| description | This research initially presents an internal structure optimization technique through numerical investigation with the intention of addressing the issues of unstable and poorly adjustable combustion flame of porous media methanol furnace. The entire premixed combustion technology and the flue gas waste heat evaporation technology are then combined in a combustion technology that is based on this stove structure. As a result, this resolves substantially the issues with methanol stove tempering, misfire, and uneven temperature. The fully premixed methanol cooker was eventually created and put into wide production. According to the findings, the flow rate was between 0.25 and 0.7 m/s before the cooker structural improvement and around 0.45 m/s after. More crucially, by eliminating the low temperature zone of approximately 300 °C and raising the temperature to about 500 °C, the temperature field at the cooker's exit porous medium was much improved. Additionally, the methanol cooker in the typical diffusion combustion mode was outperformed by the full premixed combustion technology and flue gas waste heat evaporation technology in this trial in terms of complete fuel combustion with no pollutant emissions. The study's findings indicate that the cooker's overall thermal efficiency is 68.2%, which has clear financial benefits. |
