Stoves

Stove can be defined as an apparatus in which fuel is used to furnish heats for cooking or warmth. The word stove first referred not to a cooking or heating device but to a room for taking a hot-air or steam bath (first recorded in 1456). During 1550 and 1625, the devices used to heat rooms came to be called stoves. The stove as the chief cooking device, taking the place of the fireplace, dates only to around the mid-19th century with the widespread use of wood or coal burning cooking stoves. An improved stove is a complex engineering device involving closely coupled phenomena like pyrolysis, combustion, fluid flow and heat transfer. The complex coupling between these makes the problem highly non-linear and hence difficult to tackle in totality.

Open Fire

OpenFire are the earliest type of cooking stoves. They are made by arranging three bricks or stones (or another forum of tripod) on the level ground approximately 120 degree to each other. This is the most primitive cooking arrangement. The fuel used is generally firewood the size of which depends on the height of the stones or bricks.

Traditional Stoves

Due to many disadvantages of open fires gradual improvements were made to the open fire cooking and evolution of cookstoves took place. The most simple one of which is the horse - shoe shaped single pot cookstove that is traditionally used in the villages of India and other countries.

Traditional Cooking Devices

Traditional Cooking Devices are very wasteful. They use only 10% of the total heating potential of the fuel burnt in them. Another disadvantage of the traditional cook stove is that they produce a lot of smoke, soot and un-burnt volatile organic matter, which not only blacken the pots and the walls of the kitchen, but also pollute the indoor air and adversely affect the health of the householders. Housewives and infants are affected the most by these pollutants, because they are maximally exposed to the flue gases.

Improved CookStove

The Improved CookStove has emerged as part of the response to the above mentioned problems and improvement in quality of life for the rural population. Improved Stove aims to save cooking time (increasing efficiency), as well as, to create a smokeless environment in the kitchen and/or reduce the volume of smoke emission. Better stove designs gradually came about during the mid-1980s. The newest designs took into consideration the complex interaction between the different processes that take place in a cookstove, such as: combustion, heat transfer fluid flow and material science. A large number of improved stove models, have been developed during the last 10-15 years.

Stove Testing

The Stove Testing The "stove problem solutions" quoted in the first article from the ITDG "Practitioner's Manual" will help field workers to follow a planned procedure for fixing a faulty stove. However, they may still need to check to know whether they have been completely successful or whether the stove still needs treatment to bring it to its full potential. Its performance can be compared with other stoves of the same kind, tested at the same time, with standard figures for the stove, or with the results of tests carried out on the stove before "fixing". This can be done by using the simple Boiling Water Test .

Stove Dangers

The dangers associated with cookstoves. The most common health and safety risk factor is minor and major burns however fire can spread and where houses are made from combustible material it is easy, particularly in dry seasons, for fires to get out of control See Stove accidents for more information.
