Engine Exhaust Power Generation

HT1300MAGM (HT704C-MAGM)

INTRODUCTION

Shannon Thermal Blankets are a CAD designed, CNC produced, high quality pre-engineered insulation system designed to save energy, retain radiant heat, minimize insulation maintenance and improve the surrounding work environment. Shannon is weather resistant and chemical resistant. Shannon is flexible and easy to install, remove and reinstall allowing quick access and easy equipment serviceability. The key benefit is re-usability.

Common Applications and Markets
Gas Turbines, Catalytic Converters, Turbine Exhaust Duct, Engine Exhaust Manifolds, Reducer Cones, Mufflers, Expansion Joints, Piping, Fittings, By-Pass Piping and Turbo Charger Casings. Markets: Private/Public Utilities, Oil & Gas Industry, CHP, Marine Industry.

Service Temperature
Engine & Turbine Systems – This design is to act as a Thermal Barrier with a maximum service temperature of 1300˚F (704˚C).

Product Components
The Outer Jacketing consists of a layer of Stainless Steel Type 304 Knitted Wire Mesh (.011” Dia. @ 16ft²/LB@0.28 mm Dia. @ 3.3 m²/kg) and 9.5oz/yd² (323g/m²) Aluminized Composite Laminate Fiberglass Cloth. The inner jacketing consists of Stainless Steel Knitted Wire Mesh (same as above). The Insulation Material is a combination layer of 8lb/ft3 (128 kg/m³) Ceramic Needled Fiber Mat & a layer of 11 lb/ft3 (176.2kg/m3 ) Fiberglass Needled Mat-Type E Fiber. The insulation is encapsulated by the inner and outer jacketing, then stapled together, producing a Self Contained Blanket System. The Blanket System includes an Integral Fastener for install.

* The above referenced Cold Face Surface Temperatures should be used as guidelines for blanket insulation thickness design.
* The Cold Face Surface Temperature of the blanket should approach surrounding ambient temperature conditions.
* The economic thickness of the blanket should consider blanket cost, thermal performance and blanket design constraints.
* Heat loss calculations are based on a 21.1˚ C (70˚ F) ambient temperature using a flat surface condition.
