16 Among fuels, kerosene oil is the cheapest; gas gives the greatest amount of heat in the shortest time. Soft wood, like pine, on account of its coarse fibre, burns quickly; therefore makes the best kindling. Hard wood, like oak and ash, having the fibres closely packed, burns slowly, and is used in addition to pine wood for kindling coal. Where only wood is used as a fuel, it is principally hard wood.

Charcoal for fuel is produced by the smothered combustion of wood. It gives an intense, even heat, therefore makes a good broiling fire. Its use for kindling is not infrequent.

There are two kinds of coal: Anthracite, or hard coal. Examples: Hard and free-burning White Ash, Shamokin, and Franklin. Nut is any kind of hard coal obtained from screenings. Bituminous, or soft coal. Example: cannel coal.

Coke is the solid product of carbonized coal, and bears the same relation to coal that charcoal bears to wood.

Alcohol is employed as fuel when the chafing-dish is used. Fire for cookery is confined in a stove or range, so that heat may be utilized and regulated. Flame-heat is obtained from kerosene, gas, or alcohol, as used in oil-stoves, gas-stoves or gas-ranges, and chafing-dishes.

A cooking-stove is a large iron box set on legs. It has a fire-box in the front, the sides of which are lined with fire-proof material similar to that of which bricks are made. The bottom is furnished with a movable iron grate. Underneath the fire-box is a space which extends from the grate to a pan for receiving ashes. At the back of fire-box is a compartment called the oven, accessible on each side of the stove by a door. Between the oven and the top of the stove is a space for the circulation of air.

Stoves are connected with chimney-flues by means of a stovepipe, and have dampers to regulate the supply of air and heat, and as an outlet for smoke and gases.

The damper below the fire-box is known as the front damper, by means of which the air supply is regulated, thus regulating the heat.
