Abstract:Natural gas serves as an essential energy source in our daily life. Regarding the fact that the Dutch gas quality bands are expected to vary a lot because the main gas supply stream in The Netherlands changes in upcoming years. Therefore, it is very important to determine the value to pay per mega-Joule of heat generated per cubic meter of gas($euro/mJ/m^3$). The traditional measurement devices may lead to some problems such as large space occupation, low portability, and over-consumption of burning gas, for the sake of optimizing the measurement devices, the possibility for miniaturizing the gas burning meter and realize it with a fabricated chip is discussed. However, realization of steady and continuous combustion in microscale is quite different from in macro scale, some problems like flame quenching which will extinguish fire may happen in small space burning system, on the other hand, if the combustion power is beyond the limitation of which chip material can withstand, the chip may break down as well, thus this assignment mainly focuses on investigating the feasibility for creating a steady burning fire on small scale, also on the possibility of 3D printing a combustion chamber with high melting point material---aluminum oxide.
