Problems solved by technology

[0005] In addition, there are many small industrial boilers and heating furnaces. When using fine coal, some of the small particles of fine coal are leaked under the grate, resulting in mechanical incomplete combustion loss of more than 20%. Spherical coal can get good combustion effect

Embodiment 1

[0023] Ingredients: 10% by weight of coal tar, 10% by weight of sawdust, 10% by weight of clay, 8% by weight of sodium silicate, and the balance of fine anthracite coal powder.

[0024] Sodium silicate and water are mixed and dissolved in a ratio of 1 to 3 to form a liquid binder.

[0025] Put various solid raw materials into the inlet groove of the pulverizer, and carry out pulverization processing, the fine powder particles are 0.5-4 mm, and the maximum particle size of 5-6 mm does not exceed 20%.

[0026] All kinds of raw materials are prepared according to the quantity and ready for use.

[0027] Mix and stir the required raw materials evenly, and it is better to take the material and try to achieve the shape of the mixed material by hand. And then become the preparation of semi-finished products.

[0028] Send the prepared materials into the molding machine, and press into the mold for molding. Its compression ratio is 2 to 1.

[0029] After the mold is released and l...

Embodiment 2

[0031] Ingredients: 15% by weight of asphalt, 15% by weight of rice husk, 8% by weight of carbide slag, 8% by weight of sodium silicate, and the balance of anthracite fine coal powder.

[0032] The difference with embodiment 1 is that one small boiler is adopted, and its steam pressure is 3Kg / cm 2 , use the generated steam at 120°C as a heat source, enter the mixing container, preheat and heat, stir evenly, keep the mixing temperature at 60-70°C, and discharge the material into the mold for compression molding.

Abstract

The invention relates to a kind of environment-friendly and energy-saving coal without smoke. The ingredients of the invention include: 10-15% part (by weight) of asphalt or coal tar, 10-20% part (by weight) filings of wood or rice shell, 5-10% (by weight) of slime, acetylene sludge or fosforus parget, 8-10% (by weight) of sodium silicate and fine breezes. The invention has the advantages of advanced technology, proper combining structure, convenient drawing of materials, fine hygiene conditions, simple producing procedures, good qualities good effects of saving energies and wide practical value.

Description

Technical field: [0001] The invention relates to energy-saving technology, and in particular provides an environmentally friendly and energy-saving anthracite briquette, Background technique: [0002] Residential coal mainly refers to the fuel that is directly used in people's lives as primary energy. At present, about 80% of urban residents and 20% of farmers in China rely on coal as fuel for cooking and heating. The national civilian coal consumption is about 200 million tons. Now except for a few coal-producing areas that can meet the needs of civilian coal, the coal consumption in other cities and towns is relatively tight. [0003] Despite the gradual development of fuel gas in big cities, it can only replace part of the fuel and play a role in alleviating the shortage of civilian coal, and coal will always be the main fuel for people's lives in small and medium-sized cities and towns in my country. According to relevant statistics, the annual growth rate of civilian ...
