Performance Features

• High Efficiency & Compact Design: The combustion chamber is eccentrically placed within the vertical boiler shell, providing ample combustion space and heating surface for complete and efficient combustion. The second pass consists of threaded smoke tubes, which significantly enhance heat transfer efficiency. The combustion system is located at the top of the boiler, making the entire structure compact and saving considerable space in the boiler room.

• Energy-Saving & Environmentally Friendly: The boiler boasts high thermal efficiency and features such as fully automated operation, over-temperature standby, and frost protection during cold winter nights. The system automatically adjusts the heating output according to the ambient temperature, optimizing energy savings. Complete combustion of fuel reduces smoke and harmful emissions such as NOx, ensuring compliance with strict environmental standards.

• Safety & Reliability: The boiler is designed to be safe and reliable, with a long service life.

Structural Principle

• The CLHS series hot water boiler adopts a two-pass smoke tube structure with an eccentrically placed vertical combustion chamber. The second pass smoke tubes are threaded to maximize heat transfer and lower exhaust gas temperature, enabling efficient boiler operation.
