Pyroflex FSB

Flat moving grate firing system 180 to 2600 kW

The flat moving grate firing system is parti­cu­larly suited to the combustion of wood fuels with a water content up to 55% and an ash content of 6%. Key advan­tages include the use of a variety of fuels plus a low dust content in the flue gas thanks to the resting fuel bed.

The Pyroflex FSB is charac­te­rised in parti­cular by flexible use of various wood fuels plus a low dust content in the flue gas thanks to the resting fuel bed.

Flat moving grate firing system

We generally use low-NOx reduction technology in our flat moving grate firing systems. The combustion chamber is equipped with an NOx emission reduction system on the primary side. Regulation of the primary air supply together with flue gas recir­cu­lation ensures substoi­chio­metric combustion in the reduction zone. Secondary air is injected into the oxidation zone within the ceramic-lined portion of the combustion chamber. This air injection ensures high turbu­lence and mixing with the flue gas, resulting in optimal oxidation (CO burnout) of the combustion gases. Ideal emissions values are achieved thanks to these measures.

Minimal life cycle costs

We place the utmost impor­tance on durability and a long lifespan for our systems. This is achieved by using robust system components. Solid steel construction for the biomass boiler and the use of high-quality refractory material guarantee reliable system availa­bility for many years. Minimal power consumption in all load states of the system is ensured by frequency-controlled screws, grate drives and flue gas recir­cu­lation.
