Biomass kilns save money in the hop kiln

Landritherm warm air heaters are available in the power classes 150kW, 250kW, 750 kW and 2500kW. The hot air from the woodchip-fired furnaces is produced by a specifically developed high-performance air heat exchanger.

This means that the units produce emission-free hot air without any detour via water (as is usually the case) and thus operate highly efficiently and reliably. The warm air heaters are becoming increasingly popular, especially for the hop kiln. From experience, the use of biomass warm air heaters in addition to the existing oil-fired furnace offers considerable savings potential.

An average of 8,000 to 10,000 litres of heating oil can be saved annually. This corresponds to a reduction in fossil CO2 emissions of approx. 24 to 30 tons per operation. Another key to success is the ideal integration of a biomass hot air generator into the entire drying process.

Maximum savings potential unfolds when the drying system (oil oven, air distribution, control technology) is optimally matched to the additional heat available. In view of the continuing, in part very low prices for wood chips and the simultaneously uncertain price development for heating oil, the acquisition of a biomass warm air heater is an economically absolutely sensible option. Furthermore, measures to reduce CO2 emissions are also eligible for funding.

Is 65°C drying temperature a challenge?

The big difference to water-operated biomass units is the fact that our units only produce hot air without any detour via water and are therefore highly efficient. The direct route via an air heat exchanger also allows much higher outlet temperatures. Thus 65°C are realizable.
