PURPOSE:To restrain the discharge of toxic substance and improve combustion efficiency by a method wherein oxygen-added emulsion fuel mixed with water, oxygen and fuel is burnt in a combustion equipment. CONSTITUTION:Added-water pressurized by a feed pump P enters into a mixer M1 through a solenoid valve in a control board 35 and a water supplying propor tional device and is mixed with oil, then, it becomes emulsion oil after remixing in a mixer M2. Emulsion combustion can obtain low NOx, dust quantity reduc tion and low O2. Further, in the case of steam atmization in a combustion furnace, the emulsion fuel enters into a silencer S through an oxygen control valve C2, the oxygen is mixed with steam through a steam control valve C3 and a pipe line 19 and is sent to the burner 30 to be burnt. The temperature of flame is increased and burning velocity is increased due to the oxygen, there fore, the amount of the air may be decreased and NOx may be reduced. |
