| Abstract: | Fundamental reasons for scaling and blocking in gas-gas heater(GGH),such as gas with gypsum,poor defogging effect,insufficient purge,degradation of coal type and limestone quality and other factors are concretely analyzed,and targeted improvement approaches are proposed: redevelop the GGH equipment by installing deflector and carry on operation adjustment.After the improvement,problems concerning scaling and blocking in GGH and rise of differential pressure get relieved. |
