슬러지 촤 마이크로웨이브 CO₂ 가스화와 순산소-스팀 연소

다국어 초록 (Multilingual Abstract)

The studies on carbon dioxide microwave conversion for sewage sludge were carried out in order to secure a biomass waste to energy conversion technology.
The microwave reforming was applied a biomass char as a carbon receptor. The carbon dioxide (CO₂), which is a main greenhouse gas, was converted to carbon monoxide (CO) fuel by the microwave reforming with fixed carbon among the carbon acceptors. The maximum CO₂ conversion rate was 74%.
In order to use the biomass char as a pulverized carbonized fuel, an oxyfuel-steam combustion technique was applied. Numerical calculations were carried out for changes in the amount of oxygen or steam feed to determine the combustion characteristics.
As the amount of oxygen feed was increased, the combustion temperature remained constant after showing the initial temperature increase rapidly. Residual char and carbon monoxide also increased in relative good combustion, and then they were extinguished and decreased respectively after the initial productions. When the amount of steam feed was increased, the temperature increase rate and the maximum temperature were relatively low, and the residual char and carbon monoxide were reduced to the latter half and then decreased respectively.
