STRUCTURE OF WOODEN BIOMASS BURNING HOT AIR HEATER AND CONTROL METHOD

Japanese Patent JP2016223758

A

PROBLEM TO BE SOLVED: To enable a labor saving for a work to remove combustion ash accumulated inside a combustion chamber and a heat exchanger to be attained, an establishment of a high heat exchanging efficiency of a hot air blower to be accomplished and a longer hour maintenance to be realized.SOLUTION: A cyclone acting as a dust collector is made small in size as a multi-cyclone 8, mounted between an outlet of a combustion chamber and an inlet of a heat exchanger 14, ash accumulated inside the heat exchanger 14 is reduced and a heat transfer efficiency of the heat exchanger 14 is increased. Ash accumulated in a combustion chamber 6 is flowed and removed at the multi-cyclone 8 at a downstream side by blowing heated air regularly with a blow fan 11 constituting a double fan. An ash storage 15 at the lower part of the multi-cyclone is connected and the ash can be scraped by a screw type ash discharging machine 13 even if the hot air is being operated. With this arrangement as above, the ash accumulated in the hot air device is decreased and not only a heat efficiency is increased, but also a repetition time of operation stopping through ash discharging work is decreased and its labor saving can be attained.SELECTED DRAWING: Figure 1
