Why do haystacks spontaneously combust?

Spontaneous combustion inside haystacks is when moisture builds up inside a bale. That moisture starts to heat up and the oxygen inside the hay combines with it and causes a slow burn that eventually destroys the entire stack.

In respect to this, why do haystacks catch fire?

High-moisture haystacks and bales can catch on fire because they have chemical reactions that build heat. When hay's internal temperature rises above 130 degrees Fahrenheit (55 degrees Celsius), a chemical reaction begins to produce flammable gas that can ignite if the temperature goes high enough.

Also, why does linseed oil spontaneously combust? Linseed oil evaporates very rapidly causing an exothermic reaction, which accelerates as the temperature of the rags increases. When the accumulated heat exceeds the rate of heat dissipation, the temperature increases and may eventually become hot enough to cause the rags to spontaneously combust.

Also asked, why does sawdust spontaneously combust?

Combustion happens when a material reacts with oxygen and gives off heat. Sawdust is another material that is prone to spontaneous combustion, and the risk of spontaneous combustion from sawdust increases when doing refinishing work due to the presence of finish and possibly other volatile solvents in the sawdust.

What oils can spontaneously combust?

Linseed oil and cottonseed oil are materials that can cause spontaneous combustion when disposed of improperly.
