Thermal energy of the order of 5 MJ is released, by flaring 1 m3 of producer gas in the burner. Flame temperatures as high as 1550 K can be obtained by optimal pre-mixing of air with gas. For applications which require thermal energy, gasifiers can be a good option as a gas generator, and retrofitted with existing devices. An appropriate site to realise the above application is an unelectrified village or hamlet. The benefits derived from this could be many, right from irrigation of fields to the supply of drinking water, and illuminating the village to supporting village industries. The other suitable sites could be saw mills and coffee plantations, where waste wood (of course of specified size) could be used as a feed stock in gasifiers.
