A blade - slot bottom grid is intended to be used for
medium power boilers when thy are transferred to coal combustion in circulating
burning layer.
Fuel combustion in burning layer at lowed temperature decreases formation
of nitrogen oxides. The grid is installed in the area of cold hopper of
a boiler. The turning blades allow to control the process of filling,
drain, to regulate the height of layer and distribution of the material
along the grid. In the process of operation, there are no stagnant areas.
The probability of grid slagging is minimal. Granulated fuel is used.
