Abstract

The invention discloses an alcohol-based fuel for a high-calorific-value boiler. The alcohol-based fuel comprises the following raw materials in percentage by mass: 22-30% of methanol, 3-5% of ethanol, 25-30% of diesel oil, 15-20% of naphtha, 10-15% of xylene, 10-15% of ferrocene, 0.3-0.5% of amyl nitrate and 0.4-0.8% of dimethyl carbonate. According to the invention, methanol and ethanol are usedas main fuels and main solvents, naphtha and diesel oil are added to increase the heat value, xylene and amyl nitrate are used as combustion improvers, dimethyl carbonate and ferrocene are used as stabilizers, and the alcohol-based fuel oil for the high-heat-value industrial boiler is obtained through accurate proportioning and scientific mixing; and the heat value of the product reaches 7500 kilocalories or above, daily consumption and use of a conventional boiler can be completely met, the product does not contain harmful substances, the impurity content after combustion is small, and the product belongs to high-heat-value and high-cleanness alcohol-based fuel.

Description

technical field [0001] The invention relates to the technical field of alcohol-based fuels, in particular to an alcohol-based fuel for high calorific value boilers. Background technique [0002] At present, oil resources are becoming increasingly tense and prices are rising, but the market demand is growing. As we all know, oil is a non-renewable resource and also a strategic material of the country. However, diesel oil is still used in large quantities in many industrial burners, such as ignition oil for thermal power plants and combustion oil for various boilers, etc., causing serious quality problems. The problem of excess performance: because only a small part of the performance of diesel can be used in the burner, the diesel resources are not fully utilized, forming a real waste of resources, and the cost of diesel is relatively high, which also brings great economic benefits to the enterprise pressure. [0003] Due to the shortage of petroleum resources, alcohol fuel...
