Gas stove

A gas stove is a kitchen large equipment (see see cooker ) which serves the heating of foods. Gas stoves are available with or without integrated oven ( also heated with gas or electric).

Description

The gas supply to the cooker can be done from the town gas or natural gas grid via a gas outlet or with liquid gas from the gas cylinder.

During operation of the gas stove for a produces heat but causes additional moisture to occur as the reaction product of the combustion gas to both carbon dioxide and water. This effect is particularly easy to observe in gas ovens with viewing window: there condensate is formed, until the surfaces of the interior have as much heated that no more moisture condenses.

Today, gas stoves are equipped with a device for flame monitoring, such as a thermocouple. This is to prevent that unburned gas leaks accidentally.

Modern gas hobs have compared to electric stoves most economically and with redundant safety precautions. Some versions have a hob glass ceramic, have a fully electronic ignition and may have low temperatures of 75 ° C in the oven by clocking realize. Since ordinary gas ovens can not provide temperatures below 150 ° C, even combination devices are distributed, which allow gas cooking and baking power.

A special form of the gas cooker is the direct -heating burner stove China (or Wok range ) in Asian cuisine.

Advantages of gas oven

• Very quick regulation of heat within seconds
• Lower energy costs ( one kWh of natural gas costs only about 30 percent of one kWh of electric current )
• Most environmentally friendly than current
• It can also cost pots and pans can be used with uneven floors
• Use is also in areas without power supply or power failure problem (if the gas cooker is not dependent to ignite the flame on AC power )
• Larger heat than most electric Bratrohren / Ovens
• Use of a traditionally shaped woks possible

Disadvantages of gas oven

• Combustion and fire hazard of open flames
• Accident hazards involving a higher risk to the environment if improperly handled
• Most cooking pot handles get very hot by the hot air / gases flowing past the side of the pot, plastic handles can also be deformed or cause considerable stench. Incorrect operation ( small pot, large fire pit ) is a burning of the plastic parts possible. Saucepans with metal handles are therefore useful.
• Low temperatures (below 150 ° C) can not be set in an oven usually. Braising or keeping warm is thus limited. Newer models, which often also have a ceramic hob, can also realize a lower temperature accurately by electronic ignition and timing, but pay for the advantage of the rapid regulation a.
• High heat losses by convection and radiation
• Adequate ventilation of the space needed
• In the open type (without glass plate ) more difficult than cleaning the electric stove

Operation with LPG

For operation with a propane gas bottle (via pressure regulator for 50 or 30 mbar) no official permission is required, unless the stove has a power output of less than 11 kW and the room has more than 20 m³ volume and located on the ground in Germany. A 11- kg gas bottle must be located in the room. For use with propane gas, the burner nozzles must be replaced as a rule, as these are usually set at the factory for natural gas.
