While we were at the AHR Expo last month, we were pleased to have our Central Florida representative showcase us during the Live Fire Boiler Room tour at the local hotels in Orlando. I’d like to extend a special thank you to Clark Welding & Fabricating, our representatives from Las Vegas, and Engineered Energy Equipment, our representative here in Orlando, for their support in making this #boiler tour video a success!
This featured boiler room includes the Hurst Boiler Series 500, a four-pass wetback design with a Hurst internal stack economizer. It also features a Webster Combustion Burner, controlled by the Autoflame Engineering Limited burner control system.
The Hurst 500 Series four-pass wetback Scotch marine #boiler is an ideal choice for both commercial and industrial applications, particularly when designing mechanical systems that incorporate the latest #hvacr technologies. This boiler offers fuel efficiencies that exceed those of most other four-pass designs. Notably, it eliminates the need for a large refractory rear door, giving technicians easy access to all tubes. The boiler front doors can be opened without needing to remove any burner components or controls.
Key features include:
Factory Assembled, Prewired, and Tested
No Field Assembly Required
UL Listed Boiler/Burner Packages
Fully Assembled, Pre-piped, Pre-wired, Pressure-Tested Gas Trains
Compliance with ASME, UL, CSD-1, and ASHRAE Standards
High Efficiency and Low Stack Temperatures
Additionally, the Hurst internal stack economizer is a factory-optional device designed to improve the operating efficiency of the boiler, ultimately lowering operational costs over the boiler's lifespan.
Boilers operate by heating water to produce steam, which is then used for heating, processing, or power generation. Although a boiler is generally efficient, heat loss can occur when flue gases from combustion are vented. These gases are often very hot, and when they are simply expelled through the exhaust stack, this represents lost heat.
The Hurst stack economizer helps recover this lost heat, acting as a waste heat recovery device. Instead of letting this heat go unused, it’s captured and used to preheat the boiler’s makeup water. This serves as an integrated feedwater heater, ensuring that the makeup water is preheated to near-boiling temperatures, reducing the energy required to bring it up to steam.
