A method for producing smoke in a smoke furnace:

1. Similar to the traditional smoke generation method, when the burning substance is not completely burned or in a semi-burning state, smoke will be generated. Usually, sawdust mixed with water is added to the electric burner to make it burn incompletely and produce smoke.

2. Friction smoke: an ancient method, drilling wood for fire in ancient times. When wood is not completely burned, it will be heated to produce smoke.

The principle of dynamic heating method is similar to that of wet-heat decomposition method, but the difference is that:

The heating medium is air at 300~400℃, and the heating medium of wet-heat decomposition method is a mixture of water vapor and air.

Wood chips enter the reaction chamber under the drive of compressed air; The sawdust of wet-heat decomposition method is transported by spiral conveyor belt.

Sometimes the smoke concentration is not enough. Under the action of the blower, the smoke generated by the smoke generator enters the pressurization area, which is equipped with a steam nozzle. After the steam sprayed at high speed is mixed with flue gas, the purpose of pressurization and humidification is achieved. This is a widely cited method of smoke concentration.
