Blanket insulations

Solid walls can only be improved either by removing the internal plaster layer and providing suitable blanket insulation fixed to battens and then covering with the required... 

Blanket Insulation. A relatively flat and flexible insulation in coherent form furnished in units of substantial area. Some forms are called baits. 

Blanket Insulation, Metal Mesh. Blanket insulation covered by flexible metal-mesh lacings attached on one or both sides... 

The arch is made of cast iron or steel and sits under the pans to contain the heat. Oil-fired units have the burner located at the front, slanting upward, and with the fire pointing towards the rear (stack). The inside of an oil-fired arch is lined with ceramic blanket insulation. Wood-fired... 

The distillation column should be well insulated to prevent loss of heat and to protect against bums. Two to three inches of fiberglass blanket insulation is good. On columns located outdoors because of size and safety, the insulation blanket will shield the column from increased heat loss due to wind currents. Exposed insulation blanket may require weather shielding to maintain its performance. 

Refractory materials can be melted, spun, and blown into fiber strands similar to wool or blanket insulations. They are used in many medium- and low-temperature furnaces and ovens furnaces, and for outer layers in multilayered refractory walls. Because of all their small air spaces, they are much better insulators than solid refractories, but they are more fragile, less durable, and more difficult to install so that they do not settle, shrink, or otherwise lose their good insulating property. Many of the suggestions in a later section on insulation installation can apply to fiber refractory installation. 

Soft, flexible blanket insulations are often the outer layer of a furnace or oven. To diminish outer surface heat loss, follow these admonitions ...

Flexible blanket insulations have proven to provide snbstantial noise attenuation, be easy to remove and reinstall during equipment maintenance, and be cost effective in many applications requiring ready access to the equipment. Information about thermal-acoustic flexible blanket insulation is available from many manufacturers of industrial blanket insulation and in the sources listed at the end of this chapter.
