The moving grate boiler unit is equipped with a flat feed grate and also suitable for combustion material with a high ash content.
The combustion material is passed into the furnace from the rear of the furnace on the flat feed grate with high-alloy casting grate bars. The grate is designed to enable a clear, uniform distribution of the primary air supplied to the various zones, thereby creating a steady, undisturbed gasification zone. The grate carriage has a hydraulic drive, so that the movement intervals can be automatically adjusted to the capacity. The complete combustion chamber is lined with fireproof material, thereby producing a high furnace temperature even in case of wet material. An additional, full-combustion stage with furnace lining is provided above the radiation cover in the combustion room, which varies according to the material.
The secondary air supplied to the combustion chamber and the full-combustion stage makes possible a stepped combustion that results in optimum combustion and a reduction in the NOX value in the exhaust gases. This results in low emission values.
The ash is transported slowly to the end of the grate and then to the automatic ash removal system. If so desired, an ash removal system can also be installed under the grate. With this system, any material that falls through the grate is transported with the grate ash directly to an ash bucket or container, by an ash screw conveyor. |

Furnace unit
Material is passed from below into the high-alloy casting combustion retort of the underfeed stoker furnace. The complete combustion chamber is lined with fireproof material, thereby producing a high furnace temperature. A radiation cover, which varies according to the material, is placed over the combustion chamber.
The primary air is passed into the combustion retort through the cast-iron bars, where a steady gasification of the combustion material commences. The secondary air that is passed into the combustion chamber leads to optimum combustion and therefore low emission. The ash is removed over a full-combustion grate. Under the full-combustion grate, there is a screw conveyor that conveys the ash directly into an ash collection box or container.
The furnace is fully flushed with primary and secondary air and combined with the highly effective insulation, there is minimum radiation. |
