NG biomass-based air heaters NG air heaters are designed for combustion of biomass in granular form – from wood pellets to other biomass bulk materials (fraction up to 20 mm). They guarantee environmental friendly and safe drying cycle based on clean air. The implemented technical solutions help to minimize the heating costs.
STANDARD EQUIPMENT CASING – walls made from zinc-plated steel plate and insulated with mineral wool COMBUSTION CHAMBER – made from acid-resistant steel HEAT EXCHANGER – made from acid-resistant steel and designed so as to achieve a maximum heat exchange area while maintaining minimal resistance to exhaust gases and air FAN SECTION – fan with adjustable efficiency by using an inverter PELLET BURNER – with a segmented, mobile stepped grate and ceramic insert in the combustion chamber CONTROL CABINET – microprocessor controller with stove exhaust air temperature sensor
SPECIAL FEATURES: - COST SAVINGS – drying or heating costs reduced by half in comparison to the conventional fuels such as fuel oil, liquid petroleum gas (LPG)
- HIGH THERMAL EFFICIENCY - ECOLOGY – heat exchanger provides clean air supply, pellet fuel causes no environmental pollution as a result of complete combustion, and ash is used as plant food. - CONVENIENCE – fully automated processes, no need to monitor the combustion cycle.

Biomass-based batch dryers Batch dryers are designed for drying all types of cereal grains, rapeseed, maize and sunflower. They guarantee environmental friendly and safe drying cycle based on clean air. The implemented technical solutions and the biomass-fired stove make it possible to reduce the drying costs compared to fuel oil or LPG. The batch drying process can be divided into four stages: loading, drying, cooling and unloading of grain from the batch dryer. STANDARD EQUIPMENT loading buffer segment with roof drying segments with exhaust duct extractor with mechanical speed control to collect grain from the column exhaust fans air duct (thermally insulated) in the stove biomass-fired stove with heat exchanger (pellet burner) control cabinet level sensor external ladder outlet duct and a control system

1) Loading capacity for wheat at 750 kg/m3 bulk density. The manufacturer reserves the right to make technical modifications. 2) Capacity level for rapeseed at 680 kg/m3 bulk density. - Capacity levels for the following drying temperatures: 90°C for rapeseed, 95°C for wheat, at an ambient temperature of 110 oC; 110°C for maize, at an ambient temperature of 0°C; air humidity from 35% to 70%. - Parameters without the cooling process and with the loading capacity at 30 t/h. - Dry wood pellet quantity required to dry 1 tonne of grain at 1% moisture content: about 5-7 kg (depending on the grain quality) at an ambient temperature > 0oC and with proper operation.
