BS 6466:1984 pdf free.Code of practice for design and installation of ceramic fibre furnace linings.
This code of practice recommends good working practice for the design and installation of insulating linings for furnaces where ceramic fibrous materials comprise the whole or a significant part of the lining. The code is concerned with furnaces generally operating at temperatures of 800 °C and over and mainly with clean conditions; abrasion and slagging, etc are excluded.
NOTE 1 This code is intended to be read in association with
BS 7225-3.1.
NOTE 2 The titles of the publications referred to in this standard are listed on the inside back cover.
2 Definitions
The definitions given in BS 3446-1 apply, together with the following.
2.1
sprayable ceramic fibre
a system comprising pre-treated bulk fibre blended with a non-corrosive binder system. The system is capable of being applied by means of a spraying device or gun in order to form a monolithic lining which can be applied rapidly.
2.6
pleated blanket module
a construction in which a continuous length of ceramic fibre blanket is pleated in such a way that the fibre orientation is substantially normal to the plane of the lining.
2.7
overlapped joint
a single layer of ceramic fibre blanket is applied to overlap the adjacent blanket.
2.8
shingled joint
a method of applying double layers of ceramic fibre blanket in such a way that half the width of each layer overlaps half the width of the adjacent layer.
2.9
tip temperature
the highest temperature of a metal component in a lining close to the hot face.
3 Design criteria
NOTE It is important not only that the design criteria should be understood and agreed but also that there should be a common
basis when contractors are tendering.
3.1 Design of furnace linings should be based on the following objectives:
a) to achieve the required thermal design criteria including agreed thermal resistance, thermal capacity or both;
each of the component parts of the lining, both
b)to ensure that the operating temperatures for metallic and ceramic, will be acceptable in relation to the expected life;
c)to ensure similarly that the mechanical
construction is suitable for the expected duty and d)to ensure that all significant features of the construction are given approprlate attention
while at the same time not precluding the installation contractor from applying his experience and utilizing improved techniques, etc;BS 6466 pdf download.
