Apparatus and method for separating particulate from gas produced by combustion of fossil fuel including a main vessel having a lower compartment in which the fuel is burned and an upper compartment in which the separation of particulate takes place. The separation is effected by combining roughing cyclones for separating the larger particulate with modules of cross-flow filters for separating the residual smaller particulate which emerges from the cyclones. The upper compartment includes a plurality of pressure vessels each containing a cyclone and modules of cross-flow filters mounted vertically. In each module the cross-flow filters are divided into an upper cluster, middle cluster and a bottom cluster. In each of the upper and middle clusters the cross-flow filters are arrayed or stacked vertically in columns in T configuration. In the bottom cluster the filters are arrayed in cruciform configuration. Each cluster has a separate pipe for conducting gas processed by the cross-flow filters out and pulses for cleaning the cross-flow filters in. The cleaning gas is conducted in succession through the separate pipes. The middle cluster is rotated about 120°about its vertical axis with respect to the upper cluster to afford clearance for the respective pipes from these clusters. The vertical axes of the pipes from the three clusters are spaced by 120°from each other.
