Since LPG and WPG have significantly different Wobbe index (WI), if DME is directly supplied to the gas appliance for LPG, the calorific value (input) per unit time changes drastically, resulting in combustion and output of the gas appliance. Since the performance of the DME deteriorates, a home that wants to use the DME must purchase a new gas appliance for the DME. An object of the gas supply device of the present invention is to solve the above-mentioned problems and to be able to use DME in a conventional gas appliance for LPG.

The mixing pipe 21 is connected to the gas mixer 11, and the gas mixer 11 is connected to the household gas inlet 12. The household main gas pipe 10 is connected to the domestic gas inlet 12, and a plurality of gas pipes are branched on the downstream side thereof to connect gas appliances, respectively. The gas mixer 11 will be described in detail. The gas mixer 11 has a cylindrical mixing tank 17 with one end closed, and a closed one end of which is placed in a casing 18 filled with water.

ある。Further, the conventional LPG gas appliance is designed so that its capacity and safety can be secured against the gas species in the area A shown in FIG. That is, 18 from butane with a Wobbe index of 22170 kcal / Nm 3.
It corresponds to a propylene gas species of 500 kcal / Nm 3 . On the other hand, the Wobbe index is 12420 kc
DME, which is significantly different from al / Nm 3 , cannot be used because the capacity and safety cannot be ensured in the gas appliance for LPG. The MCP is a burning speed index.

It can be satisfactorily used even if a small amount of DME is mixed with. For example, in the gas supply device of the present embodiment, 75% propane-25% butane LPG and DME are mixed,
A gas mixture having a Wobbe index equal to 100% propane is prepared and supplied to a gas appliance for LPG. L in this case
A method of calculating the mixing ratio of PG and DME will be described.

ば良いので、[Equation 1] There is a relationship. The ratio of the flow rate of LPG flowing through the first gas pipe 3 to the flow rate of DME flowing through the second gas pipe 7 is X:
1-X, the heat value of LPG is H1, the specific gravity is d1,
If the heating value of DME is H2 and the specific gravity is d2, the Wobbe index of the mixed gas should be 19000 kca / Nm 3 ,

なわち、ガス混合器１１に導かれるＬＰＧとＤＭＥとの
流量比が０．８４９：０．１５１となる必要がある。[Equation 2] Is. Here, the specific gravity of DME, propane and butane is
Since they are 1.59, 1.52 and 2.07 respectively,
Since d1 = 1.66 and d2 = 1.59, this value and FIG.
From the values of the Wobbe index of DME and LPG in the formula (1), H1 = 25949 kca / Nm 3 , H2 = 15
Since 661 kca / Nm 3, it becomes X = 0.849 by substituting these values into the equation (2) and solving. That is, the flow rate ratio of LPG and DME guided to the gas mixer 11 needs to be 0.849: 0.151.

Is narrowed by the first orifice 14 and the second orifice 16 so that the flow passage area becomes 0.849: 0.151. The supply gas pressures of LPG and DME are set to the same pressure by the first gas governor 5 and the second gas governor 9. This supply gas pressure is, for example, 3 in this embodiment.
It is set to 30 mmH 2 O. And the mixing tank 17
The mixed gas mixed therein has a cross-sectional area of the mixing tank 17 of X cm 2 , a weight of the mixing tank 17 of Y′kg, and a weight of 20.
Let Ykg be the weight of (Y '+ Y) / Xkgf / cm
2 = {(Y ′ + Y) / X} × 10 4 mmH 2 O supplied from the withdrawal pipe 19. However, the buoyancy of the mixing tank 17 is ignored. In the present embodiment, this supply gas pressure is, for example, X = 1000 cm 2 , Y ′ = 8 kg, Y = 20 kg.
Then, the pressure is set to 280 mmH 2 O. still,
The supply gas pressure of the mixed gas of 280 mmH 2 O is the same as the supply gas pressure of the conventional LPG.

The ME and the ME are merged in the mixing pipe 21 and guided to the gas mixer 11 to be uniformly mixed, and then, through the extraction pipe 19, from the household gas outlet 12 to the main gas pipe 10 and supplied to the gas appliance. It At this time, LPG and DME are supplied to the gas mixer 11 at a ratio of 0.849: 0.151, and the gas pressure in the mixing tank 17 is 28 due to the weight 20.
Since it is set to 0 mmH 2 O, the mixed gas is 280
Supplied in mmH 2 O, its Wobbe index is 19000
kcal / Nm 3 . Since this Wobbe index falls within the area A of FIG. 2, the conventional gas appliance for LPG is
This mixed gas can be used satisfactorily. Therefore, the gas mixture for LPG can be used for a conventional gas appliance for LPG, so that the fuel cost can be saved.

The set mixing ratio of LPG and DME changes, and the gas appliance causes combustion failure. Therefore, in order to prevent such a mistake in connecting the cylinders, in the gas supply device 1 of the present embodiment, the first connection port 4 and the second connection port 8 are formed with different diameters.
Since only the LPG cylinder 2 can be connected to the first connection port 4 and only the DME cylinder 6 can be connected to the second connection port 8, erroneous connection can be prevented.
