Efficient hot blast stove system convenient to ignite

The utility model relates to an efficient hot-blast stove system convenient to ignite, which is characterized in that an ambient air pipeline leading to outside air is led out from the top of an existing hot-blast stove, and a valve is mounted on the ambient air pipeline; when the hot blast stove is ignited, compressed air is replaced by ambient air, the ambient air automatically enters the stove by means of micro negative pressure in the stove, ignition of the flame nozzle can be prevented from being blown out, the ignition stability of the hot blast stove can be improved, the sudden stop phenomenon is avoided, and therefore the production progress and efficiency are improved. The pulverized coal drying system comprises an efficient hot-blast stove system, a pulverized coal collector and a coal mill, an inert gas outlet of the pulverized coal collector is connected with a hot-blast stove, and an inert gas outlet of the hot-blast stove is connected with the coal mill. Most of inert gas discharged after the pu
