Question

why fuel should have low ignition temperature but well above the room temperature?​

Answer 1

Answer:

The ignition temperature is the temperature at which fuel catches fire. If ignition temperature is low below the room temperature the fuel will easily catch fire if kept in the room and we don't want that . The ignition temperature of a good fuel should be above room temperature

Answer 2

Answer:

fuel should have low ignition temperature but well above the room temperature

Explanation:

Ignition temperature of coal and other dust is not affected by particle size. A big difference is made by the way coal dust comes in contact with a heat source. Thus, layered powder of coal can ignite at a much lower temperature (160°C approx.), whereas a cloud of coal dust will need 450–650°C to ignite.
