Claim 12:
13. A system comprising,
a nozzle;
a dosing line connected to the nozzle and a fuel dosing module;
the fuel dosing module in fluid communication with the dosing line, the fuel dosing module comprising:
an outlet in fluid communication with the dosing line;
an air inlet positioned upstream of the outlet, the air inlet configured to receive air;
a fuel inlet positioned upstream of the outlet, the fuel inlet configured to receive fuel; and
a fuel valve positioned upstream of the outlet and downstream of the fuel inlet, the fuel valve configured to control a flow of fuel, wherein the fuel dosing module is configured to combine the fuel and the air upstream of the outlet and downstream of the fuel inlet to generate an air-fuel fluid, wherein the air-fuel fluid removes particles from the nozzle;
a fuel shutoff valve positioned upstream of the fuel valve;
an air flow valve downstream of the air inlet and upstream of the fuel valve, the air flow valve configured to control air flow from the air inlet into the fuel valve; and
an air bypass line downstream of the air inlet and upstream of the outlet, the air bypass line configured to direct the air to the outlet and bypass the fuel valve.
