Application of Dimethyl Ether as LPG Substitution for Household Stove

Dimethyl Ether (DME) has potency for substituting LPG for household. Indonesia is rich of the sources of DME so DME usage becomes very attractive. The experiments performed in Research and Development Center for Oil and Gas Technology LEMIGAS aimed to assess application of DME for gas cooking stoves. We tested the mixture of LPG - DME at concentrations of DME: 5%, 10%, 15%, 20%, 25%, 30%, 50% and compare with LPG as reference at 6 stoves. The parameters observed are heat consumption, fuel efficiency, and flame stability. The result is the higher DME concentration increasing heat consumption and lowering fuel efficiency.
