Whirl layer heating

The fuel and the bed material (sand or cinder) are held together, by the addition of a medium of fluidization, e.g., air, in the floating and with it fluidisiert. The chopped up fuel particle have a big surface, thus that a good burnout can occur. The strong tumultuous current entails a very good impulse exchange and heat exchange, thus that a steady temperature rules in the whirl layer. The combustion temperature can be determined by the introduced fuel measured stream. The temperature is thus put that the education of injurious gases (CO, NOx) as low as possible. With the whirl layer heating very low embroidery oxide issues can be kept, because a relative low combustion temperature can be driven without temperature points. Low combustion temperatures have the advantage that the relatively very engaged nitrogen molecule of the combustion air dissociated by which the education is prevented by thermal NO_x. One makes a distinction in the use between a stationary and a circulating whirl layer - both systems have the same principle. However, a part of the fuel and the bed material on top from the fire space is delivered with the circulating whirl layer by the high current speeds and is put down by return below again. The achievement spectrum of a whirl layer heating read with 5 - 100 MW
