Radiant and thermal
A burning candle produces thermal energy and light.
Burning typically produces thermal energy, also known as heat energy. This process involves the conversion of stored chemical energy in a material into heat and light energy as the material combusts and reacts with oxygen.
A burning candle produces light energy and heat energy through the process of combustion, where the wax and wick react with oxygen to release energy in the form of light and heat.
A bonfire produces mainly thermal energy in the form of heat and light. The burning of the wood releases stored chemical energy in the form of heat and light energy.
Burning a candle produces light and heat energy through a chemical reaction called combustion. The heat energy is a result of the candle wax and wick being oxidized by the flame, releasing energy in the form of heat and light.
The chemical energy in whatever fuel is burning.
Burning wood is the process of converting chemical energy in the fuel into thermal energy. Heat transfer is the process of moving thermal energy from one object to another. There are different types oh heat transfer including radiation, conduction and convection. Basically, the wood burning is a spontaneous process, theoretically, but in order for the process to become under way something called the activation energy must be overcome, which means that an energy of that magnitude must be applied to the wood to get it burning (oxidising). This usually comes in the form of a spark or a flame from your lighter. So once you apply that activation energy from your lighter, the wood begins to burn, and the burning of the wood itself produces heat to propagate the process. So long as there is oxygen, fuel (such as wood or octane for example) and the initial spark, then you have fire!

Thermal energy absorption
It produces kinetic energy I think?
Rockets primarily use chemical energy stored in their propellants to generate thrust through the burning of fuel and oxidizer. The combustion of these propellants produces hot gases that are expelled out of the rocket nozzle, creating a reaction force that propels the rocket forward.
