Status of biomass gasification

Kaasutuksen kannattavuus ja toteutustapa on ollut tarkea ja useiden tutkimuksien kohde. Biomassan kaasutuksen ja siina kaytettavien laitteiden nykytila on epavarma. Niinpa lisatutkimukselle ja tarkasteluille on edelleen tarvetta. Tama tyo keskittyy nykyisin kaytettavien kaasutusprosessien ja laitteiden tarkasteluun. Tyossa kaydaan lapi useita uusimpia kaasutusprojekteja ja esitetaan niista tutkimustarpeita. Lisaksi kaasutusprosessissa pitaa saada hallintaan niille tyypillisia ongelmia kuten kaasun puhdistus, kaasun kasittely, biomassan kasittely ja kaasuttimen muuraus, joista esitetaan lisatietoa. Edelleen esitetaan kaasutusprosessien taydellinen luokittelu. On huomattava etta biomassan kaasutusta tarvitaan jotta saadaan toteutettua EUn hahmotteleman ja saataman energiapolitiikan vaatima kasvu ja kehitys.

The problem concerning feasibility and cost-efficiency of today’s gasification technologies has been subjected to a number of research works. However, the status of biomass gasification and the systems as well as equipment used for gasifying purposes are not certain. So further investigation and observation on the gasification ought to be made. The paper is focused on an overview of currently exploited gasification methods as well as types of gasifiers. Several modern projects and research propositions are presented in the study. In addition, the gasification process is more prone to the challenges such as gas cleaning, conditioning process, biomass handling and gasifier refractory lining which are described in detail. Furthermore, full classification of different constructions with respect to gasifiers is considered. In conclusion, the biomass gasification tends to reach possible opportunities for future expansion and development as it has been reported in EU policies and legislation.
