table 1 comparative test table for energy consumption of civil modified methanol and industrial methanol
Figure BDA0003014189220000051
As can be seen from table 1, the calorific values of examples 1 and 3 are significantly improved compared to the industrial methanol currently on the market for civil burners, which indicates that the modifier and the calorific value agent selected in the present invention solve the problem of low calorific value of liquid alcohol-based fuel as civil fuel. In practical application, when 10 kilograms of water at normal temperature is heated to 50 ℃, the consumption of the modified methanol fuel in the embodiment 1 is far lower than that of industrial refined methanol, and when the civil modified methanol fuel obtains the same heat, the consumption of the civil modified methanol fuel is far lower than that of the industrial methanol, so that the thermal efficiency of the modified methanol fuel is obviously improved. Meanwhile, when in use, the civil modified methanol fuel has small corrosion effect on a burner and a pipeline system, has the corrosion effect equivalent to that of the fossil fuel adopted by the existing civil burner, is suitable for long-term use, and can not cause the blockage of the burner due to corrosion. Particularly, the stability of examples 1 and 3 was very good during long-term use, and no delamination occurred during storage for more than one year.
The example 2 is used for NDMC100-24L wall-held furnace operation, and the operation process of the alcohol fuel heating water heater is detected by adopting an industry standard because the current alcohol fuel heating water heater has no executable national standard, and the detection result is as follows:
