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

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.

The oven is heated by a circulation of hot air. This is accomplished by closing the oven-damper, which is situated near the oven. When this damper is left open, the hot air rushes up the chimney. The damper near the chimney is known as the chimney-damper. When open it gives a free outlet for the escape of smoke and gas. When partially closed, as is usually the case in most ranges, except when the fire is started, it serves as a saver of heat. There is also a check, which, when open, cools the fire and saves heat, but should always be closed except when used for this purpose.
