Claims

[Scope of utility model registration request]

In a device in which an outer cylinder is provided outside the pulverized coal supply pipe to partition it into a secondary air passage and a tertiary air passage, and the fuel from the pulverized coal supply pipe is combusted by combustion air from the secondary and tertiary air passages, the pulverized powder An inner cylinder is provided between the charcoal supply pipe and the outer cylinder to divide the secondary air passage into an inner secondary air passage and an outer secondary air passage, and secondary and tertiary air are supplied to the tips of the outer cylinder and the inner cylinder. A pulverized powder characterized by being provided with a guide member for rectifying the flow to the outside, an unpaid frame holder at the tip of the pulverized coal supply pipe, and a flow rate adjustment mechanism for controlling the amount of air in the inner secondary air passage. Charcoal burning equipment.
