Linka - Model 250 - 15,000 kW - Hot Water Plant for Wood Chips
Linka’s fully automated wood chips system consists of a scraper unit, which supplies a constant feed of the pre-set amount of wood chips. The system ensures a complete burnout of the wood chips and efficiencies of up to 96.7 percent.
A biomass plant based on wood chips consists of a walking floor system. A number of horizontal scraper arms moves the wood chips to a sunken auger at the end of the walking floor. This auger is monitored by a photo cell. Whenever the auger is not filled hydraulic cylinders will activate the scraper arms, and continue until the auger is refilled. From here, the wood chips are transported through an inclined auger directly to a cell lock to be fed into the combustion chamber by auger. HEB columns are moulded at the end of the walking floor, and a flat wall is build over the sunken auger.
The auger and the hydraulic cylinder mountings are also moulded. When the boiler “calls” for fuel the feed procedure is activated, i.e. the scraper unit and feeding augers will start.
The scraper unit will now provide the boiler with the appropriate amount of wood chips based on the pre-installed boiler effect. The amount of wood chips is controlled by an oxygen gauge, which constantly monitors the oxygen percentage in the flue gas. . .
