TUBULAR HEAT EXCHANGER TYPE GAS-GAS

摘要

The object of the present invention is a tubular heat exchanger type gas-gas with vertically flowing gas streams which exchanging energy and which containing inside pipe spiral elements made of metal strip which adjacented to the internal surface of the pipe. Spiral elements inside pipes were caused axially-spiral gas flow inside pipes and intensification of heat transfer from gas to the inner surface of pipe. Tubular heat exchanger type gas-gas comprises a casting and disposed therein parallel pipes tightly connected sieve baffles which have inside spiral elements adjacent to the inner pipe surface is characterized in that spiral elements (2), is preferably a metal, is permanently fixed to the inner surface of each pipe (1).
