Low NOx Brochure

Product catalog summary
Overview: The document provides detailed specifications and features of the Quadflow Cyclopower 4VTLN Series high-pressure tubeless boilers, specifically the Cyclone Series. These boilers are designed for low NOx emissions and are available in both steam and hot water versions.
Specifications: The Cyclone Series boilers can achieve less than 30 PPM NOx at 3% O2 without induced flue gas recirculation. They are available in steam pressures ranging from 15 to 300 PSI and feature a four-pass design for efficient heat transfer.
Design Features: The boilers utilize a four-pass fin-flow system where gases are split and travel through individual serpentine fin passages. This design ensures even heat transfer, reducing metal stress and enhancing durability. The boilers also feature a turbulent flame for improved heat transfer and fuel-to-steam efficiency.
Performance and Efficiency: The Cyclone Series offers more steam storage capacity, allowing for quick recovery and response to load changes. The design reduces carryover of unevaporated water, resulting in drier steam and reduced system scaling.
Inspection and Maintenance: The boilers are designed with accessible waterside openings for easy inspection and cleaning. The strategic placement of handholes and top openings facilitates maintenance without obstructing access.
Installation and Accessories: The units are skid-mounted for easy handling and come factory-wired with a wiring schematic. Optional accessories include a compact boiler-mounted feedwater system and blowdown separators.
Customization and Options: The Cyclone Series can be customized to meet various installation requirements and specifications. The document outlines the primary, second, third, and fourth gas paths around the boiler shell.
Safety and Compliance: The boilers are built to ASME Section 1, High Pressure Boiler Code, and are CSD-1 approved. Electrical components are positioned to minimize water contact risks.
Technical Data: The document includes detailed technical data on firing rates, steam output, and dimensions for various models within the series.
Contact Information: The document provides contact details for Hurst Boiler, including phone numbers and email for further inquiries.

■ The waterside openings are located in the most effective positions. The lower handholes offer far better access for both cleanout and inspection. ■ Capacity to handle swing andspike loads quick recovery -quick response. ֢֠ The gases leaving the furnace are split four ways and travel through four individual serpentine fin passages to the stack outlet. ■ These more functional locations avoid the obstructing handhole tunnelsӔ used by our competitors. ■ Each quarter of the heattravels its own four-pass path (see illustration below). ■ The top opening offers a strategic view of the furnace crown...

■ Heat is forced down, with the fire whirling and spinning against its natural flow. This pattern enhances recirculation, mixing and heat transfer, driving more energy into the water for greater fuel-to-steam efficiency. ■ The furnace crown is water cooled, eliminating troublesome refractory breakdown inherent in units of inferior design. ■ PreCertified LOW NOx burner. ■ No fire tubes, water coils or in the fireӔ mud rings to burn out. ■ Burner can achieve less than 30PPM NOx at 3% O > 2 without inducedflue gas recirculation. > ■ Fire does not pass under the bottom mud ring, eliminating the blistering...
