Embodiment 1

[0055] Embodiment 1: preparation coal combustion-supporting additive

[0056] 30kg of saltpeter, 10kg of marble, 10kg of talc, 10kg of feldspar,

[0057] 10 kg of pyroxene, 20 kg of pyrolusite.

[0058] Grind each of the above-mentioned ores separately to 80-120 mesh, then add them to the ball mill according to the above ratio, add water until it is wet, grind (ball mill) for 8 hours, carry out at normal temperature and normal pressure, and the speed of the ball mill is 500 rpm / min, that is to obtain coal combustion-supporting additives with particle sizes ranging from microns to nanometers.

Embodiment 2

[0059] Embodiment 2: preparation coal combustion-supporting additive

[0060] 80 kg of saltpeter, 150 kg of marble, 150 kg of talc, 130 kg of feldspar, 150 kg of pyroxene, and 30 kg of pyrolusite.

[0061] Above-mentioned each ore is pulverized separately to 150-200 order, then joins in the ball mill according to above-mentioned ratio, it is advisable to add water to wet (the amount of water is 3-5% of ore gross weight), pulverize (ball mill) 10 hours, in It is carried out under normal temperature and normal pressure, and the rotational speed of the ball mill is 600 revolutions per minute, that is, the coal combustion-supporting additive with a particle size of micron to nanometer is obtained.

Embodiment 3

[0062] Embodiment 3: preparation coal combustion-supporting additive

[0063] 50 kg of saltpeter, 120 kg of marble, 110 kg of talc, 120 kg of feldspar, 120 kg of pyroxene, and 15 kg of pyrolusite.

[0064] Grind each of the above-mentioned ores separately to 100-150 mesh, then add them to the ball mill according to the above ratio, add water until it is wet, grind (ball mill) for 7.5 hours, and carry out at normal temperature and pressure, and the speed of the ball mill is 400 rpm / min, that is to obtain coal combustion-supporting additives with particle sizes ranging from microns to nanometers.

Abstract

The invention discloses a nanometer ore coal combustion-supporting additive, a preparation method thereof and application of the additive as renewable energy source of coal. The additive comprises the following raw material ores: 2 to 25 weight portions of saltpeter, 5 to 25 weight portions of marble, 5 to 25 weight portions of talcum, 5 to 20 weight portions of feldspar, 5 to 25 weight portions of picrite, and 1 to 10 weight portions of pyrolusite. The ores are subject to ultrafine grinding and are prepared into a coal combustion-supporting agent according to certain mixture ratio, and then the combustion-supporting agent is prepared into complex coal with coal gangue and coal according to the mixture ratio. The additive can ensure that 30 to 50 percent of standard coal is saved in the power generation industry and the cement industry, can reduce the discharge amount of sulfur dioxide and smoke dust, also reduce the environmental pollution of the coal gangue caused by land occupation spontaneous combustion at the same time, has good social benefit and economical benefit, meets the requirements of energy conservation, environmental protection and emission reduction, and is worthy to be promoted.

Description

technical field [0001] The invention relates to a coal combustion-supporting additive and its preparation method and application, more particularly to a nano-ore coal combustion-supporting additive composed of natural ore, its preparation method and its application as a coal renewable energy source. Background technique [0002] At present, all countries in the world are paying attention to energy conservation, and our country is also very concerned about energy conservation and the development and utilization of new energy sources. Finding new renewable energy sources and reducing environmental pollution are the current top priorities. [0003] Industrial coal is a large energy consumer and the main source of sulfur dioxide emissions to pollute the air. Currently, coal additives on the market have a good single effect, but the overall effect is poor. [0004] Chinese invention patent application No. 95115467.2 discloses a "coal additive", which is simply mixed with potassiu...
