Gasification of the solid fuel converts its organic part into combustible by interaction with air/oxygen and steam so as to obtain a secondary gaseous fuel of high calorific value having no ash. Gasification reactions are normally carried out at about _____________ °C?
Correct answer: B. 900-1000
- A. 400-500
- B. 900-1000
- C. 1400-1500
- D. 1700-1800
Explanation
Gasification requires high temperature for the reactions of carbon with oxygen, air and steam, and is commonly conducted near 900 to 1000°C. The lower temperature range is insufficient for normal gasification.
