USING LIQUIFIED GAS MIXING FUEL AND ITS SUPPLY SYSTEMS FOR SEMI-PREMIXED COMBUSTION OF LIQUIFIED FUELED COMBUSTION EQUIPMENTS

摘要

PURPOSE: A mixed fuel of liquefied gases for pre-mixed combustions of liquid fuel injection combustions and a mixed fuel supply system is provided to solve a reduction of the thermal efficiency and reduce costs by minimizing after-treatment devices because a rest mixed fuel is separated into diesel fuel and a gas fuel and re-circulated after injecting. CONSTITUTION: A mixed fuel of liquefied gases for pre-mixed combustions of liquid fuel injection combustions and mixed fuels supply system comprises an injection pump, a mixing device and a combustion chamber. The mixed fuels are provided to the combustion chamber. The mixed fuel is mixed with liquid fuels and liquefied gas fuels. The mixing device is installed right in front of the injection pump. After injecting, the rest of mixed fuels are separated into diesel fuels and gas fuels from a separator and re-circulated. The fuel oil and the liquefied gas fuels are mixed in the mixing device. The mixed fuel is supplied to a burner.
