case of 30-ton+ gas-fired steam boilers. ZOZEN's SZS boilers feature a double-drum, vertical, D-type layout, with membrane water-cooled walls effectively isolating the furnace from convection heating surfaces, improving heat transfer efficiency. The large furnace design, combined with an economizer and condensing recovery system, reduces exhaust gas temperature. IoT remote control and expert management systems enable automation and reduced manpower operation, while low-nitrogen combustion technology ensures NOx emissions ≤30 mg/Nm³. This case emphasizes ZOZEN Boiler's comprehensive capabilities in high efficiency, low emissions, and intelligent operation.

3. Xinjiang Hongguoguo Tomato Products Co., Ltd.
Tomato paste production requires extremely high steam stability during the 45–55-day concentrated operation period. ZOZEN Boiler supplied an SZS series 35-ton gas-fired steam water tube boiler, ensuring 24-hour continuous full-load operation to meet the steam quality requirements for key processes such as evaporation and concentration. This case not only demonstrates the continuous and stable steam supply capability of SZS units in food processing but also highlights the value of ZOZEN's comprehensive after-sales service in ensuring production continuity.

Summary
Based on the above cases, the core advantages of ZOZEN's SZS series gas-fired steam boilers include: capacity coverage of 2–110 t/h, pressure range of 1.25–5.3 MPa, saturation temperature of 193–270°C, and compatibility with various fuels (natural gas, coke oven gas, biogas, and oils); D-type layout and full membrane water-cooled wall structure ensure uniform heat transfer and easy maintenance; low-nitrogen combustion and condensing technology improve efficiency and meet environmental requirements; IoT and remote operation enhance system visibility and response efficiency. Urban heating networks, chemical, and food enterprises can refer to these cases and choose ZOZEN's SZS series to build an efficient, stable, and clean steam supply system.
