It should not run continuously. Typically, the fan (sometimes called a blower) will continue to run for a minute or so after the flame is out. This does not consume much energy; it does flush the residual heated air from the ducts.
Make sure the fan is set to "AUTO" on the thermostat, to ensure proper cycling.

What is Thermocouple?
In terms of security, the thermocouple is an integral component of the furnace. A little flame that burns continuously is a thermocouple. It is frequently employed in gas furnaces that have standing pilots. In order to maintain a warm tip, the thermocouple's top is placed in the flame. When the pilot flame goes out, the thermocouple automatically shuts off the gas valve in the furnace. Thermocouples are used in everyday good ,electric power generator etc you can avail thermocouple for best price at partshnc website
How does a flame rod work?
The main circuit board in your furnace sends a small ac signal to the flame rod so now you have an ac potential from the body of the furnace to the flame rod, When the flame comes on between the body of the furnace and the rod it rectifies the ac in to dc, The flame actually acts like a diode. When this dc voltage is sensed by the control board it knows there is a flame present and thus keeps the gas valve on. Hope this helps
What is technology of oil fired furnace?
An oil fired furnace works by using oil and a flame. The oil is sent through a tube to the burner area of the furnace and when the oil is ignited with a lighter, the flame can be adjusted according to how much heat is necessary.
Furnace on and off few seconds after?
check your flame sensor

Where is the furnace pilot located?
The gas furnace pilot (flame is lit all the time) is sometimes referred to as a pilot light, but no matter what you call it, its purpose is to serve as a small ignition flame for the gas burner. And when this little flame fails to operate properly or go out, it's one of the most common reasons a gas furnace will fail to operate.
Is blast furnace a batch furnace?
