The conclusion of three burning methods mentioned above during the heat storage period is that the first method is the best one, which is propitious to keep higher blast temperature because of the heat exchange in the middle and blow of hot blast stove has been aggrandized through convection heat transfer caused by the added exhausted air quantity and increased flow rate.

以上三种燃烧制度，在蓄热期：第1种因废气量增大，流速加快，利于对流传热，强化了热风炉中下部的热交换，利于维持较高风温，第2种因废气量减少，不利于传热和热交换的强化，不利于维持较高风温，第3种由于废气大量减少，流速降低，传热减缓，蓄热量较少，不利于提高风温。
