Description

The present invention relates to a grain dryer, and relates to a burner device for a grain dryer suitable for use in a grain joint drying facility such as a country elevator or a rice center.

Conventionally, as a relatively large grain dryer used in a grain joint drying facility such as a country elevator, a dryer main body, a hot air cave provided on one side of the dryer main body, and the hot air cave of the dryer main body are used. There is known one provided with an exhaust cavity provided on the other side surface facing the above (see Patent Documents 1 and 2).

The grain dryer is provided with a dedicated burner device for each model, and the hot air generated by the burner device is supplied to the hot air cave and flows into the inside of the dryer main body from the hot air cave to dry grains. Let me. Then, the exhaust air after the grain is dried is discharged from the exhaust wind tunnel.

By the way, in this kind of relatively large grain dryer, in which a burner device is composed of a single burner, there is a problem that fine control of the hot air temperature is difficult and improvement of fuel efficiency cannot be expected.

Therefore, a dedicated burner device having a plurality of burners is used to finely control the combustion of each burner, but such a burner device is heavy and bulky, and it is difficult to bring it to the installation site. In particular, there is a problem that the replacement work of the burner device in the existing facility is large-scale and difficult.
