Smoke is caused by little bits of the burning material which flake off and are carried into the air by the updraft of the flame. More smoke is produced by incomplete combustion, and combustion is helped by having access to more air. If you wanted to produce more smoke from a fire you would try to restrict its access to air such as by covering it with damp branches. To reduce the amount of smoke you would want to increase the fire's access to air, which is done by raising the fire and putting air holes underneath it. This allows it to steadily draw in fresh, cool air which allows the fuel to burn completely instead of becoming smoke particles. A similar technique can be used in the wild to make a stealthy fire. Two holes are dug and connected by an underground tunnel. A fire is built in one of the holes below the level of the ground, which prevents the flames from being seen from a distance. The other hole and tunnel allows fresh air to be drawn in near the base of the fire which again reduces the amount of smoke it produces. Answer from Phage0070 on reddit.com

In a fire, smoke and soot are the result of poor (incomplete) combustion, usually caused by a lack of air to react with the fuel. You can make a fire relatively smokeless by providing sufficient airflow to it. A "smokeless" firepit like the solo stove has the fuel placed on a slightly raised area, contained by a metal shield. The shield has lots of holes punched in the bottom, which provides a lot of air directly to the fuel and helps it all burn completely. In contrast, most firepits or campfires are basically right on the ground or in a small pit. This reduces the amount of air that can reach the fuel, as it has to flow downward, against the current of hot air coming from the fire, to reach the fuel. This causes incomplete combustion and a smoky fire. However, it also has the benefit of burning fuel more slowly, which helps you stretch a small bundle of logs for a lot longer. A "smokeless" firepit will burn cleaner and faster, which means you'll need a lot more fuel to feed a fire of the same size as a campfire for the same duration.

How Do Smokeless Fire Pits Work?
September 20, 2024 - A smokeless fire pit consumes most of its own smoke. Air inlets and outlets in the pit allow cooler air to enter at the top of the fire, which creates a secondary burn in addition to the flames from the burning wood inside the pit.

December 19, 2024This “smokeless” fire pit uses convection currents to pull smoke down and up again where it is actually burned again.
They do claim this, but it's not really what's going on. What they actually do is use convection to blow fresh air right where it's most useful. The key is that material can only burn in the presence of oxygen, because fire is a chemical reaction where carbon leaves whatever molecule it's bound up with and instead joins with oxygen to make CO2. These stoves pull in extra fresh air from the ground through the holes at the bottom. This air is directed to both the base of the fire, and also towards top (the inner holes on top). The oxygen simply allows hot, uncombusted material (e.g. smoke) to ignite. More on reddit.com
