Introduction

> SZS Series Oil Gas Fired Boiler
Water Tube Boiler | Double Drums Water Membrane Wall Boiler
※ SZS gas & oil water tube boiler is arranged as drum longitudinal type “D” shape, it’s quickly assembled boiler with water tube, has the characteristics of high steam quality, sufficient output, high thermal efficiency, etc.
※ The structure of furnace water cooling wall and convection gas pass is membrane wall, have good sealability, and effectively reduce refractory brick quantity and maintenance workload.
※ The layout of economizer at boiler tail could effectively reduces exhaust gas temperature and improve boiler thermal efficiency.
※ This series gas fired water tube boiler is delivered as whole when leave factory, convenient for transportation, and has a short install period.
> Advantages of SZS Series Boiler
1. High Efficiency: SZS boilers are designed for high efficiency and can achieve a high level of thermal efficiency, ensuring better fuel utilization and lower operating costs.
2. Large Heating Surface Area: These boilers typically have a larger heating surface area compared to other types, which enhances heat transfer and efficiency.
3. Compact Design: Despite their high efficiency and power, SZS boilers are often designed to be compact, saving space and making installation more manageable.
4. Low Emissions: They are designed to meet stringent emission standards, reducing environmental impact by minimizing pollutants released into the atmosphere.
5. Reliability: SZS boilers are known for their reliability and durability, offering consistent performance over extended periods with proper maintenance.
6. Easy Maintenance: While regular maintenance is necessary for any boiler system, SZS boilers often have features that facilitate easier access for maintenance and servicing.
