Engine Exhaust Power Generation

HT1500MSSiM (HT815C-MSSiM)

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. 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 1500˚F (815˚C).

Product Components
The Outer Jacketing consists of a layer of Stainless Steel Type 304 Knitted Wire Mesh 0.11” Dia. @ 16ft²/lb (0.28 mm Dia. @ 3.3 m²/kg) and 577g/m² (17.0oz/yd²) Silicone Impregnated Fiberglass Cloth. The inner jacket consists of a layer of 610g/m² (18.0oz/ yd²) Ceramic Silica Cloth with an outer layer of Stainless Steel Type 304 Knitted Wire Mesh (0.28 mm Dia. @ 3.3 m²/kg). The Insulation Material is a 128 kg/m³ (8lb/ft3) Ceramic Needled Fiber Mat. The Mat is encapsulated by the Stainless Mesh, Silicone Fiberglass Cloth, Stainless Sheet Foil and Stainless Mesh, then stapled together, producing a Self Contained System. The Blanket includes Integral Fasteners.

* 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.
