subject: Cook Well With A Good Gas Range [print this page] A gas cooker is used normally in cooking in our day-day life. This is a cooker which uses natural gas or other flammable gases as a fuel source. The first gas cooker was developed in the early 1820's .The gas stove cooker provides sufficient heat which is used to cook our food in a very short span of time when compared to normal stove cookers. Gas stoves today use two basic types of ignition sources, standing pilot and electric. A stove cooker with a standing pilot has a small, continuously burning gas flame (called a pilot flame) under the cooking pot. The flame is between the front and back burners. When the stove is turned on, this flame lights the gas that is flowing out of the burners. The advantage of the standing system is that it is simple and completely independent of any outside power source. Early gas stoves did not have pilot. One had to light these manually with a match. If one accidentally left the gas on, gas would fill the oven and eventually the room. A small spark, such as an arc from a light switch being turned on, could ignite the gas on, triggering the violent explosion.
To prevent these types of accidents, oven gas cooker manufacturers developed and installed a safety valve in the oven. The safety valve uses a pilot flame to ignite the main burner when the oven is turned on.
Electric ignition stoves use electric sparks to ignite the surface burners. This is the clicking sound audible just before the burner actually lights. The sparks are initiated by turning the gas burner khob to a position typically labeled LITE. Once the burner lights, the knob is turned further we can modulate the flame size.
