A condensing economizer can increase overall heat recovery and steam system efficiency by up to 10 percent by reducing the flue gas temperature below its dew point, resulting in improved effectiveness of waste heat recovery.
1 Place pork loin into oven, turning and basting with pan liquids. 2  Cook until the pork is no longer pink in the center, about 1 hour. 3  An instant-read thermometer inserted into the center should read 145 degrees F (63 degrees C).4  Remove roast to a platter.

Pork is cooked in minutes per pound. So roast a tenderloin at 425 degrees F for 15-20 minutes per pound and grill it over medium coals for 15-25 minutes per pound. The internal temperature should be a minimum of 145 degrees F (the USDA lowered the safe temperature for pork in the summer of 2011).
