Thermal Engine Exhaust

MT850AGM (MT455C-AGM)

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 Thermal Blankets are weather and chemical resistant. Shannon Thermal Blankets are flexible, easy to install, remove and reinstall allowing quick and easy serviceability. The key benefit is re-usability.

Common Applications and Markets
Shannon Thermal Blanket Applications include: Engine Manifolds, Piping, Expansion Joints, Fittings, Flanges, Couplings. Shannon Thermal Blanket Markets; OEM Engine Manufacturing, CHP, Gen Sets, Gas Turbine & Reciprocating Engine Exhaust. Blankets are Self-Contained.

Service Temperature/Condition
Engine Exhaust Systems up to 850F (455˚C). This design is to act as a Thermal Barrier with a maximum service temperature of 850˚F (455˚C).

Blanket Components
The Outer Jacket is a 9.5oz/yd² (323g/m²) Aluminized Composite Laminate Fiberglass Cloth. The Inner Jacket consists of a layer of Stainless Steel Knitted Wire Mesh (.011” Dia. @ 16SF/LB – 0.28 mm Dia. @ 3.3 m²/KG). The Insulation Core Material is an 11lb/ft³ (176.2 kg/m³ ) Fiberglass Needled Mat- Type E Fiber. The Fiberglass Mat is encapsulated by the outer Aluminized Composite Laminate Fiberglass Cloth, inner Plain Fiberglass Cloth and Stainless Steel Knitted Wire Mesh, sewn together, producing a Self-Contained Blanket System. The Shannon Thermal Blanket System includes Integral Fasteners for installation.

* 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.
