Correlation and prediction of saline solution properties for their use in mineral processing using artificial neural networks
Artificial neural networks (ANNs) are applied to correlate and predict physico-chemical, transport and thermodynamic properties of seawater. Values of these properties are needed in the design, simulation and optimization of processes in which seawater is used, mainly in the mining industry. Density, vapor pressure, boiling temperature elevation, specific heat, viscosity, thermal ...

Accuracy in temperature sensor response time estimation for new nuclear reactor designs
One method for measuring the response time of temperature sensors, the plunge test, verifies that the sensor has a suitable response time in the laboratory before installation. However, plunge test results cannot be extrapolated to the response time in an operating plant because response time is affected by multiple factors such as the ratio of internal heat-transfer resistance to the surface ...

Application and precautions of various ceramic crucibles
As an important part of chemical equipment, crucible is a container for melting and refining metal liquid and heating solid-liquid reaction, which is the basis for the smooth progress of chemical reaction. Crucibles were originally made of clay, and one of the earliest uses of platinum was to make crucibles. With the development of manufacturing technology, crucibles can now be composed of any ...

boiler soot blower
During the combustion of pulverized coal in boiler, coal will turn into slag and get discharged, but still some unburnt carbon, volatile matters, fly ash will go with flue gas. These things will cool off and adhere to heating surface. They settle down on heating surface to cause problem called soot fouling and slagging. Boiler soot blower could keep boiler clean. Here are 4 reasons why it is ...

An analysis of the environmental management elements related to the improvements of the drying kinetics of waste activated sludge by Fenton peroxidation
Advanced sludge treatment processes (AST) reduce the amount of sludge produced and improve the dewaterability, thus probably also affecting the heat transfer properties and the drying characteristics of the sludge. This paper studies the influence of the Fenton peroxidation on the thermal conductivity of the sludge. Results demonstrate that the Fenton's peroxidation improves the sludge cake ...

Experimental determination of heat transfer coefficients in uranium zirconium hydride fuel rod
The heat generated by nuclear fission is transferred from fuel elements to the cooling system through the fuel-to-cladding gap and the cladding-to-coolant interfaces. The fuel thermal conductivity and the heat transfer coefficient from the cladding to the coolant were evaluated experimentally. A correlation for the gap conductance between the fuel and the cladding was also presented. As the ...
