Burners for grain dryers.

In a dryer, the burner does not heat water but the air that flows through the batch. The sizing is therefore governed by the dryer's throughput, the fuel's calorific value and the power control method.

Two types of dryer

Batch dryers

Small and medium-sized farms, a small batch size, a process based on grain circulation. Once the target parameters are reached, the batch is cooled and discharged. The burner operates cyclically, so fast start-up and stable operation under variable load matter most.

Continuous-flow dryers

A large batch size, large-scale farms and the agri-food industry. The burner runs for long periods under heavy load — efficiency, reliability and the ability to modulate are what matter.

Which burner

• Natural gas or LPG — clean combustion and simple control; requires a gas connection or tank.
• Light fuel oil — where gas is not available; requires a tank and regular nozzle servicing.
• FPB process burners and hot-air generators — the manufacturer lists drying grain, milk powder and feed as one of the applications of process burners.

Data needed for sizing

• Thermal power or dryer throughput (e.g. t/h of dried grain) and the drying-air temperature.
• Dryer type and manufacturer (existing burner, chamber, duct).
• Available fuel and gas pressure.
• A photo of the nameplate of the current burner or dryer.

With this data we will put together a proposal for the model, accessories and controls. The power ranges can be found on the process burners and gas burners pages.
