Steam Boiler Overview – Fulton VSRT 10 TO VSRT 50 The Fulton Vertical Spiral Rib Tubeless (VSRT) Steam Boiler is a new technology product manufactured in the USA to ASME standards and comes complete with formal design registration to the applicable Australian Standard AS1228 for Pressure Equipment – Boilers. It has also been designed to ensure full compliance in Australia to AS2593 for Unattended operation, and the product is supported with a 5-year warranty on pressure parts. The patent pending spiral rib heat exchanger achieves industry leading heat transfer rates using a unique spiral design, providing a long heat transfer path which is optimized to achieve maximum heat recovery in a compact space. The VSRT features a fully water backed pressure vessel, wrapped with high density insulation, resulting in low jacket temperatures that significantly reduce latent heat losses. The VSRT range is also equipped with highly sophisticated forced draft burner and combustion management systems that have been developed by Fulton for each boiler capacity, as an integral part of the boiler, being accurately matched to the heat output and combustion chamber characteristics. Extensive use has been made of “Pure Optimized” engineering principles that result in industry leading boiler performance achieving thermal efficiencies of up to 86%, 6:1 turn down ratio, and NOx emissions of less than 20 ppm in standard configuration.

Steam Boiler Design – Fulton VSRT 10 TO VSRT 50 The combustion gases transition downward from the combustion chamber into the spiral heat exchanger and the Flue gases spiral upward through the patent-pending heat exchanger. The VSRT extensively utilises self-compensating stress relieving architecture. The spiral rib heat exchanger is fully immersed in water to optimize heat transfer, creating not only a longer-lasting boiler, but can transfer the most amount of heat in the most compact space.

Combustion Air Filtering The Fulton cyclonic air filter effectively cleans and filters the combustion air into the burner, removing damaging particles and dust. The benefit of this filter significantly improves longevity of combustion components, and maintains efficiencies. Suitable for a Wide Range of Applications

Summary of FULTON VSRT Benefits

In summary, the benefits of the Fulton VSRT Ultra-efficient Unattended Fire Tube Steam Boiler are: o Industry leading efficiencies of up to 86% o Low Nitrogen Oxide (NOx) emissions, standard at better than 20 ppm o Integrally designed burner for up to 6:1 turndown ratio, complete with LMV linkageless

control o Variable Speed Drive (VSD) burner fan, significantly improving boiler efficiency, reducing

energy costs, and increasing component operational life o All wrapped insulation is used with no Refractory, reducing latent heat escape and

maintenance o Boiler jacketed in stainless steel reducing significantly the effects of corrosion o The spiral rib design of the pressure vessel significantly reduces thermal stress and

corrosion o Highest steam quality available at 99.75% o Fully wetted pressure vessel with very generous water volume for better reaction to load

swings o User friendly control panel with HMI for ease of operation o Smaller footprints ensuring better installation outcomes o Manufactured in USA, design approved and fully compliant to all Australian Standards o Less extensive maintenance program – The VSRT boiler range requires three (3) x 3-

monthly and one (1) x annual service per year for Unattended boilers covered by AS2593. This will reduce the time the boiler is off line and promote the use of multiple boilers for some applications

o Standard 5-year warranty on pressure vessel.

Summary of FULTON VSRT Inclusions

As standard supply the VSRT Fulton steam boiler is inclusive of the following: o Fully insulated and jacketed pressure vessel o Natural Gas or LPG fully modulating burner and gas train complete with combustion

management system o VSD burner fan and control management system o Pre-wired and tested control panel with HMI o Cyclonic air filter o Exhaust stack takeoff spigot o Main Steam valve o Safety valve o Manual Blowdown valve o 2 x High pressure water level indicators o Water control system including pump control and low-level safety cutout devices o Steam control system including pressure and modulation controls o All control and interlocks required by AS2593
