Theoretical approach for enhanced mass transfer effects in-duct flue gas desulfurization processes

Description: Bench-scale and pilot-scale experiments have been conducted to measure the mass transfer and kinetic rates at simulated duct injection conditions. Section 2 describes the tank reactor test results. The stirred tank reactor was used to study absorption of SO{sub 2} into saturated Ca(OH){sub 2} solutions with varied ionic strengths. The results of current experiments were compared with previous tests using saturated Ca(OH){sub 2} solution and 0.1 M CaCl{sub 2}. Section 3 summarizes the status of … more

LOFT CIS analysis: 24'' H and V Duct outside penetration S-12A

Description: The 24'' H and V Duct and related piping outside the LOFT containment and connected to containment penetration S-12A were analyzed to ASME Section III, Subsection NC (Class 2) criteria. The duct is part of the Containment Isolation System. The model considered the duct from the containment O.D. outward through the second isolation valve. Results of this analysis show that this section of the line will meet Class 2 requirements without modification.

Magnetic Measurements of the Background Field in the Undulator Hall with Ductwork and Cable Trays

Description: The duct work and cable trays present in the undulator hall facility are made out of potentially magnetically active materials. This note describes a measurement done to make a comparison between the fields in the undulator hall with the duct work and cable trays present and in the Magnetic Measurement Facility. In order for the undulators to have the proper tuning, the background magnetic field in the Undulator Hall must agree with the background field in the Magnetic Measurements Facility wit… more

FIELD EVALUATION OF IMPROVED METHODS FOR MEASURING THE AIR LEAKAGE OF DUCT SYSTEMS UNDER NORMAL OPERATING CONDITIONS IN 51 HOMES

Description: Duct leakage in forced-air distribution systems has been recognized for years as a major source of energy losses in residential buildings. Unfortunately, the distribution of leakage across homes is far from uniform, and measuring duct leakage under normal operating conditions has proven to be difficult. Recently, two new methods for estimating duct leakage at normal operating conditions have been devised. These are called the nulling test and the Delta-Q test. Small exploratory studies have bee… more
