WebDrafts are produced by the rising combustion gases in the stack, flue, or by mechanical means. For example, a boiler can be put into four categories: natural, induced, balanced, and forced. Natural draft: When air or flue gases flow due to the difference in density of the hot flue gases and cooler ambient gases. http://www.chemeng.co.kr/site/bbs/board.php?bo_table=vqna&wr_id=30111
