POLYMER COMPOSTE GAS EXHAUST PIPES IN CHIMNEYS OF LARGE-SCALE POWER INDUSTRY
Abstract
Combustion gases at large Russian power plants are removed through cast-in-block concretepipes with the height of 100–370 m; and their number is over 800. The changes in the structure of
fuel balance, modern trends in the efficient use of energy and resources as well as environmental requirements
change the terms of pipe service and lead to their fast wear process. The installation of
inner polymer composite gas exhaust pipes and mainly glass fiber plastic is a revolutionary method
of increasing the life time of concrete gas exhaust pipes in power industry. Compared to steel pipes
the use of glass fiber plastic makes it possible to get more durable, light and fast assembled gas exhaust
pipes consisted of coiling solid drawn elements (cylinder shell) which has economic benefits.
Proved technical solutions on double jointing of glass fiber plastic cylinder shells given in the article
contribute to considerable price reduction for suspension structures and pipes as well as to assembling
time period reduction. Developed and implemented spade convergent tubes, elements of
which are made by coiling (the transition from the bottom part of gas exhaust ducts of chimneys to
the gas fiber plastic pipes) are the easiest and the most economically effective technical solution in
comparison with traditional convergent tubes. The production of inner polymer composite ducts of
vertical coiling with a coiler inside a chimney stack is the most efficient in deletion of the process of
canting cylinder shells and their pre-assembling. The assessment of efficiency of the given variant
compared to the installation of a metal gas exhaust duct is performed.
Keywords: chimney exhaust pipes, reconstruction, glass fiber plastic.
