Abstract

PURPOSE:To provide a complete combustion in a narrow gas generating chamber and prevent an occurance of soot caused by incomplete combustion by a method wherein a volume of fed combustion air is adjusted to increase more than a fed volume of liquid fuel when the liquid fuel is combusted incompletely. CONSTITUTION:When a change-over plate 11 is changed over to a winding coil contact point 12 for a normal rotation of a blower 2, a specified volume of combustion air corresponding to a feeding volume of liquid fuel is fed into a gas producing means 1, a superior mixed gas is produced to enable a continuous gasified combustion. In turn, when the change-over plate 11 is changed over to a high speed rotary winding coil contact point 13 of a blower 2, an excess amount of combustion air as compared with that of the liquid fuel is fed into the gas producing means 1 and the liquid fuel is completely combusted also in the narrow gas producing means 1.

Even if the amount of combustion air blown inside the base end 1111 of the gas generating body 1' is always constant, gas is generated at any time to enable accurate ecological firing (top vaporization combustion) of liquid fuel. An oil supply pipe 8' that can spray oil to the gas generating body 1' is centrally located in the direction of the gas generating body 1', and there is an oil spout 9 in the optical width of the oil supply pipe 8'. 10' is a spark plug for raw/combustion use.

The base end 1ft11 of the oil pipe 8' mentioned above is the main oil pipe 11'.

Once preheated, the raw/combustion is temporarily interrupted and liquid fuel is sent through the main pipe 11' and the auxiliary oil pipe 12' in an amount larger than the amount of oil sent during the raw sand/seed process. Vaporization and P baking process 5 can be performed in an appropriate state.

Reference numeral 15' designates an ignition plug for vaporization layer ignition, which is disposed near the jet 1 (216') so that the tip Fv1M is exposed.

I will briefly explain the action of Honamei.

Now, by using the vaporizer not shown in Figs. 1 to 3, even in a narrow gas or living body 1 circle, after preheating the gas generator 1 by completely heating the liquid fuel, good vaporization combustion can be achieved. When you want to continue the operation, first disconnect and connect the switching plate 11 to the high-speed rotating coil contact 13 to blow air. Then, -bit of liquid fuel is supplied from the oil pipe 8 and sprayed in the form of fine particles through the oil nozzle 9.

As a result, a certain amount of mixed gas is continuously generated while liquid fuel is being supplied together with combustion air, and good vaporization combustion is maintained.

In addition, if you want to achieve good vaporization and oxidation by simply reducing the amount of liquid fuel fed without changing the amount of air flow and perfecting the raw PZI rather than simply reducing the amount of liquid fuel fed, As shown in Fig. 4, a certain amount of combustion air is blown into the gas generator 1' by the blower 2', and at the same time, the auxiliary oil pipe 12' is cut off by the solenoid valve 14, and the liquid fuel is pumped by the fuel pump 13'. is supplied to the oil supply pipe 8' only through the main oil supply pipe 11'. When the liquid fuel is ignited, it is completely discharged under the nitrogen atmosphere.

After both the scum generator 1' and the combustion body 3 have been preheated to an appropriate vaporizing atmosphere width in this manner, the liquid fuel is subjected to ecological combustion for a period of time 11j. After a while, the solenoid valve 14' is opened, and the liquid fuel supplied from the fuel pump 13' is sent to the oil feeder 8' via the main and auxiliary oil feed pipes 11' and 12', and is sent to the gas generator from the oil nozzle 9'. At the same time, the blower is operated to blow a certain amount of combustion air into the gas generator 1'. □The supplied liquid fuel □ is increased in quantity by a lot more than the supply amount of the ecological dawn, and is preheated while being injected into the gas generating body 1 in the direction of the arrow by the combustion air.

As a result, the liquid fuel supplied together with air for combustion inside the narrow gas generating body was preheated by burning the liquid fuel inside the gas generating body, and then the liquid fuel supplied together with air for combustion inside the gas generating body. By the above preheating, the mixed gas is turned into a mixed gas, and the generated mixed gas is vaporized and burned in the gas generating body, and further preheated. 1. Ensure complete combustion of raw/combusted material in a narrow gas generation chamber.・Burning,
Due to insufficient air supply, soot adhered to the inside of the gas generator in all departments, reducing the preheating effect.1. Alternatively, gold has the effect of making it easy to start a constant vaporization combustion without reducing the generation of vaporized gas.
