Problems solved by technology

In addition, auxiliary materials such as sulfur-fixing agents, waterproofing agents, and consolidation agents are added for production. These methods consume too much energy, but the heat is not high, and the fire is too slow when burning; and the current mainstream briquette products all use coal slime. Coal slime is precipitated during the cleaning process of raw coal, which contains a large amount of impurities (ie, ash). The quality of the products is unstable, the heat is also unstable, the pollution emitted is large, and the harm to the environment still exists.

Embodiment 10-15

[0072] A kind of fly ash type fire brick, the weight percent of its each component is shown in the following table:

[0073]

[0074] The coal-burning combustion aid contains an oxidant that provides an oxygen source, which can decompose oxygen under high temperature conditions to promote the complete combustion of coal. In addition, the catalyst without corrosive substances can effectively reduce the dissociation energy of oxygen and the activation energy required for carbon combustion, strengthen the combustion of coal, and play a strong role in supporting combustion, increasing energy, and saving coal. By adding a small amount of additives to these mixtures to promote the complete combustion of coal, it can not only reduce the heat loss of incomplete combustion, but also reduce the emission of soot. Under the same volume, its combustion time is 1.6-2.2 times that of traditional briquette, and its average heat mass is 4590 kcal, which is about 40-50% higher than that of t...

Abstract

The invention relates to a coal ash type fire enhancing brick which is prepared from coal ash, coal slime, briquette coal blocks, solid fuel and coal powder. The coal ash type fire enhancing brick can improve the heat value of fuel and is good in environmental protection performance.

Description

technical field [0001] The application belongs to the technical field of reusing fly ash, in particular to a fly ash type fire brick. Background technique [0002] Fly ash is the fine ash collected from the flue gas with coal as fuel, and its content accounts for about 5% to 20% of the total coal combustion. It is the main solid waste discharged from coal-fired power plants. my country's coal-fired power plants emit more than 10 million tons of fly ash every year, and with the development of the power industry, the annual discharge of fly ash is increasing, polluting the environment, wasting resources, and occupying fields. [0003] At present, there are many technologies for producing coal briquettes, among which anthracite, mixed coal, coke powder, fly ash, biological raw materials (plant straw, sawdust, etc.), furfural, coal gangue, coal slime, etc. are used as the main raw materials. In addition, auxiliary materials such as sulfur-fixing agents, waterproofing agents, an...
