Thermogenesis is simply the burning of calories to produce heat, something which naturally occurs in warm blooded organisms. Thermogenic fat burners work legitimately or purportedly so by inducing further thermogenesis and thus raising one's metabolic rate.

Fat burners work in a variety of ways. They can boost energy, help curb appetite, promote fat to be used for energy, and even increase your metabolism and core temperature so you burn more calories throughout the day. ... Fat burners can help enhance fat loss, but only if a proper diet is in place.

Thermogenics are also commonly referred to as Fat-Burners or E/C/A Stacks (The letters stand for Ephedrine, Caffeine, and Aspirin, although Aspirin is rarely used today). These substances are designed to help promote lipolysis in the body (the breaking down of body fat to be used as energy).
