Fire balls

The fire spreads easily by, e.g., running liquid fire, a pool fire, a fire ball, heat radiation or thermal lift (convection). 

Ball valves are limited in temperature by the elastomer material used in their seats. Many designs have a secondary metal-to-metal seat to provide a seal in case of fire. Ball valves are not suitable as a throttling valve, but can be used on start-up and shut-down in the partially open position to bleed pressure into or out of a system. 

Fallout plutonium arrives in natural waters either by direct atmospheric deposition or by erosion and/or dissolution from the land. Although in the past, this plutonium was considered to be in a refractory form due to formation within the fire ball, it seems more likely that most of the plutonium originated in the stratosphere by the decay of 239Np (from 239U formed during the detonation)(4). Deposition occurs predominantly with one or a few atoms incorporated in a raindrop. Investigations by Fukai indicate that collected rain contains soluble plutonium which has oxidation states that are almost totally Pu(V+VI)05). 

More specific results are beyond the scope of our limited presentation for plumes. However, we will examine some gross features of transient plumes namely (a) the rise of a starting plume and (b) the dynamics of a fire ball due to the sudden release of a finite burst of gaseous fuel. Again, our philosophy here is not to develop exact solutions, but to represent the relevant physics through approximate analyses. In this way, experimental correlations for the phenomena can be better appreciated.

Reilly (Ref 1) describes a gray mixt made by mixing 7 parts of meal powder with 100 parts of sulfur, and is mostly used for the manuf of fire balls (used in war). These consist of twill bags, charged with compressed gray mixture, which is filled into them with the aid of spirit they are fired by means of a composition fuse. Gray mixture mixed with antimony sulfide is used for torches.

At the end of the fifties, Ya.B. gave a qualitative picture of the structure of shock waves with radiation transfer taken into account [20], In front of a compression shock there is a layer heated by radiation from the compressed gas. Behind the discontinuity there is a temperature peak. The simultaneously developed quantitative theory of these effects allowed detailed explanation of the experimentally observed patterns of luminescence of the front in strong shock waves and of the radiation in the early stage of a fire ball in...

We used to make a different version of Joe Brown s Fire Ball Cannon. Ours was hand-held. You squirt the lighter fluid into the hole at the bottom and then whip the taped together cans up and down in a stiff-arm motion as though you were going to beat the ground with it. You then take a match which is lit and hold it by the hole - boom WHEEl...
