Wood Chip and Pellet Boilers

Heating with wood chips and pellets For more than 50 years, Froling has specialised in the efficient use of wood as a source of energy. Today the name Froling stands for modern biomass heating technology. Froling firewood, wood chip and pellet boilers are successfully in operation all over Europe. All of our products are manufactured in our factories in Austria and Germany. Froling’s extensive service network ensures that we can handle all inquires quickly. Fuels: wood chips and pellets Wood chips are a local and environmentally-friendly fuel, which is not subject to the crises and...

Convenient, long-lasting, economical and safe: The TX boiler from Froling meets all your needs. This boiler is suitable for burning both wood chips and pellets thanks to its fully automatic smart operating system. Due to the well-planned and compact design the boiler needs very little space. Froling also offers a wide range of fuel feeder systems for almost all requirements. The tried-and-tested engineering systems ensure an optimum energy consumption.

High demands - smart solutions

Ventilated step grate for pre-drying of materials and optimum combustion. Tilted combustion grate to ensure full burn-out and grate cleaning during operation. Heat-resistant ash removal screw between combustion chamber and ash can. Top quality high-temperature combustion chamber with firebrick lining for very low emissions and an effective combustion at a high efficiency. Vertical 4-pass tubular heat exchanger with Efficiency Optimisation System (EOS) and with automatically actuated turbulators to clean the flue gas path in the boiler. Fully insulated to minimize radiant heat loss. H 3200...

A well-designed insideFeature: ventilated step grate Advantages: • pre-drying of fuel • ideal combustion conditions The ventilated step grate helps to pre-dry the fuel, ensuring an optimum combustion of wood chips or pellets. The step grate distributes the fuel evenly in the combustion zone, which creates ideal combustion conditions. Feature: high-temperature fireclay-lined combustion chamber Advantages: • optimum emission values • economical fuel consumption The combustion chamber provides optimal burning conditions as its made of high quality heat resistant fireclay components. The...

TX Feature: vertical 4-pass heat exchanger with automatic cleaning (EOS) Advantages: • high efficiency • automatic cleaning of heating surfaces The 4-pass design of the heat exchanger directs the path of the flue gases multiple times inside the boiler, ensuring efficient ash separation. The design also supports dust separation. The EOS (Efficiency Optimisation System), which comes as standard, consists of special turbulators, which are placed in the heat exchanger pipes and allow automatic cleaning of the heating surfaces. An additional benefit: clean heating surfaces ensure a...

Convenience with maximum safety 1 Sturdy agitator head (spring blade or articulated arm) 7 Sturdy stoker screw for reliable fuel feed with Maintenance-free agitator gearbox. Strong spring piles ensure even filling of the feed screw. Screw channel with progressive screw blade for smooth operation. 10 Easy access to the shear edge through an Ball joint for continuously adjustable inclination of the discharge screw to the stoker unit. 11 Monitored drop box cover. Burn-back flap or patented twin-chamber rotary valve for outstanding burn-back protection. automatic turn control. 8 Energy-saving...

Feature: patented twin-chamber rotary valve Advantages: • continuous flow of material • top burn-back protection • suitable for wood chips up to P45A (previously G50) or pellets The patented twin-chamber rotary valve offers maximum operating safety. The advanced system design with two spacious chambers ensures that the fuel is transported continuously to the combustion zone. This optimal fuel metering ensures the best possible combustion values. The two large chambers are especially suitable for transporting wood chips up to P45A (previously G50). The high-quality cutting edges can be...

Spring blade agitator (SBA) Suitable for discharge of wood chips from bunkers with a maximum working diameter of 5 metres. The system is maintenance-free and especially designed for easily pourable fuels (wood chips P16A/P45A to M35 previously G30/G50 to W35). The simple and effective design of the feed system ensures smooth operation. Any problematic materials (e.g. foreign bodies) in the fuel are automatically detected and removed by a reverse turn of the screws (turn control). The feed screw (diameter 150 mm) with progressive pitch guarantees low energy consumption. Screw channel The...

For discharge of wood chips from bunkers with a maximum working diameter of 6 metres. The system is low-maintenance and is especially designed for fuels with increased discharged output due to their limited ability to flow. The patented design guarantees quiet and effective operation. Any problematic materials (e.g. foreign bodies) in the fuel are automatically detected and removed by a reverse turn of the screws (turn control). The feed screw (diameter 150 mm) with progressive screw blade ensures low energy consumption. The joints are strengthened with torsion springs. The spring...

Bunker filling systems Vertical feed screw Bunker filling screw The vertical feed screw sets a new standard for feed output (45 m³/h), operating safety and bunker filling. The tipping gutter pushes the wood chips into the vertical feed system, which transports the fuel to the desired height for the centrifugal disc. Even distribution of the fuel is guaranteed as the vertical feed screw enables dust free filling of the fuel store. The bunker filling screw transports the fuel reliably into the fuel store and stops automatically when the bunker is full. The fuel is transported using the bunker...

Filling at ground level Filling from above The boiler room is on the same level as the storage room which can be an inexpensive addition. The fuel store can be filled easily using a front loader or similar through the large store door. The storage room is outside under the access level. The fuel is tipped into the store from above. It again can be an inexpensive addition. The storage room is above the boiler room. Fuel is fed to the boiler through a downpipe. The use of a rotary valve is highly recommended. The storage room can be filled conveniently using the vertical feed screw or...
