Can kerosene burn hot enough to melt steel?
Lapin should realize that jet fuel fires cannot burn hot enough to melt steel. Jet fuel is not much more than kerosene, which at the very best will burn at about 1,600 degrees. Steel will not melt until temperatures get to at least 2,700 degrees and yet photos show molten steel pouring down the side of the buildings.
From here, for instance, you can get an approximate maximum flame temperature for kerosene burning in air, and a higher concentration of oxygen will increase the temperature. At 3800 F, this is about 1000 F above the melting point of steel, so melting steel with jet fuel (kerosene) is entirely possible.
Kerosene vapor diffused in air (as from a lamp wick) will burn at a maximum flame temperature of 990 °C (1814 °F). In a stochiometric mixture with oxygen the flame temperature of kerosene can reach 2393 °C (3801 °F).
While jet fuel, which burns at around 800 to 1,500 degrees Fahrenheit, may not reach the 2,750-degree melting point of steel, it is only about half as strong at 1,100 degrees, according to a comprehensive report compiled by Popular Mechanics in 2005.

Flash Point & Autoignition Temperature.
| Fuel Gas | Max Temperature |
|---|---|
| Acetylene | 3300°F |
| Propane | 2800°F |
| Hydrogen | 2650°F |
| MAPP® | 2900°F |
The melting point of steel ranges from 2500-2800°F or 1371-1540°C.
Kerosene has a lighter viscosity than diesel, so it will burn hotter. This can help heat the house, but it could also cause some problems for a heater not equipped to handle heat that's hotter than what is typical for heating oil.

Kerosene due to its density, has less lubricity which can result in the multiple wear and tear in the mechanism of automobiles which can burnout and being highly combustible, it might result in serious incidents.

Due to the property changes deformations and buckling can occur at 600°F. If a structural steel framing member, such as a beam or girder, is completely constrained at its connections, deformation and buckling can occur as low as 250°F.
Both Jet A and Jet A-1 have a flash point higher than 38 °C (100 °F), with an autoignition temperature of 210 °C (410 °F).
Kerosene is another acceptable alternative to home heating oil of the type known as No. 2, a designation that indicates its weight and grade. Almost all home heating oil is No. 2; if you happen to burn a different weight of oil, diesel may not be an acceptable substitute.
Kerosene has a higher viscosity and lower density than typical heating oil, which means that it has a lower flash point. Kerosene gives off flammable gases when it is heated to approximately 100 degrees Fahrenheit, which does make it a slightly greater fire and explosion risk than heating oil.
Jet-A (freeze point of -40°C) and Jet-A1 (freeze point of -47°C) are highly refined kerosene-type fuels used in commercial and general aviation turbine engines.
Argon. Argon, an inert gas, is commonly used in applications across metals production operations to improve quality, and increase efficiency and yield.
A MAPP/oxygen flame is not entirely appropriate for welding steel, due to the high concentration of hydrogen in the flame – higher than acetylene, but lower than any of the other petroleum fuel gases. The hydrogen infuses into the molten steel and renders the welds brittle.
Kerosene is less volatile than gasoline. Its flash point (the temperature at which it will generate a flammable vapour near its surface) is 38 °C (100 °F) or higher, whereas that of gasoline is as low as −40 °C (−40 °F). This property makes kerosene a relatively safe fuel to store and handle.

Can lava melt steel?
Steel often melts at around 1370 degrees Celcius or 2500°F. Most lava is between 700 to 1200 degrees Celsius, so most lava won't melt steel.
The temperature of a fire can reach up to 1,100 degrees Fahrenheit. Fire can't melt everything, but it can melt steel which has a melting point of 2,500 degrees Fahrenheit. There are few things as entrancing as a campfire, or any fire for that matter.
Kerosene can be mixed with diesel fuel to gain a couple of benefits. In the winter time, kerosene is extremely useful for changing the cold weather handling temperatures of diesel fuel.
The effects of blending gasoline with kerosene are increased density, decreased volatility and reduced octane rating (Fonseca et al., 2007).
In most cases one or two "fills" of petrol contaminated with kerosene is enough to disable an engine. The kerosene causes "coking," a build up of carbon deposits that causes irreparable damage. The engine loses power, misfires and the engine warning light illuminates.
It preserves metal parts and does not cause rusting after cleaning.
The temperature of a fire can reach up to 1,100 degrees Fahrenheit. Fire can't melt everything, but it can melt steel which has a melting point of 2,500 degrees Fahrenheit.
A simple wood fire will provide all the heat needed to melt either metal.
Structural steel can withstand approximately 425°C before it begins to soften. Between 600°C and 650°C, the steel will lose half of its strength, and will pose a risk of failing (depending on the load it bears). Unsurprisingly, even a house fire will reach very high temperatures of around 600°C or just under.
