The invention discloses a burning method for pulverized solid fuels transferred by dilute phase pneumatic in a tunnel kiln and a dilute phase pneumatic transferring system. The method is to transfer solid carbonaceous fuel powder through dilute phase pneumatic which combines positive pressure pressing-deliver type and negative pressure inhaling-deliver type, directly spray the powder into a tunnel kiln to burn, wherein the solid carbonaceous fuel powder is sulfurized three times during the transferring process. According to the invention, the structure of existing tunnel kilns is not changed,pulverized solid fuels (such coal powder, petrol coke powder etc. ) which are utilized as fuel for firing refractory material, are directly sprayed into the kiln to burn, thereby greatly increasing the utilization rate of the fuel, saving fuel cost and reducing cost for firing refractory material.
