The utility model relates to a double-step jet-flow radiation radiator of an air preheating furnace, particularly a double-step jet-flow radiation radiator of an air preheating furnace used for igniting and sintering of the blast furnace gas, which comprises a furnace shell (1) of the air preheating furnace, a radiation panel (2) and airflow channels, wherein, the radiation panel (2) is positioned in the furnace shell (1) of the air preheating furnace, and a plurality of airflow channels are arranged on the radiation panel (2). The airflow channels are divided into the large airflow channel (3) and the small airflow channel (4) according to the size of the diameter of the channel, wherein, the large airflow channel and the small airflow channel are alternatively arranged on the radiation panel (2). Because the airflow channels are divided into the large airflow channel and the small airflow channel according to the size of the diameter of the channel, and the large airflow channel and the small airflow channel are alternatively arranged on the radiation panel, the utility model avoids that the oxide skin of the metal plate falls off and blocks the airflow channel of the radiation panel because of the heating of the radiation panel, and guarantees the favorable sintering production. The utility model has the characteristics that the structure is reasonable, and the utility model avoids blocking the airflow channel of the radiation panel and guarantees the sintering production.
