Flameless solid fuel, and preparation method and application thereof

Abstract

The invention discloses a flameless solid fuel, and a preparation method and application thereof. The flameless solid fuel is prepared from, by mass, 30-60% of a main combustion agent, 20-35% of a combustion improver, 1-5% of a flame inhibitor and 10-35% of a bonding curing agent. The fuel can be continuously and stably combusted in an oxygen-free environment, has the characteristics of high combustion heat value, low combustion speed, no black smoke, no peculiar smell, no obvious flame, no harmful residue, environmental friendliness and the like, and is simple in preparation process, low in cost and long in safe storage period.

Description

technical field [0001] The application relates to a flameless solid fuel and its preparation method and application, belonging to the technical field of solid fuel. Background technique [0002] Solid fuel has been widely used in outdoor travel, catering and other industries because of its convenient transportation, simple and safe use, and high cost performance. Obvious deficiencies, such as needing to be used in a place with abundant oxygen, low combustion calorific value, fast burning speed, short duration, high flame, poor combustion stability, and short shelf life, etc., limit its application range . In some special fields, such as high-altitude areas, low-oxygen external environment, strong wind, and deep underground oil field operations, there are situations such as lack of oxygen, humidity and water, and conventional solid fuels may fail to ignite, or The phenomenon of unsustainable combustion cannot meet the actual heating demand at all.

Problems solved by technology

[0002] Solid fuel has been widely used in outdoor travel, catering and other industries because of its convenient transportation, simple and safe use, and high cost performance. Obvious deficiencies, such as needing to be used in a place with abundant oxygen, low combustion calorific value, fast burning speed, short duration, high flame, poor combustion stability, and short shelf life, etc., limit its application range

In some special fields, such as high-altitude areas, low-oxygen external environment, strong wind, and deep underground oil field operations, there are situations such as lack of oxygen, humidity and water, and conventional solid fuels may fail to ignite, or The phenomenon that the combustion cannot be sustained can not meet the actual heating demand at all

[0003] Although, before this, there are patent reports that can be used for low oxygen, even under anaerobic conditions, sustainable and stable combustion of solid fuels, such as the solid fuel formula disclosed in the patent CN101323806A, contains a large amount of nitrogen, although by adding rich Oxygen is used to ensure the sufficiency of internal combustion, but it will still release a large amount of oxygen and nitrogen compounds that are harmful to the human body and the environment. At the same time, it can also see obvious high flames. Therefore, it is limited for use in scenes sensitive to open flames.

In addition, the solid fuel capable of anaerobic combustion reported in the patent CN1598239A, the active metal fuel is enclosed in the alloy device, and the fuel is ignited by heating the tungsten wire by turning on the power supply. The reaction principle of thermite is used, and the reaction risk is high. Complex devices are protected layer by layer, and the cost is high, resulting in low competitiveness of its products in conventional fields
