Investigation of methods to transfer heat from solar liquid-heating collectors to heat storage tanks. Final report (open access)

Investigation of methods to transfer heat from solar liquid-heating collectors to heat storage tanks. Final report

A study was made of the methods available to transfer heat from the collector to the water storage tank in water heating systems. In counterflow heat exchangers used in double loop water heating systems, it was found to be more important to use a high water flowrate than a high heat transfer fluid flowrate. It was earlier thought to be best to have matched WC/sub p/ (mass flowrate-specific heat) products in the loops. It was shown in this study that the water WC/sub p/ product should be about twice as large as that of the heat transfer fluid. It was found that neither the heat exchanger type nor the size was very critical, so that very simple criteria were adequate in determining optimum heat exchanger size. It was found that there is a definite system size below which one should use a traced tank or a coil in a tank. Equations and optimization criteria were developed for traced tanks or tanks with coils. At present, there is no quantitative understanding of liquid to liquid (direct contact) heat exchangers, though they are clearly quite effective. Draindown systems are discussed, and several appendices are included on heat transfer and other characteristics of …

Sulfur resistant methanation catalyst. Final report, July 1, 1975--January 31, 1978 (open access)

Sulfur resistant methanation catalyst. Final report, July 1, 1975--January 31, 1978

The purpose of this work was to develop a catalyst which would methanate a gasified-coal stream without prior sulfur removal. Fifty-eight activity tests have been completed on forty-nine different catalyst compositions which were studied as sulfur-resistant methanation catalysts. Most of the base-metal catalytically-active, transition elements were used to prepare the catalysts. These metals were combined or used singly with carriers such as alumina, silica, chromium oxide, magnesium oxide, magnesium silicate, and magnesium aluminate to provide the test catalysts for this work. In addition, a number of catalysts of identical chemical composition were prepared by several formulation methods. Test conditions, including temperature, gas composition, and steam levels were varied during the course of the work and computer data processing was used to analyze the test results. Two catalysts, namely nickel and chromium on magnesium silicate and nickel and chromium on magnesium aluminate, converted all of the carbon monoxide and part of the carbon dioxide to methane at 500/sup 0/F when reduced with only hydrogen and no sulfur in the process gas. This is equivalent to the performance of nickel-SNG type methanation catalysts. After sulfiding, the nickel--chromium on magnesium silicate catalyst retained a 60 to 80% methanation activity at 1100/sup 0/F with …

Recirculating flow analyses of Intermediate Size Inducer Pump (ISIP)

This report documents the recirculation flow analyses for the Intermediate-Size Inducer Pump (ISIP), from which the primary flowrates through the pump were obtained. The front and rear impeller labyrinth seals, which incorporate stepped pockets with slanted and rounded ribs were checked. These seal design features should minimize the impeller labyrinth seal leakages and also provide excellent shutoff head characteristics.

Possible variations in atmospheric ozone related to the eleven year solar cycle (open access)

Possible variations in atmospheric ozone related to the eleven year solar cycle

Changes in ozone and other minor constituents resulting from eleven year variations in the solar flux between 180 and 300 nm reported by Heath and Thekaekara (8) are presented. Results were computed using a one-dimensional time dependent model that allows for all major feedbacks and time delays which may result from changing photolysis rates in the O/sub x/--NO/sub x/--HO/sub x/--ClO/sub x/ system. Since the 1950's the chlorine content of the stratosphere has been increasing. The effect of this increase on ozone variability during the last two solar cycles is analyzed. Expected variations in O/sub 3/ resulting from changes in the uv flux are compared to available measurements of total O/sub 3/.
