Abstract
A debris filter trap to prevent potentially damaging debris carried by the feedwater entering the pressure vessel of a once through steam generator from entering into the section of tubes which are positioned within the confines of an integrally contained economizer of the once through steam generator. The trap will remove foreign material, from the feedwater flow, that is larger than the space between the tubes, and thus prevent debris particles that are large enough to get lodged in the tube spacing from entering the economizer.
