Reliable and Efficient Boiler for Hospital Applications — ZOZEN Boiler

In modern healthcare systems, a reliable boiler for hospital use is one of the most essential pieces of infrastructure. Hospitals depend heavily on stable and high-quality steam or hot water supply to ensure smooth daily operations. Steam is used for sterilizing medical instruments, disinfecting linens, preparing food, and heating wards. Given these diverse applications, the performance of a boiler for hospital directly impacts the safety, hygiene, and comfort levels within medical facilities.

Boilers used in hospitals are typically divided into two main categories — steam boilers and hot water boilers. Steam boilers are primarily employed for sterilization, laundry, and humidification systems, while hot water boilers provide space heating and domestic water supply. Depending on the hospital size, design capacity, and energy source, the boiler for hospital can range from small units for clinics to large multi-ton boilers serving full-scale medical complexes.

ZOZEN Boiler, a leading industrial boiler manufacturer with over three decades of experience, has developed a range of high-performance boilers tailored for medical institutions. ZOZEN’s product lines cover various steam and hot water systems designed for reliability, energy efficiency, and environmental compliance — all critical factors for healthcare operations.

Advanced Boiler Solutions for Hospitals by ZOZEN

The WNS series represents one of ZOZEN’s most popular designs for hospital applications. This horizontal, internal combustion, three-pass wet-back boiler is ideal for healthcare facilities requiring a stable source of high-quality steam for sterilization and laundry services.The WNS boiler for hospital features a large-diameter corrugated furnace that improves combustion efficiency and heat transfer. The full wet-back structure minimizes heat loss and enhances durability by reducing stress concentration in the rear tube plate. Advanced imported burners are integrated for optimal air-fuel ratio control, ensuring full combustion with minimal pollutant emissions.

When equipped with a high-efficiency condenser, the overall thermal efficiency can exceed 98%. This means hospitals benefit from significant fuel savings and lower carbon footprints. The system also incorporates intelligent control functions — allowing automatic operation, remote monitoring, and precise load adjustment according to real-time steam demand.The low nitrogen oxide (NOx) burner technology, paired with the large combustion chamber, enables emissions as low as 30 mg/Nm³, fully meeting national and local environmental standards. This clean and efficient boiler for hospital is an excellent fit for urban medical centers that prioritize both performance and sustainability.

For areas where gas resources are limited, ZOZEN’s SZL series coal-fired steam boiler remains a reliable option. It adopts a double-drum, vertically arranged chain-grate structure with natural circulation, suitable for burning bituminous, anthracite, and blended coal. The boiler body is surrounded by densely arranged membrane water walls to enhance heat absorption and ensure a well-sealed furnace structure.The SZL boiler for hospital offers strong adaptability to various coal types while maintaining a steady steam output. The multi-duct air supply design allows accurate control of combustion, improving fuel utilization and reducing unburned carbon. Its large furnace volume and sufficient radiation heating area ensure complete fuel burning, maintaining a thermal efficiency above 81%.

While steam boilers are vital for sterilization, many hospitals also require an efficient hot water system for central heating, bathing, and domestic use. The SZS series gas/oil-fired hot water boiler is designed precisely for such applications.This boiler for hospital features a double-drum, D-type layout with a fully sealed membrane wall structure that ensures excellent heat transfer and tightness. The furnace volume is large, providing sufficient space for complete fuel combustion, while the convection heating surface maximizes heat recovery from the flue gas.Equipped with a high-performance burner and advanced automatic control system, the SZS boiler for hospital delivers stable output, quick response, and precise temperature regulation. The use of high-quality insulation materials minimizes heat loss, improving overall system efficiency.

WNS Series Boiler Serving Nanyang Second People’s Hospital

Large hospitals often operate around the clock, requiring uninterrupted steam for sterilization, disinfection, and laundry services.In response to the national policy promoting clean energy transformation, the Henan Provincial Government has been actively advancing the “coal-to-gas” initiative. As part of this program, the hospital decided to replace its outdated coal-fired system with a new boiler for hospital that could meet modern environmental and operational standards.

After comparing multiple manufacturers, the hospital’s project team was impressed by ZOZEN’s modern production line, strict quality management system, and strong service capability. Eventually, they chose a WNS10-1.25-Q gas-fired steam boiler — a 10-ton/hour unit from ZOZEN’s WNS series.

This boiler for hospital is equipped with an internationally certified low-NOx burner and features a large-diameter furnace to ensure complete combustion. The NOx emissions are controlled below 30 mg/Nm³, meeting the region’s stringent emission requirements. The boiler’s generous steam space and heat transfer surface guarantee stable steam output and consistent pressure, crucial for sterilization and laundry operations.

Since installation, the WNS boiler has operated reliably, providing a constant supply of clean steam to the hospital’s autoclaves, washing machines, and dryers. The system’s intelligent control allows operators to easily monitor performance, manage load fluctuations, and maintain energy efficiency. ZOZEN’s on-site engineers provided installation supervision, commissioning support, and training for hospital staff, ensuring seamless integration into daily operations.

The project not only improved the hospital’s steam quality and energy efficiency but also demonstrated how advanced gas-fired boilers can support sustainable development in the healthcare sector.
