Investigation on the economizer
Thread Content
For sulfuric acid production plants built after 2000, please share information on what type of economizer is used (heat pipe economizer, conventional economizer, or economizer with automatic preheating), what the exhaust temperature of each type of economizer is, which manufacturers produce them, and how well they perform. Please reply! My previous plant used a 400kt/a sulfur-based sulfuric acid production system with heat pipe economizers; the exhaust temperature for the first economizer was 185 degrees, and that for the second economizer was 180 degrees. These economizers were manufactured by Jiangsu Shengnuo, and they performed well from 2000 to 2006.
Our company uses a 380kt/a sulfur-based sulfuric acid production system equipped with heat pipe economizers; the exhaust temperature of the first economizer is 170 degrees, while that of the second economizer is 135 degrees. These equipment were manufactured by Shanghai Hailu Kunlun High-Tech Co., Ltd., and have been in use since 2003 to date. There is virtually no condensed acid, and no leakage incidents have occurred.
Shanghai Hailu High-Tech Engineering Company designs and manufactures heat pipe economizers and heat pipe exchangers for sulfuric acid production plants of various scales. It has a low flue gas temperature, so there is no dew point corrosion. Engineering examples: Zhangjiagang Shuangshi 1,000 kt/a, Jiaxing Jiahua 30 kt/a, etc.
What is the actual control temperature for smoke exhaust in twin lion systems?
The exhaust temperature in Province 1 is 165 degrees, while it is 135 degrees in Province 2.
