Firebox Series 45

Product catalog summary

Overview: The Hurst Performance Series Boilers are low-pressure boilers with capacities ranging from 8.5 to 813 Boiler Horsepower (BHP) and output from 285 to 27,215 MBTU/HR. These boilers are designed for both steam and hot water applications, with steam pressure up to 15 PSI and hot water pressure options of 30, 60, or 100 PSI.

Design and Construction: The boilers feature a 3-pass efficiency design and all-steel firebox construction. They are compact and easy to install, with factory-packaged units that include operating controls, relief valves, burners, and fuel trains. The boilers are constructed and stamped according to ASME Code Section IV and are registered with the National Board of Boiler Inspectors.

Fuel Flexibility: The burner systems are flexible, allowing for the use of natural gas, LP gas, #2 oil, heavy oil, or combinations thereof. The boilers are equipped with UL-listed forced draft burners and controls.

Efficiency and Maintenance: The boilers are designed for high efficiency with features such as a large furnace volume for optimal combustion efficiency, low heat release, and factory insulation with 2-inch mineral wool to reduce radiant heat loss. They are also designed for easy maintenance with ample waterside clean-out openings and easy access to fireside surfaces.

Safety and Controls: Standard steam trim includes operating and high limit pressure controls, modulating pressure control, and safety relief valves per ASME Code. Hot water models include similar controls for temperature. Both models feature low water cut-off controls with manual reset and combination pressure and temperature gauges.

Specifications: The document provides detailed specifications for various models, including dimensions, firing rates, heating surfaces, and water volumes. It also notes that connections up to 4 inches are NPT thread, while those 6 inches and above are 150# ANSI flange.

Additional Features: The boilers have a unified refractory base floor, steel skids, lifting eyes, and are factory jacketed and painted. They are fully automatic and factory test-fired, ensuring reliability and performance.
