Why heat with wood? The rising cost of fossil fuel and growing environmental awareness are resulting in an ever-increasing demand for renewable forms of energy. Today heating with wood is an environmentally friendly and economical alternative or addition to conventional heating systems for fossil fuels. Sustainable When wood is harvested within the context of sustainable forestry, it is a renewable and environmentally friendly source of energy and an important part of sustainable resource management. CO2 neutral When wood is burned, only so much CO 2 is released as the trees have actually absorbed...

Things you need to know about wood What types of wood can be used? Wood boilers can be operated using a wide variety of wood fuels with different net caloric values, storage requirements and costs. The type of fuel chosen depends on the available storage capacity, the facility's requirements and the availability of the different fuel types. Since the fuel quality inuences the efficiency and service life of the facility, good-quality untreated wood with a low moisture content should be selected. How economical is wood heating? With a biomass system, approximately 50 percent of the total operating...

Pellets Pellets are the most compact form of wood energy and offer a high caloric value. Ensure that the pellets conform to standard branded quality (e.g. EN Plus, DIN Plus or ÖNORM). Wood shavings Untreated wood shavings are wood processing by-products from facilities such as sawmills and joinery workshops. Woodchips Woodchips are small pieces (e.g. chips) of natural wood, with or without bark. Mixed wood Untreated mixtures of woodchips and wood shavings are classied as mixed wood. Bark Bark is the term used to designate shredded bark residue. Wood dust Wood dust is the residual dust generated...

W35 100 to 540 kW Page 8 Pyrotec Fully automated wood boiler with grate combustion For pellets, woodchips and wood shavings Water content: max. W50 390 to 1250 kW Page 10 Pyroex FSB Fully automated wood boiler with at moving grate combustion For dry to moist wood fuels Water content: max. W55 180 to 1700 kW Page 12

Wood boiler with rotation combustion PYROT Innovative wood boiler with rotation combustion from 100 to 540 kW. For wood fuels with a maximum water content of 35 %. Pyrot wood boiler with rotation combustion for pellets, woodchips and wood shavings The patented rotation combustion system of the Pyrot wood boiler is state of the art. A feed screw conveyor continuously supplies wood fuel onto a moving grate, where gasication of the fuel takes place (with Lambda-regulated primary air supply). Continuous gasication takes place under air starvation. Rotary fans mix rising combustion gases with secondary...

Pyrot – wood boiler with rotation combustion Take advantage of these benets: Fully automatic wood boiler with rotation combustion Rated heating output range: 100 to 540 kW For dry wood fuels with a maximum water content of 35 % High efficiency and low emissions in output mode (up to 92 %) due to controlled primary and secondary air supply, and low particle combustion Permissible ow temperature up to 100 °C Permissible operating pressure: 3 bar Two-pass heat exchanger and modulating output control (4:1 control range) Automatic ignition prevents having to maintain the rebed and saves fuel Easy...

Wood boilers with grate combustion PYROTEC Wood boilers with state of the art grate combustion, from 390 to 1250 kW. For wood fuels with a maximum water content of 50 %. The moving infeed grate, the proven combustion retort and the sloping external grate in the Pyrotec optimally combine the benets of infeed and underfeed combustion. A feed screw conveyor transports the wood fuel into the combustion retort, where it is pre-dried. On the external grate and the moving infeed grate the fuel is completely degassed. The wood gases are then burned with the aid of a regulated secondary air supply. The...

Pyrotec wood boiler with feed screw conveyor and burn-back protection Take advantage of these benets: Firebrick-lined combustion chamber with external grate and moving infeed grate Fully automatic wood boiler with grate combustion Rated heating output range: 390 to 1250 kW Universal application for all types of wood fuel from dry (W10) to wet (W50) High efficiency thanks to proven combustion technology, three-pass heat exchanger, modulating output control and regulated primary and secondary air supply Permissible ow temperature up to 100 °C Maximum operating pressure: 6 bar Easy servicing thanks...

Wood boilers with grate combustion PYROFLEX (type FSB) The at moving grate of the Pyroex (type FSB) is suitable for a diverse range of wood fuels. Flat moving grate combustion The at moving grate is particularly suited to the combustion of wood fuels with a high ash and water content. The Pyroex (type FSB) is versatile in its use of fuel and produces ue gases with a low particulate content due to its static fuel bed – both of which are major benets. The geometry of the combustion chamber is the result of research and ow simulations. Systems with at moving grate combustion make use of low NOx...

Flat moving grate combustion system with hydraulic direct feed Take advantage of these benets: Combustion chamber with multi-layer insulation and high-grade reclay lining Wood boiler with grate combustion Rated heating output range: 180 to 1700 kW High efficiency up to 92 % Version for ow temperatures over 110 °C (available as an option) Minimal radiation losses due to insulation of the entire boiler system Universal use of different types of wood fuel with water content of W6 to W55 Static rebed results in signicantly lower emissions Highly wear-resistant due to generously dimensioned grate...
