The Beckett System Recovery and Utilization of Low Grade Waste Heat From Flue Gas

The Beckett Heat Recovery is a series of techniques for recovering low-grade waste heat from flue gas. Until the cost of fossil fuels began rising rapidly, flue gas below 600 F was considered economically unworthy of reclaim. This paper will describe the latest system installation at the John Deere WeIland Works. Partially funded by the Canadian and Ontario Governments in order to demonstrate new energy saving technology, the Beckett Model 2002 employs a heat exchanger which does double duty. During low demand periods, the unit is gas-fired and produces 150 psi steam at high efficiency. In the fall, the heat exchanger is converted to accept flue gas from the large original water tube boilers. The flue gas heats water, which preheats make-up air and boiler feedwater. Several of the Beckett Systems presently operating use year-round heat recovery exchangers on constant loads. The newest development is the Series 2004 condensing system that reduces flue gas temperature to within 15 F of the heat sink medium

Cavernous transformation of the portal vein associated to multiorgan developmental abnormalities

Initial diagnosis of cavernous transformation of the portal vein (portal cavernoma) is rarely made in adults. Its main clinical manifestation is upper gastrointestinal hemorrhage due to variceal bleeding. More rarely, diagnosis is made from obstructive jaundice. In children, this condition is frequently associated to prehepatic portal hypertension and congenital anomalies, the most frequent of which are atrial septal defects or malformations of the biliary tract or of the inferior vena cava. We describe here a case of a 23-year-old female presenting with massive hematemesis due to the presence of esophageal and small intestinal varices. She had a cavernous transformation of the portal vein with prehepatic portal hypertension associated with heretofore unreported malformations such as right pulmonary hypoplasia, cardiac dextroposition, and right renal ectopia. A unifying hypothesis (e.g. an intrauterine vascular insult) to explain the pathogenesis of these defects seems unlikely. Appropriate tests failed to identify specific functional abnormalities in these organs. Although she bled more than once, the combination of sclerotherapy and b-blockers has been, thus far, able to control the major clinical consequences of this diseas
