Correct answer: D. Natural draft
- A. Forced draft fan
- B. Induced draft fan
- C. Steam ejector
- D. Natural draft

By-product coke ovens commonly use natural draft through the chimney to draw the heating-chamber flue gases through the regenerator and out of the battery. An induced-draft fan may be used in some designs, but it is not the standard answer for this general arrangement.
