Southern Wood Energy
Froling LM KOM-H 1000, woodchip heating system
Southern Wood Energy (SWE) uses a large amount of electricity and heat during the processing of wood chip products that are supplied to a number of markets. SWE wanted an energy efficient system which would lower their costs and increase their supply capabilities of woodchip.
A Fröling LM KOM-H 1000, commercial boiler was installed, linked to a 20,000 litre Galú Classic thermal store. This is being fed to a drying plant. All of the construction was completed by our team of in-house welders and engineers; this meant we could deliver the project within a tight timeframe.
Fuel supply and chip handling.The Fröling LM1000 was chosen for its extreme versatility when it comes to fuel. This system is designed to take G100 woodchip with a moisture content up to 50%. This is possible by having the hydraulic ram stoker in combination with the hydraulic cross feeder. The chip is loaded onto the walking floor with the telehandler, from here the hydraulic system takes over to feed the boiler at the required rate of demand.
System design and installation
The system was designed to supply 1mW of heat to the drying plant, it is critical that the plant is supplied with a constant level of heat to ensure the drier is able to get the required temperature from the heat exchangers. The design of the exchangers is critical, especially when you are using biomass instead of oil or gas, as there are more criteria to fulfil to ensure the biomass system is effective and efficient.
Dunster’s effective design has improved the production of dry woodchip on the site. SWE can now also use oversize products that cannot be used in most other biomass boilers.
