Reliable, sustainable, economical Efficient concepts in the use of biomass for energy recovery In addition to companies directly involved in the timber industry, an increasing number of local authorities, contractors and other commercial energy providers are opting for biomass as a fuel. Biomass is less prone to extreme price fluctuations than fossil fuels and, being sustainable and CO2 neutral, makes a significant contribution to preserving quality of life for future generations. The type of fuel and other customerspecific requirements determine the type of combustion system. Options include...

Combustion systems

Combustion systems make the difference The type of fuel and other customer-specific requirements determine the type of combustion system. Options include flat moving grate, step grate, direct firing and special combustion systems – all of which are also available as low NOx versions to reduce nitrogen oxide emissions. Vitoflex 300-FSB Fully automatic wood combustion system with flat moving grate combustion 180 to 1700 kW For dry to moist wood fuels Moisture content: max. M50 Page 10 Vitoflex 300-SRT Fully automatic wood combustion system with step grate combustion 850 to 13,000 kW Woodchips,...

Wood combustion system with flat moving grate combustion The flat moving grate is suitable for a diverse range of wood fuels Flat moving grate combustion The flat moving grate is especially well suited for the combustion of wood fuels with a moisture content of up to 50 percent and an ash content of up to 3 percent.The Vitoflex 300-FSB is versatile in its use of fuel and produces flue gases with a low dust concentration due to its static fuel bed – both of which are major benefits. The geometry of the combustion chamber is the result of research at our own test facility, and flow simulation...

Flat moving grate combustion system with hydraulic direct feed Take advantage of these benefits Combustion chamber with multiple insulation and high grade fireclay lining Three-pass flame tube boiler or two-pass boiler with water wall with flue gas temperatures below 190 °C at full load Output: 180 to 1700 kW High efficiency of up to 92 % Version for flow temperatures above 110 °C available as an option Minimal radiation losses due to complete insulation of the entire boiler system Universal use of different types of wood fuel with moisture content between M6 and M50 Static firebed results in...

Wood combustion system with step grate Wood combustion system with step grate combustion, 850 to 13,000 kW Suitable for continuous operation The Vitoflex 300-SRT wood combustion system, with step grate combustion, is designed for continuous operation of more than 8000 hours a year. This makes it suitable for power generation in biomass CHP units. The fuel may contain up to 55 percent moisture without loss of output. These conditions enable flexible use of affordable fuels, such as woodchips from forestry work, green cuttings, bark and wood from countryside management, without the need to dry...

Vitoflex 300-SRT - wood combustion system with step grate Take advantage of these benefits ■ Three-pass flame tube boiler or two-pass boiler with water wall with flue gas temperatures below 190 °C at full load ■ Output: 850 to 13,000 kW ■ Modulation range: 25 to 100 % ■ Flue gas temperature: < 190 °C at full load ■ Combustion chamber geometry optimised to ensure the lowest possible flue gas dust concentration ■ Highly robust, thanks to low stress on components and fireclay ■ Designed for continuous operation (hours at full load per annum > 8000) ■ Step grate technology for high degree of...

Wood combustion Vitoflex 300-FSR system with flat 850 to 13,000 kW moving grate combustion Trusted technology for dry to moist fuel The major benefits of flat moving grate combustion (type FSR) are the ability to use different fuels and a low dust concentration in the flue gas, due to the static fuel bed. Low NOx reduction technology can be employed to best effect in flat moving grate combustion systems. The low NOx combustion chamber is equipped with primary-side features such as air staging to reduce NOx emissions. Standard boilers are designed for a maximum flow temperature of 100...

Vitoflex 300-FSR - wood combustion system with flat moving grate combustion Take advantage of these benefits ■ Three-pass flame tube boiler or two-pass boiler with water wall with flue gas temperatures below 190 °C at full load ■ High efficiency of up to 92 % ■ Output: 850 to 13,000 kW ■ Minimal radiation losses thanks to complete insulation of the entire boiler system ■ Static firebed results in significantly lower emissions ■ Highly wear-resistant due to generously dimensioned grate area and water cooling of grate ■ Overlapping pre-tensioned grate rods ensure little fuel falls through the...

Wood combustion system with direct firing Direct firing system with high temperature fluidised bed combustion to maximise the energy yield of wood residues from wood processing The very dry and dust-like fuel is blown through one or more feed pipes into the fully ceramic-lined, highly insulated combustion chamber. The blowing action combined with the specially developed combustion chamber geometry ensures optimal burnout of the fuel and the required turbulence and flow characteristics. The heat retention in the fireclay mass ensures correspondingly high combustion chamber temperatures, which...
