Abstract

---

This work aims to study the effect of the equivalence ration and temperature on the updraft gasification of cereal straw. Gasification is a complex thermochemical process to convert biomass or another carbonaceous solid fuel like coal and waste to gaseous fuel. This process takes place at high temperatures (700 - 1500 °C) and in the presence of air or oxygen as a gasifying agent. The total high of gasifier is 135 cm and the internal radius is 22 cm. The air inlet nozzles were installed 52 cm from the bottom of the reactor, and the syngas outlet was installed 111 cm from the bottom. The main aspects was to analyze the influence of temperature distribution and amount of supplied air on the fuel consumption and syngas composition as well as tar formation characteristics during the gasification process. The light tar content and composition were analysed using gas chromatography coupled with mass spectrometry (GC– MS). Experimental studies have shown that the amount of air supplied does not affect the parameters of the gasification process linearly and a striking is to compare the amount of air supplied with fuel consumption and temperature to analyze the updraft gasification. The results indicate that both light and heavy tar are changing nonlinearly for different operating conditions. The obtained results indicate the possibility of using straw in thermochemical processes to produce heat and electricity in agriculture areas.
