J */ /I / d June 17, 1966 Ki, E, Haley, Supto Blast; Furnace Middletown Works From: So A, Bell Subject: Under-Hearth Cooler - Middletown Blast Furnace The attached two curves summarize the data through March 1966 Figure 1 is the temperature distribution across the furnace* Note that the maximum temperature on top of the plenum, and at its edge, was 2?0F. This is well within the design limit usedo The scatter of' points beyond the plenum edge probably is due to the proximity of a given thermocouple to an outlet pipeo The influence of hearth jacket cooling is apparent beyond the 10 foot radiuso Figure 2 shows the trend of each of the 1$ thermocouples with time* X plan to up date this chart periodically<> Figure ,jt shows the approximate location of each thermocouple * SAB/bms cc: W0 F,, Dannecker Ho L,, Osborne No To Kurfiss Co Fo Staley Ho Holiday Jo Poast Lo Jo Trauthwein Jo Lo Brady J o Pugh Eo Fo McKinney Bo Ho Realms Po Go Sammet Lo Ceseaux Co Ho Leinert Wo Ec Marshall To Fo Qlt A-o Po Kerschbaura 4, a.
