LPG Boilers for Industrial Steam: ZOZEN Boiler Solutions

In modern industrial production, a stable and efficient steam supply is essential for ensuring consistent product quality, process efficiency, and energy management. Among the diverse types of steam generation systems, LPG boilers have become an important choice for industries requiring clean combustion, precise temperature control, and flexible fuel utilization. Using liquefied petroleum gas as the fuel source, LPG boilers offer rapid response, low emissions, and ease of operation, making them suitable for applications such as food processing, chemical production, textile manufacturing, and pharmaceutical operations.

The advantages of LPG boilers include fast startup, high combustion efficiency, and reduced pollution compared to conventional coal-fired or heavy oil-fired boilers. These systems are able to deliver continuous and controllable steam output while operating under relatively low environmental impact. In addition, LPG as a fuel is widely available and convenient to transport, further increasing the appeal of LPG boilers for industrial facilities that prioritize operational efficiency and sustainability.

With extensive experience in industrial boiler design and manufacturing, ZOZEN Boiler has positioned itself as a reliable provider of LPG boilers for enterprises worldwide. ZOZEN focuses on creating steam solutions that integrate advanced combustion technology, robust heat transfer design, and durable construction. By tailoring boiler systems to match production needs, ZOZEN LPG boilers provide both stable operation and efficient energy utilization.

WNS and SZS LPG Boilers from ZOZEN: Fuel, Design, and Technical Advantages

To address the diverse needs of industrial users, ZOZEN provides two main series of LPG boilers: the WNS fuel and gas-fired steam boiler and the SZS fuel and gas-fired steam boiler. Both series are designed for high-efficiency steam generation, stable operation, and reliable safety performance while offering flexibility in fuel selection.

The WNS series LPG boiler is a horizontal, three-pass, wet-back shell-type boiler designed to deliver stable steam output with high thermal efficiency. Its combustion chamber features a large-diameter corrugated furnace, which provides sufficient space for complete fuel combustion and ensures uniform heat distribution. Threaded smoke tubes enhance heat transfer and increase the overall thermal efficiency of the boiler. With the addition of economizers and optimized flue gas paths, a WNS series LPG boiler can achieve a thermal efficiency of up to 98%, depending on site conditions and fuel quality. The wet-back design not only improves furnace durability but also simplifies maintenance by providing easy access to critical components.

The SZS series LPG boiler is a vertical, single-drum, three-pass structure designed for medium to large-scale industrial applications requiring consistent steam supply. The SZS boiler incorporates advanced water-cooled walls in the furnace and a multi-pass flue gas path to enhance heat absorption. This series is compatible with LPG, natural gas, and other clean gaseous fuels. With efficient burners and precise air–fuel ratio control, the SZS LPG boiler provides stable steam output at variable loads while maintaining low emissions. The structural design of the SZS series supports rapid startup, smooth temperature control, and long-term operational reliability, making it suitable for continuous production environments.

Both WNS and SZS LPG boilers are equipped with multiple safety features, including water level monitoring, pressure protection, and combustion control systems. These measures ensure safe operation and protect against overpressure or overheating, which is essential for industrial applications requiring uninterrupted steam supply. ZOZEN’s engineering approach ensures that each boiler is tailored to meet specific industrial production requirements, balancing efficiency, fuel cost, and operational reliability.

Case Study: LPG Boilers for a Meat Processing Plant in Venezuela

Recently, ZOZEN Boiler successfully supplied a meat processing factory in Venezuela with two WNS series LPG steam boilers. One unit has a capacity of 5 tons per hour, while the other is a 10-ton-per-hour boiler. These boilers were deployed on two separate production lines, providing continuous and efficient steam supply essential for the plant’s operations.

Meat processing involves multiple stages such as raw material handling, sterilization, cooking, and drying, all of which require stable steam supply. Consistent steam not only supports higher product quality but also ensures food hygiene and safety standards are maintained. The performance of the LPG boilers directly impacts production efficiency and product consistency in this context.

The WNS series boilers installed at the meat processing facility use a three-pass fire-tube design with a corrugated furnace and threaded smoke tubes. This configuration greatly improves heat transfer efficiency, allowing the boilers to achieve thermal efficiency exceeding 100% under optimal operational conditions. For the meat processing plant, this design translates into lower fuel consumption, reduced operating costs, and minimized carbon emissions, offering both economic and environmental benefits.

Furthermore, both WNS LPG boilers supplied to the facility are ASME-certified, demonstrating compliance with international safety and quality standards. ASME certification is recognized globally as a benchmark for mechanical design, construction, and operational reliability, ensuring that the boilers can meet the stringent requirements of international markets and industrial users.

The installation and commissioning were completed with close coordination between ZOZEN engineers, the plant’s technical team, and the local agents. The collaboration ensured the boilers delivered stable steam from the outset, supporting uninterrupted production across both meat processing lines.
