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. Rub the meat with the remaining garlic mixture and olive oil. 2  Place pork loin into oven, turning and basting with pan liquids. 3  Cook until the pork is no longer pink in the center, about 1 hour. 4  An instant-read thermometer inserted into the center should read 145 degrees F (63 degrees C). 5  Remove roast to a platter.
1 Roast the pork for 10 minutes: Set the pork in the pan. (It's fine if your pork tenderloin is a little long for the pan; just bend it to fit as we did here.) Return the pan to the oven. Roast for 10 minutes.  Flip the pork, reduce the heat, and roast another 10 to 15 minutes: Flip the pork to the other side. Reduce the oven temperature to 400Â°F and continue roasting another 10 to 15 minutes. The pork is done when its internal temperature registers 140Â°F to 145Â°F in the thickest part of the meat (20 to 25 minutes total).
