This is probably the single biggest obstacle to many beginner bbq’rs, in fact the unfortunate thing is many start out with the cheapest smoker they can buy, and don’t understand that they have just purchased a cheap piece of equipment, loaded with design flaws. However, they are fairly easy to overcome if you understand the basics to controlling heat.

First, heat is produced by fire, whether it is wood, charcoal, or gas (we will talk about electric in a minute). A fire needs air to stay lit, right? Most of us somewhere in life have attempted the experiment of putting a candle in a jar, and watched it go out, as soon as it ran out of air.  The same applies to a smoker. We can now control the size of the fire, with the amount of air. Increase the amount of air, and you can increase the intensity of the fire (assuming you have enough fuel). Decrease the amount of air, and you reduce the intensity of the fire.

Second, you need to have somewhere for the smoke, and heated air to go. If you put an air tube in the jar with the candle, pushing air in, the candle would still eventually go out, suffocating from it’s own smoke. The same applies to a smoker, you need an escape (or vent) for the smoke and heated air.
