Overview of Hurst Hybrid Series Coal-Fired Boiler System

The Hurst Hybrid Series represents an advanced boiler design integrating a watertube furnace with a multi-pass firetube vessel. This hybrid configuration enhances fuel efficiency beyond conventional solid fuel boilers by maximizing radiant heat utilization within the water-cooled furnace and maintaining low stack temperatures through balanced heat exchange.

Key Features and Benefits:

• Fuel Flexibility: Capable of efficiently firing dry wood, wet wood, coal, and various waste fuels.
• Auxiliary Fuel Capability: The watertube furnace design supports auxiliary fuels such as gas, fuel oil, and waste oil, enhancing operational versatility.
• Improved Efficiency: The combination of watertube furnace and multi-pass firetube vessel results in superior thermal efficiency and reduced emissions.

System Components and Flow:

• Coal Storage and Handling: Coal is stored in designated bunkers and hoppers, with metering rod valves controlling feed rates.
• Coal Transfer: Bucket elevators and conveyors transport coal from storage to the boiler furnace.
• Combustion and Heat Recovery: The hybrid boiler combusts the fuel, transferring heat through the watertube furnace and firetube sections.
• Emission Control: Ash and particulate matter are collected via ash screws, ash collectors, bag house collectors, and optionally precipitators or scrubbers to meet environmental standards.
• Air Flow Management: Induced draft fans regulate combustion air and flue gas flow to optimize combustion efficiency.

Environmental and Operational Considerations:

• Optional precipitators or scrubbers can be integrated for enhanced emission control depending on regulatory requirements.
• Common ash collection systems consolidate ash handling for ease of maintenance and disposal.
