CONTROLLER FOR EMULSION FUEL

摘要

PROBLEM TO BE SOLVED: To reduce NOx concentration in exhaust gas to a desirable level by inputting the measured value of the NOx concentration in exhaust gas to a control means and by setting a mixing ratio of emulsion fuel based on the measured value. SOLUTION: The flow signal of heavy oil TF output by a heavy oil flowmeter 6, the flow signal of emulsion fuel (TF+TW) output by an emulsion fuel flowmeter 7 and the signal of actually measured data of NOx concentration in exhaust gas output by an exhaust gas measuring device 5 are input to an automatic controller 8. The automatic controller 8 calculates a mixing ratio of heavy oil TF to heavy oil TW of the emulsion fuel (TF+TW) and set it, which can reduce the NOx concentration in exhaust gas to a desirable level satisfying a regulation value.
