摘要： PURPOSE:To eliminate the need for a pressure pump or the like for a fuel oil and reduce the cost of equipment of a gas burner by a method wherein when an oil and a gas are burnt in a multifuel combustion manner, a combustion gas of low pressure is supplied from the center of a gas burner, and a fuel oil from the outer circumferential part of said gas nozzle. CONSTITUTION:The gas nozzle has a gas nozzle part 2 to which a gas of given pressure is introduced from a passage 4. The gas is passed through said nozzle part 2 and jetted out from a jetting end part 5. A plurality of oil nozzle parts 3 inclining so as to face to the jetting part 5 are provided around the gas nozzle part 2. A fuel oil having a given pressure passes through a plurality of passages 6 in the gas burner, reaches the oil nozzle parts 3, mixes with the gas in the jetting part 5 and then jets out from the jetting part 5 to be burnt. In the combustion method using said gas burner, a city gas, which has a relatively low pressure, or combustible gas such as LPG is employed for accelerating and stabilizing the combustion of a fuel oil. Accordingly, the need for a high-pressure oil pump or the like can be eliminated.

The concentrated bilge, increased in content of oil, is stowed in a tank 4t. Meanwhile, after waste oil produced in a ship is stowed in a tank 8t, the waste oil is emulsified to feed it to a first incinerator 6. The waste oil is sprayed by an atomizer 16 for combustion. Solid combustible substance, such as solid waste, garbage, is adjusted into proper size, and is charged in the incinerator 6 for combustion. The concentrated bilge is sprayed by the atomizer 9, heat is imparted on the bilge within a second incinerator 7 under a high temperature condition, and the bilge is increased in temperature for evaporation and is burnt.

摘要： PURPOSE:To automate the water separating operation of the waste oil tank, by detecting the amount of infrared rays transmitted through materials flowing down in a pipe and change in pulse number. CONSTITUTION:A solenoid controlled valve 5 is set to open when the waste oil tank 1 is filled and the water and oil are separated in the tank 1. Then water at the bottom part of the tank is discharged. At this time, the infrared rays are projected from a light projector 9 and transmitted through the materials flowing down in the glass pipe 8. The amount of the transmitted infrared rays and the number of pulses are different in correspondence with the materials. The differences are sequentially detected by a light receiving device 10. When the value reaches a preset value, the inclusion of the waste oil in the discharged water is detected, the solenoid controlled valve 5 is closed, and the automatic water separation is completed. It is optimum that the infrared rays projected from the infrared ray projector 9 has a wavelength of 700-900mm. and the number of pulses of 4,000-5,000/sec.

摘要： PURPOSE:To carry out stabilized combustion under ultra-low load, by a relatively large-sized boiler equipped with a plurality of burners. CONSTITUTION:When combustion is carried out under a load set using a service system circuit, a fuel oil from an oil tank 19 is passed via a strainer 20 to a pump 21 where it is pressured, then is heated by a heater 22, and after the fuel oil is passed through a strainer 23 to an oil quantity controlling valve where the quantity of the fuel oil is controlled, the fuel oil is supplied to an oil header 25, and is supplied to every burner uniformly. The air-fuel ratio is determined by a fan damper 18a attached to a fan 18 and the oil quantity controlling valve. During the service operation, a slide damper 4.9 is slid to open fully an air intake 3.8, a fan 18 with a large capacity is driven, and equipments connected with circuits C1, D1 are operated to supply fuel oil and steam, but circuits C2, D2 are closed. In case when ultra-low load combustion is carried out, the circuit C1, D1 are closed, the circuit C2, D2 are opened, and fuel oil and steam are supplied to the oil burner B only. In this case, since combustion is effected at the primary throat of the oil burner B, the air path becomes small, and complete combustion is carried out under ultra-low load.
