Q. In a furnace employing forced draught compared to induced draught (Solved)
1. the fan operates hot and hence blades are liable to corrosion and erosion
2. positive pressure exists in the furnace
3. air is sucked in, so air leaks are more and hence furnace efficiency is reduced
4. none of the mentioned
- c. air is sucked in, so air leaks are more and hence furnace efficiency is reduced
