IF A MUFFLER IS USED OVER THE BLEEDERS, WHAT EVIDENCE DOES THE FIRM HAVE THAT IT DOES NOT RESTRICT FREE FLOW OF STEAM? (113.87(g))

(SHOULD REQUIREMENT)

BLEEDERS ON CRATELESS RETORTS
FOR RETORTS HAVING A TOP STEAM INLET AND BOTTOM VENTING, A BLEEDER SHALL BE INSTALLED IN THE BOTTOM TO REMOVE CONDENSATE ­ 113.40(a)(8). IT IS RECOMMENDED THAT THERE BE 1 OR MORE 3/8-INCH OR LARGER CONDENSATE BLEEDERS AT THE BOTTOM OF THE RETORT. IN ADDITION, WHEN A FALSE BOTTOM (A PERFORATED STEEL PLATE) IS EMPLOYED, IT IS USEFUL TO HAVE A 1/8-INCH BLEEDER WITH ITS OPENING AT A POINT HIGHER THAN THE CONDENSATE BLEEDER AND JUST BELOW THE FALSE BOTTOM (SEE NFPA BUL 26-L, 13TH EDITION, P. 14 AND LACF FIELD GUIDE-PART 2, P. 26). IN SOME SYSTEMS, A CONDENSATE TRAP MAY BE USED TO COLLECT CONDENSATE BUILDUP AT THE BOTTOM OF THE RETORT IN LIEU OF A STEAM CONDENSATE BLEEDER ­ IN THIS CASE, THE REMOVAL OF CONDENSATE MAY NOT BE VISIBLE, HOWEVER, A VISIBLE STEAM BLEEDER SHOULD BE LOCATED ABOVE THE CONDENSATE TRAP (JUST BELOW THE FALSE BOTTOM). THIS STEAM BLEEDER SHOULD EMIT ONLY STEAM AND NO CONDENSATE OR WATER DURING THERMAL PROCESSING.

Yes IF SO, REPORT THE NUMBER AND DIAMETER OF THE BLEEDER(S):

DOES THE OPERATOR OBSERVE A FREE FLOW OF STEAM FROM THIS BLEEDER PRIOR TO BEGINNING THE RETORT THERMAL PROCESS TIMING AND AT INTERVALS OF SUFFICIENT FREQUENCY DURING THE PROCESS? .......... Yes No ARE THESE OBSERVATIONS RECORDED AT THE TIME THEY ARE MADE? ........................................................... Yes COMMENTS: No

IF A STEAM CONDENSATE BLEEDER(S) IS PRESENT, DOES THE OPERATOR ALSO OBSERVE THE FREE FLOW OF STEAM CONDENSATE FROM THIS BLEEDER JUST BEFORE AND DURING THE THERMAL PROCESS? ........................ Yes No ARE THESE OBSERVATIONS RECORDED AT THE TIME THEY ARE MADE? ........................................................... Yes COMMENTS: No
