Natural gas is colourless in its gaseous state; when lit, it burns with an efficient blue flame. This efficiency makes gas cookers a better buy than electrical cookers. A gas cooker can also generate instant heat, adjust the heat more accurately and cool down faster when turned off.
The natural gas burners on the top and within the oven associated with gas cooker are all operated by the control knobs. Natural gas is piped into your gas cooker through a connection on the backside. Whenever a control knob is turned on, whether for the range-top burners or for that oven, a valve regulator is opened to allow gas to flow in the jets of a burning. Ignition of the gas can be an automatic ignitor system or through a separate ignition button -- in either case, a spark is generated with an electrical circuit.
On a range-top, the spark ignites the gas, which flows underneath a burner' The flame will then be distributed by a circle of slots to the sides of the burner. A removable burner cap provides protection from food spillages. Rigid metal supports around a burner hold bakeware selection away from the flare.
In the oven, a thermostat turns on the flow of ignited gas through a jet in the lower back of the oven until the oven temperature is above the price set by the control knob, at which point the thermostat will let down the gas jet. The thermostat will re-ignite the gas jet if the oven temperature falls too low. The top region of the oven interior will always be hotter than the bottom area -- experienced chefs get advantage of this heat differential when cooking various items in the oven at the same point in time.
Broilers within the oven work much the same, but the flaming gas jets are at the top oven above the top set of shelving. When the control knob is set to Broil, only those top heating elements are ignited and not and the wonderful in the back below of the oven. In case the gas cooker comes along with a grilling section on the range-top, the gas flame emerges from the skin pores in a set of straight central pipes underneath a metal grid or gauze.
One option you will get for a gas cooker is convection cooking. A conventional oven uses simply the direct heat on the flaming gas jets to cook food. In a convection oven, a small fan within the oven distributes the heat evenly throughout the oven's volume, preparing more quickly over a conventional one. Could for cookers include wet heat in order to scorching, multiple-temperature oven-drawers, and separate ovens with individual temperature controls.
