Definition and Advantages of Low Pressure Boilers
Low pressure boilers refer to boilers that operate at a pressure lower than 1.25 MPa. These boilers are widely used in various industrial settings due to their favorable safety profile and cost-effectiveness. Compared to high pressure boilers, low pressure boilers are subject to less stringent regulatory requirements and are generally easier to operate and maintain. One of the main advantages of low pressure boilers is their enhanced safety, as lower operating pressure reduces the risk of system failures and explosions. In addition, these boilers typically have simpler mechanical structures, which contributes to lower maintenance costs and longer service life. Furthermore, modern low pressure boilers are designed with energy efficiency in mind, helping companies to reduce fuel consumption and operating costs. Their compact design and flexible installation options make them a practical choice for small to medium-sized facilities, where space and budget are often limited. Overall, low pressure boilers provide a reliable and economical solution for industries that require consistent heat or steam supply without the complexity of high-pressure systems.
Industrial Applications of Low Pressure Boilers
Low pressure boilers are suitable for a wide range of industrial applications where moderate steam or hot water is required. In the food and beverage industry, these boilers are commonly used for processes such as pasteurization, sterilization, and cooking, where precise temperature control is essential. In textile manufacturing, low pressure boilers support dyeing, drying, and ironing operations by providing stable heat. The pharmaceutical industry also relies on these boilers for sterilization and the production of medicines, where clean and consistent steam is crucial. Furthermore, chemical production facilities use low pressure boilers for heating reactors and distillation columns, as these processes often require stable temperatures but not high steam pressure. Because of their versatility, safety, and efficiency, low pressure boilers have become a preferred choice for many organizations across different sectors.
Parameters and Advantages of ZOZEN Boiler’s WNS, SZS, SZL, and DZL Low Pressure Boilers
ZOZEN Boiler offers a comprehensive lineup of low pressure boilers, including the WNS, SZS, SZL, and DZL series, each engineered to meet specific industrial needs with high efficiency and environmentally friendly performance.
The WNS series is a horizontal, internal combustion, gas or oil-fired steam boiler. Designed for pressures below 1.25 MPa, it features a full wet back design, a corrugated furnace, and threaded smoke tubes, which significantly improve heat transfer. With condensing technology, the WNS series achieves thermal efficiency above 98% and ultra-low NOx emissions under 30 mg/Nm³.
The SZS series is a D-type water tube boiler that is ideal for larger-scale industrial applications. It supports low-pressure operation and offers a high steam capacity range. Its double-drum design ensures excellent water circulation and thermal stability, while also meeting strict emission standards with advanced low-NOx burners.
The SZL series is a chain grate boiler suitable for biomass and coal fuels. Its high-efficiency heat exchange system and optimized combustion design make it a reliable low pressure boiler for industries with solid fuel preferences.
The DZL series is a single-drum chain grate boiler designed for low-pressure operation with coal or biomass fuel. It features a high heat transfer coefficient, fast steam production, and a compact structure, making it suitable for smaller industrial plants aiming for efficient and economical steam generation.
All four series of ZOZEN low pressure boilers prioritize safety, environmental compliance, and user-friendly automation. With intelligent control systems, real-time monitoring, and modular designs, these boilers support stable operation and long service life while helping industries reduce their carbon footprint and fuel expenditures.
Case Study: ZOZEN Boiler Supporting Baijiu Production
A prominent baijiu distillery recently selected a 2-ton WNS series gas-fired steam boiler from ZOZEN Boiler to support its new production project with an annual output of 500,000 kilograms of baijiu. In the baijiu distillation process, the quality and stability of steam directly impact the aroma, clarity, and overall quality of the liquor. The distillation process also requires precise thermal control to ensure consistent production standards and optimize energy usage.
ZOZEN Boiler’s WNS series low pressure boiler was chosen for its advanced features and proven performance in the food and beverage industry. The boiler is equipped with high-efficiency condensing technology that recovers heat from exhaust gases, significantly improving thermal efficiency and reducing operational costs. This not only aligns with the distillery’s goals of energy conservation but also helps lower greenhouse gas emissions.
Additionally, the boiler provides stable and continuous steam output, which is essential in maintaining uniform distillation temperature. This consistency ensures that each batch of baijiu meets the same high-quality standards. ZOZEN’s low pressure boiler also features a fully automated control system that allows for simple operation and precise adjustment, ensuring both safety and ease of use for on-site personnel.
Through this project, ZOZEN Boiler demonstrated its ability to tailor solutions to industry-specific requirements. The successful application of the WNS series in the distillery highlights ZOZEN’s strengths in combining advanced technology with practical, user-friendly design. It also reinforces ZOZEN’s reputation as a preferred partner in the food and beverage sector for efficient and environmentally conscious steam solutions.
