Pyrotechnic heat source

A pyrotechnic heat source, also called heat pellet, is a pyrotechnic device based on a pyrotechnic composition with a suitable igniter. Its role is to produce controlled amount of heat. Pyrotechnic heat sources are usually based on thermite-like (or sometimes delay composition-like) fuel-oxidizer compositions with slow burn rate, high production of heat at desired temperature, and low to zero production of gases. Pyrotechnic heat sources can be activated by multiple means. Electric match and percussion cap are the most common ones.
