Example 3
The civil modified methanol fuel comprises the following raw materials in parts by weight: 95 parts of methanol, 5 parts of modifier and 10 parts of heat value agent.
The modifier comprises the following raw materials in parts by weight: 50 parts of isobutyl acetate, 25 parts of tert-butyl alcohol, 30 parts of butyl propionate, 25 parts of diethanolamine, 1 part of methyl tert-butyl ether, AEO41 parts and 1 part of benzotriazole.
The heat value agent comprises the following raw materials in parts by weight: 25 parts of heavy naphtha, 90 parts of fuel oil and 15 parts of methylamine alcohol solution.
The preparation of example 3 was the same as that of example 1, including the following examples, all prepared according to the method of example 1.
Second, comparison of Fuel Properties
The civil modified methanol fuels prepared in examples 1 and 3 were compared with the industrial methanol (99% by mass) used in the civil burners on the existing market, and both were used on the same type of burners, as specified in the following table:
table 1 comparative test table for energy consumption of civil modified methanol and industrial methanol
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:
TABLE 2
As can be seen from Table 2, when the example 2 is used in the operation process of the NDMC100-24L wall-supporting furnace, the concentrations of carbon monoxide and nitrogen oxide in the emission are greatly reduced, which indicates that the emission of the civil modified methanol fuel completely meets the national standard requirement in the application process, and the civil modified methanol fuel has excellent performance, particularly in the aspect of environmental protection, is good for the environment, and does not cause serious pollution to the environment.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the technical solutions, and those skilled in the art should understand that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all that should be covered by the claims of the present invention.
