WebDec 3, 2024 · There are four stages of fire development: ignition, growth, fully developed, and decay. The ignition stage is when all four elements of the fire tetrahedron coalesce, the fuels reach their ignition temperature, and the fire begins. During the growth stage, the fire increases fuel consumption and creates more heat and smoke.The fully developed … WebSince the ignition point of coal is around 300°C, there should be another ignition source to start the firing. This takes place in two stages: 1. The first stage is to use an igniter that provide an electric spark for supplying initial ignition energy to ignite small gas or LDO burners. This is like starting the fire in domestic gas burners. 2.
