What is the definition of heatingsurface area of a AFBC boiler?
The heating surface area of an Atmospheric Fluidized Bed Combustion (AFBC) boiler refers to the total surface area within the boiler where heat is transferred from the combustion gases to the water or steam. This area includes the surfaces of the furnace, convection sections, and any superheaters or economizers. A larger heating surface area can enhance heat transfer efficiency and improve overall boiler performance. Proper design and sizing of this area are crucial for optimizing combustion and ensuring effective energy conversion.

How weeping avoid in distillation column?
Limiting the hole area to 13-14% prevents weeping in distillation columns. This may be limited by the allowable pressure drop specified for the column (too little leads vendors to specify a higher % hole area, thus causing weeping).
'If you become contaminated after a chemical attack you should be processed through the contamination control area within 24 hours of contact with chemical agents.?
TRUE
How did the Valero McKee refinery get its name?
This is speculation. The Ordovician? McKee formation has been a producer in the Permian Basin/Panhandle area. Before formal statigraphic correlations were made, the "McKee" may have been a producer in the area. Sometimes site names are taken from towns. ranches, formations, or geographic/geologic features. To my knowledge there is no settlement, unless it was a ranch or tract owner, with the name of McKee.
How does interfacial energy vary with coherence?
Think of a high angle grain boundary. The structure is very disordered there and bonds have been broken. Thus, the interface is unstable and high in energy. Thus, coherence leads to lower interfacial energies. The degree of coherence dictates the interfacial energy, so the most coherent interface will have the lowest interfacial energy.

What is exactly meant by interficial velocity?
Interfacial velocity is the speed of a fluid whose movement is generated by its mass transfer from a phase to the next . Another factor that generates interfacial velocity is the bulk motion of the fluid, known as advection.
What is interfacial tension of toluene and water?
37.1 miliNewtons/Meter - or in different units - 0.0371 N/M. Taken from: "Interfacial Tension of Toluene + Water + Sodium Dodecyl Sulfate from (20 to 50) °C and pH between 4 and 9"J Saien et al. J. Chem. Eng. Data 2006, 51, 1832-1835
What does the term interfacial tension mean?
The term interfacial tension or surface tension means the contractive tendency of a liquid that lets it resist and external force. Interfacial tension could be observed from the floating of objects on the surface of water, even though they are more dense than water.

What is the difference between surface tension and interfacial tension?
interfacial tensions are similar to surface tensions in which cohesive forces are also involved but the major forces are adhesive forces (tension) between liquid phase of one substance and either solid liquid or gas phase of another substance and interaction occurs at their surfaces
