Title:
HEAT RESERVING WORKING METHOD FOR HIGH TEMPERATURE PIPE
Document Type and Number:
Japanese Patent JPH0634093
Kind Code:
A
Abstract:
PURPOSE: To provide a heat reserving working method capable of reducing both the heat loss caused by the leakage of the air warmed by a high temperature pipe out of a heat insulating material and the loss caused by the radiation from the high temperature pipe and improving plant efficiency by reducing the radiation los from the high temperature pipe.
CONSTITUTION: The circumference of a high temperature pipe 2 is covered by a first fiber heat insulating material 6, and the circumference of the first heat insulating material is covered by high reflectance gold foil 8, and then the circumference of the gold foil is covered by a second fiber heat insulating material 10.
