Standard Guide for Design and Construction of Brick Liners for Industrial Chimneys — 13 стр.
Значение и использование

History:

4.1.1 For many years, brick liners have been used with an excellent record of performance. For the most part, however, the design and construction of brick liners has been based on past industry practice due to the lack of available information and knowledge of the physical properties of the brick and mortar, the thermal and seismic behavior of brick liners, and many related characteristics that were not properly or accurately defined.

4.1.2 The use of scrubbers, which lower gas temperatures and introduce highly corrosive condensates into the flue gas system, requires many new design considerations. The effect that scrubbers have on brick liners is an ongoing area of study, since a number of liners have experienced growth- and deflection-related problems which may be attributable, at least in part, to nonuniform temperature and moisture conditions within the liners.

PurposeThe recommendations contained herein represent current industry practices and serve to define the pertinent considerations that should be followed in the design and construction of brick chimney liners.

Область применения

1.1 This guide covers procedures for the design, construction, and serviceability of brick liners for industrial chimneys. The structural design criteria are applicable to vertical masonry cantilever structures supported only at their base, either by a foundation, a concrete pedestal, or by some means from the outer concrete shell. Excluded from direct consideration are single-wythe, sectional brick linings that are supported on a series of corbels cast in the outer chimney shell.

1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
