Gas preheater resistance
Thread Content
After being used for a certain period of time, gas preheaters experience an increase in resistance.
It has the same problem: http://bbs.hcbbs.com/viewthread.php?tid=370674&highlight=%C3%BA%C6%F8%D4%A4%C8%C8%C6%F7
The increase in resistance in gas preheaters is mainly caused by the carbonization, adhesion, and accumulation of tar and other organic substances within them; altering the structure of the gas preheater or changing the heat medium can completely resolve such problems. Currently, the gas preheaters used by most enterprises are shell-and-tube heat exchangers, made of ordinary carbon steel, with steam being used as the heat medium ； I recommend replacing the gas preheater with BRQ series straight-plate heat exchangers, which are entirely made of 304 stainless steel; they are resistant to corrosion and scaling, and are inexpensive ； By switching the heat source to circulating ammonia water for heating, the above problems can be solved!
