Question

why is charcoal not commonly used even though it is such a good fuel?​

Answer 1

Explanation:

Charcoal will go further if it is used efficiently and if its quality is optimum for the particular end use. Charcoal quality can be specified and measured in various ways which are usually derived from the various end use requirements. Efficiency in use normally means transferring the maximum amount of the heat content of the charcoal to the object to be heated, be it water for cooking, the air of a room, or the charge in a blast furnace. Efficiency depends on the use of properly designed charcoal burning equipment.
