Product catalog summary
Specifications:
The Cleaver-Brooks CBL model is a 3- or 4-pass wetback firetube boiler designed for hot water or low and high-pressure steam applications. It ranges from 900 to 1,600 horsepower and offers fuel flexibility, capable of firing natural gas, No. 2 oil, No. 6 oil, or a combination of these fuels. The boiler is designed to meet high design pressures from 150 psig to 250 psig and adheres to industry standards such as the ASME Code and NEC.
Design and Efficiency:
The CBL model boasts a compact design that conserves floor space, making it ideal for facilities with limited space. It achieves high fuel-to-steam/water efficiencies exceeding 80% through precise combustion and heat transfer design. The large furnace area allows over 35% of energy absorption, contributing to its compactness and efficiency.
Emissions and Environmental Impact:
The boiler is designed to minimize emissions, particularly nitrogen oxides (NOx), through advanced burner design and proper furnace sizing. It can be equipped with the ProFire LN burner, achieving NOx emissions as low as 100 or 30 PPM when burning natural gas.
Maintenance and Safety:
The CBL model offers easy maintenance with features like a hinged forced draft burner and swing-out burner assembly. It includes safety features such as the CB7B0E Flame Safeguard Control and Level Master low-water cutoff. The boiler is equipped with a modulating feedwater valve and auxiliary low water control for enhanced safety.
Optional Upgrades:
The boiler can be upgraded with options such as seismic design, blowdown valves, and advanced burner management controls like the Hawk system. It also offers low NOx gun burners with and without flue gas recirculation (FGR) for further emission reductions.
Conclusion:
Cleaver-Brooks has a long-standing reputation for innovation in boiler solutions, focusing on energy efficiency and environmental friendliness. The CBL model exemplifies this commitment by integrating advanced technology and design to deliver a reliable and efficient boiler system.
