PURPOSE:To improve the heating energy in the carburation of a gas with a low calorific value and reduce the cost, by mixing the low calorie gas with a vaporized petroleum gas obtained by heat exchange between a liquefied petroleum gas and heating water running through piping. CONSTITUTION:In a multi-tube heat exchanger 1 equipped with buckles 33, 35, etc., a liquefied petroleum gas is passed through a line 3 and is sprayed by a sprayer 5. Heating water goes into the multi-tube heat exchanger 1 through a line 7 and undegoes heat exchange with the sprayed liquefied petroleum gas for vaporization of the gas before it is discharged from a line 15 via piping 9, 11, 13, etc. The low calorie gas fed from a line 17 is mixed with the vaporized petroleum gas in the multi-tube heat exchanger 1 and a mixed gas with a predetermined calorific value is sent out of the equipment from a line 21. |
