(HEI-2954) PDF - STANDARDS AND TYPICAL SPECIFICATIONS FOR TRAY TYPE DEAERATORS, 11TH EDITION
Standards
Full Description - PDF Version
The Deaerator Section of the Heat Exchange Institute has developed the Eleventh edition of this Standard. The material in this Standard has been selected to incorporate the safest available design criteria, as well as the highest levels of deaerator performance. This Standard contains practical information on the design, construction, and operation of tray type deaerators. It is intended to serve as a guide for individuals who design, specify, purchase, and use tray type deaerators. This Standard has been renamed from its original edition and the content revised to reflect the Institute’s position that the tray type deaerator is the superior design type with regard to corrosion resistance and turn down performance. This Standard reflects the collective knowledge and experience of the Deaerator Technical Committee, and is reviewed and discussed during regularly scheduled meetings. This process insures that the Standard will be regularly updated to reflect the changes in technology, codes, and member experience. This Standard continues to be influenced by the work of other organizations, such as American National Standards Institute (ANSI), American Society of Mechanical Engineers (ASME), American Society for Testing Materials (ASTM), NACE International, The Corrosion Society, and the Technical Association of the Pulp and Paper Industry (TAPPI). Special consideration and credit is given to NACE and TAPPI, for their extensive research on deaerator pressure vessel cracking. Particular attention and credit is given to NACE Standard SP0590. Adherence to this Standard is strongly recommended. Comments and suggestions for the improvement of this Standard are always welcome and should be directed in writing to the Deaerator Section at the Institute’s address.
