solid fuel
Coal or wood
Solid fuel is any combustible material that remains solid at ordinary temperatures—wood, coal, charcoal, peat, or compressed pellets.
The term distinguishes these from liquid fuels like gasoline or gaseous ones like propane.
Solid fuel powered human civilization from campfires through the industrial revolution: The cabin had a solid fuel stove for heating.
In rocketry, solid fuel refers to propellants that burn without external oxygen, packed into casings and ignited all at once.
