The underfeed combustion system with a double grate is particularly suitable for burning fuels containing dust, such as residues from wood processing (chipboard and MDF) and sawmill residues. The stationary fire bed ensures low pollutant emissions even when burning fluctuating or problematic fuels.
For discharging wood chips from larger stores, the hydraulic push floor discharge is ideal. This sturdy technology is greatly appreciated by customers. We distinguish between underground fuel stores and driveover moving floors.
There is almost no alternative to a horizontal discharge for discharging silos with larger diameters and / or large filling heights. This system is distinguished by its sturdy design
and fault-free operation. A silo emptying is possible as an alternative besides stoking the boiler system
The bent arm discharge enables optimum space utilisation. The discharge with two bent arms transports wood chips or pellets gently out of smaller and medium-sized silo or storage rooms. It is suitable for square and round silo bases
The silo cone discharge works in a similar way to an agitator and ensures that the usually dry fuel is refilled automatically. The effective diameter of the conical screw discharge system can be between 4 and 6 metres. Especially suitable for round silo bases.
The centre screw discharge is a simple and proven system for small yet longish rooms for discharging pellets. The inclined floor construction with transport screw guarantees quiet and gentle transport of the pellets. The conveyor system is low-maintenance and its low power consumption cannot fail to impress.
With the LogicPro V4, we are introducing a completely redesigned control system that sets new standards in user-friendliness, technological integration, and efficiency. This new generation has been specifically tailored to meet the high demands of modern biomass combustion plants—both technically and in terms of ease of use.
Three key aspects were central to the development of the LogicPro V4: modern design, maximum user-friendliness, and the
use of the latest web technology. This combination enables particularly intuitive operation and powerful control of the system. The result is an interface that provides all relevant information at a glance while flexibly adapting to individual requirements.
Up to 900 kW nominal capacity and with a maximum moisture content of fuel of M 35, electric industrial hot air blowers are available for igniting the fuel in the crucible or on the moving grate.
Optional combustion chamber camera for visual inspection of the combustion chamber via remote access.
When wood is burned, nitrogen oxides are formed from the nitrogen in the fuel. The nitrogen oxides (NOx) in the flue gas can be reduced by the SNCR process so that the legal guidelines are not exceeded.
Permitted fuel types:
180–500 kW:
500–850 kW:
Are you replacing a fossil gas or oil heating system with a renewable heating system? Benefit from attractive subsidies.
Benefit from our many years of experience and let our specialists advise you individually, without obligation and free of charge.
A solid steel structure and the use of high-quality refractory lining guarantee reliable system availability for many years.
Thanks to frequency-controlled screw conveyors, drives, and flue gas recirculation, we guarantee the lowest possible power consumption under all system load conditions.
Selecting the Right Wood-Fired Combustion Box In addition to energy demand, the type, particle size, and moisture and ash content of the fuel are the most important factors in selecting the right combustion box. However, the annual operating hours and the annual load profile are also important factors.

A sophisticated design supports the in-house mass production of this high-quality product. The use of a combined internal/external grate retort (double grate) with a separate combustion air supply ensures a wide area of application for energy-efficient biomass utilization, both in the wood industry and in other industrial sectors, as well as in residential complexes and public district heating systems. The system consists of a specially designed unit for the fully automatic combustion of dry to moist shavings and wood chips. Optionally, the combustion chamber can be supplied with low NOx reduction technology for fuels with high nitrogen content. A bottom-feed screw infeed feeds the fully fireclay-lined combustion chamber. Above it is the mounted, horizontal 3-pass fire tube and smoke tube boiler in a fully insulated design.
Various options are available for ash removal from the combustion chamber, cyclone, and electrostatic precipitator, depending on the fuel and ash content. Ash discharge can be performed jointly or separately. The ash is discharged into containers of up to 800 liters or into settling pits ranging from 5.5 to 12 m². Discharge into Big-Bags is also possible.
