A protective spark eliminating system for removing burning particulates from flue gases prior to introducing the gases into a filter baghouse. The protective system includes a housing enclosing a separating chamber having a gas inlet in the side of the housing for directing a stream of flue gases into the housing, and a gas outlet in the top of the housing for conducting the flue gas stream out of the chamber. To effect separation and removal of the burning particulates from the gas stream, the housing is provided with a secondary gas system which is adapted to maintain a downwardly flowing curtain of gas across the width of the flue gas inlet to direct the burning particulates in the flue gases downwardly into a hopper at the base of the housing as the flue gases enter the chamber. Then, as the flue gas stream flows through the chamber and out of the housing to the baghouse, the particulates are drawn out of the hopper in a secondary gas stream which is directed through an inertial separator to remove the particulates and circulated back to the housing where it is injected across the width of the flue gas inlet to maintain the process.
