Wood chips hot air heating
Wood chips hot air heating
Our wood chips hot air stoves are available from 150 kW to 2500 kW nominal heat power. In contrast to cord firewood hot air stoves, wood chips based hot air stoves are fully automatic. The devices are ready-to-use systems and are portable as well.
Thus, our clients are able to use the hot air stove at various locations. The integrated day tank ensures long-lasting and even heat output. From 750 kW, the fuel tank is constructed externally.
some benefits
Fuel: Wood chips
flexible: versatile in use
very efficient and CO2 neutral
Wood chips hot air heating LA150 and LA250
Our wood chip hot-air stoves in the 150 kw and 250 kw performance classes have reached a further evolutionary stage.
A comprehensive redesign of the combustion system has resulted in numerous advantages. Record breaking emission values enable the generators to be conveyed in almost all European countries without the need for additional filter systems.
The new, fully automatic fuel recognition system not only sets new standards in operating convenience, but also provides even higher efficiency and thus less maintenance intervals.
LA150 and LA250 - Both units hardly differ from each other in their external appearance.
Combustion chamber
A movable step grate operates inside the combustion chamber.
Touch control
The entire wood chips series is delivered with a state-of-the-art touch control system.
Wood chips hot air heating LA750
The LA 750 is designed for really large heating and drying ideas and offers all the intricacies of modern combustion technology. The LA 750 is in the same way equipped with all the components like the smaller types, but in this case and due to the portability and the fuel consumption, the storage tank has been transferred externally into a portable container.
Wood chips hot air heating LA2500
The LA 2500 combines the latest technology with superior heating power! The step grate firing with integrated pre-drying processes wood chips of G100, W40 quality without any problems.
With the 2500 kW, up to 100,000 Bm3/h can be continuously fed into the heating or drying process.
Operating principle
Induced draught blower
Secondary air openings
Ash discharge screw
Fly ash discharge screw conveyor
Step grate
Primary air inlet
Fill level flag
Combustion chamber
Water tank
Storage bunker
Spring agitator
discharge screw conveyor
Fire damper
Supply auger
Supply auger
Hot air outlet
Ash box
Heat exchanger cleaning
Cellular wheel sluice
Cold air fan
Cyclone separator
Flue gas-air heat exchanger
High performance air heat exchanger
The conveyor fan draws in fresh air. This is fed through the air heat exchanger. Thus, the air is warmed up and is 100% emission-free. Since there is no transition to water, very high discharge temperatures are possible.
