INDUSTRIAL SAFETY ESTIMATION METHOD FOR AIR CHANNELS AND CHIMNEYS (VARIANTS) Russian patent published in 2005 - IPC

Abstract RU 2254427 C1

FIELD: industrial building, particularly for erecting towers, masts, poles, chimney stacks and water-towers.

SUBSTANCE: method involves testing metal chimney divided into i=1 - K_c zones, where K_c is total number of chimney zones counting from ground surface to determine outer diameter Di, m of chimney case zone, length Li, m of the chimney zone, height Zi, m from ground surface to lower section of chimney zone, chimney case thickness t_i,_p, m in the given chimney zone, wherein p=1 - N_mes, where N_mes - is number of performed measurements, deviation from circular shape, for instance in local flexed section, for value increasing design thickness t_i,_d, m and years of chimney operation beginning from year of chimney putting into operation up to year of test performing and calculating parameters of metal chimney, reinforced concrete chimney and brick one.

EFFECT: extended capabilities of safety estimation, provision of safe chimney operation.
