Question

Define ignition temperature.

Answer 1

Temperature is an actual amount that expresses hot and cold. It is the indication of thermal energy, present in all matter, which is the source of the event of heat, a progression of energy when a body is in touch with another that is colder or warmer. The least hypothetical temperature is absolute zero, at which not no more thermal energy can be removed from a body. Tentatively, it must be drawn nearer intently (100 pK), however not reached, which is perceived in the third law of thermodynamics.

Complete answer:
The ignition temperature of a substance is the minimum temperature at which the substance bursts into flames for spontaneous combustion. The ignition temperature is otherwise called ignition point. The ignition temperature of fuel can be characterized as the minimum temperature to which fuel should be heated so that it might burst into flames and start burning.
Ignition temperature is a significant property of any fuel in light of the fact that the burning response of the fuel gets self-supporting just over this temperature. In an ordinary gasifier, a specific measure of burning is important to give the energy needed for drying and pyrolysis lastly for the endothermic gasification reaction.

Note:
The ignition temperature is by and large lower for higher volatile matter content fuel. Since biomass particles have a higher unstable matter substance than coal, they have an altogether lower ignition temperature. Ignition temperature, notwithstanding, isn't really an extraordinary property of fuel since it relies upon a few different variables like oxygen, partial pressure, molecule size, rate of heating, and a particle’s thermal surroundings.
