The invention relates to a volatile matter channel for a pot type calcining furnace. The volatile matter channel for the pot type calcining furnace comprises a material pot, a material pot upper portion volatile matter concentrated channel, a front wall and a rear wall; a front wall volatile matter vertical channel is formed inside the front wall; a fire channel smoke concentrated channel is arranged on the lower portion of the front wall; the front wall volatile matter vertical channel is directly communicated with the fire channel smoke concentrated channel from the material pot upper portion volatile matter concentrated channel; a first layer fire channel volatile matter concentrated channel, a third layer fire channel volatile matter concentrated channel and a fifth layer fire channel volatile matter concentrated channel are communicated with the front wall volatile matter vertical channel; a rear wall volatile matter vertical channel is formed inside the rear wall; a second layer fire channel volatile matter concentrated channel, a fourth layer fire channel volatile matter concentrated channel and a sixth layer fire channel volatile matter concentrated channel are communicated with the rear wall volatile matter vertical channel. The volatile matter channel for the pot type calcining furnace has the advantages of enabling redundant volatile matters in high volatile matter raw materials to be directly discharged to the fire channel smoke concentrated channel through the front wall volatile matter vertical channel, enabling energy of the redundant volatile matters after burning to be utilized by following devices and not needing return matching technology.
