A smoke generator is a device designed to produce smoke for various applications, such as testing ventilation systems, creating special effects in theater, or enhancing flavor in cooking. These generators typically use a liquid or solid material that, when heated, produces a dense smoke. Smoke generators are commonly used in fire safety training to simulate smoke conditions, allowing individuals to practice evacuation procedures. They are also popular in barbecue and smoking techniques, where they infuse food with a smoky flavor. Overall, smoke generators serve practical purposes across multiple fields.
