Embodiment 1

[0031] Civil briquette: Its raw material weight ratio is composed of: base material (65% of face coal, 20% of dry coal slime, 15% of coal gangue powder) 92%, sulfur-fixing smoke suppressant (20% of sawdust carbide, 78% of lime, Manganese dioxide 2%) 8%, sulfur fixation combustion aid (including KNO 3 3Kg, NaOH 5Kg, NaOH 2 CO 3 5Kg, NaCl 5Kg, H 2 (2 100Kg), add when stirring after base material and sulfur-fixing smoke suppressant are pulverized, and the addition amount is 5‰ (excluding water weight parts).

[0032] Features: Coal calorific value is 5600kCal / kg, sulfur content is 3%, the efficiency of sulfur fixation is 83.6% after testing, calorific value is 5200kCal / kg, it takes 10 minutes to be ignited, the combustion is fierce, the center is bright, the flame height is more than 15cm, and the furnace mouth temperature is as high as Above 850 ℃, smokeless, odorless, non-irritating, less ash (because no clay is added, so the ash is less than 20%), a briquette of 160mm×80m...

Embodiment 2

[0034] The briquettes used in the catering industry: the weight ratio of raw materials consists of: base material (90% of flour coal, 5% of dry coal slime, 5% of coal gangue) 94%, sulfur-fixing smoke suppressant (40% of wheat straw powder, 55% of lime, carbon dioxide Manganese 5%) 6%, sulfur-fixed combustion aid (including KNO 3 5Kg, NaOH 3Kg, NaOH 2 CO 3 3Kg, NaCl 3Kg, starch 8Kg, H 2 (0100Kg), add when stirring after raw materials and sulfur-fixing smoke suppressant are pulverized, such as an input amount of 3‰ (excluding water weight parts).

[0035] Features: Coal calorific value is 5800kCal / kg, sulfur content is 2.7%, the efficiency of sulfur fixation is 80.4% after testing, and calorific value is 5900kCal / kg. Zhengzhou Zhongzhou four-kun secondary pressure briquette machine is used to produce 8×6×3.8mm oval Briquette, with high heat and cold strength, quick to catch fire for 10 minutes, bright burning, flame height above 15cm, furnace mouth temperature as high as ab...

Embodiment 3

[0037] Coal briquettes for boilers: Its raw material weight ratio is composed of: base material (80% of flour coal, 10% of dry coal slime, 10% of coal gangue) 97%, sulfur-fixing smoke suppressant (40% of corn straw powder, 38% of soybean straw powder %, lime 20%, ferric oxide powder 2%) 3%, sulfur-fixing combustion aid (including KNO 3 1Kg, NaOH 2Kg, NaOH 2 CO 3 2Kg, NaCl 2Kg, starch 5Kg, H 2 (2 100Kg), added when stirring after raw materials and sulfur-fixed smoke suppressant are pulverized, and the addition amount is 1‰ (excluding water weight parts).

Abstract

The invention relates to a high-efficiency energy-saving environment-friendly coal, belonging to the energy source field; the coal is formed by the following raw materials by weight part: 92-97 percent of ground masses and 3-8 percent of sulphur-fixed smoke suppressors, the raw materials are uniformly mixed and crushed to be particles with less than 3mm, the 1-5 per thousand of sulphur-fixed smoke suppressors, which do not contain water weight parts is added when the particles are stirred, the mixture is casted and molded, dried naturally and encapsulated; according to the coal requirements, the ratio is adjusted, so as to lead the coal to be used as civil honeycomb briquette, coal balls for catering industry and boilers, more than 20 percent of coal is saved, and the sulphur fixation efficiency is 75-85 percent, thereby having good economic, social and environmental benefits and having high promotion value.

Description

technical field [0001] The invention relates to a high-efficiency, energy-saving and environment-friendly briquette, which belongs to the field of energy. Background technique [0002] At present, in Zhenxiong and even the coal-producing areas of the country, traditional honeycomb coal and raw coal are widely used in life and heating. It has disadvantages such as slow combustion speed, incomplete combustion, low thermal efficiency, and high concentration of sulfur dioxide emissions. So far, nearly 30 coal-fired sulfur fixation technologies have been reported, all of which have good effects in coal-fired sulfur fixation. However, no matter how good the effect is, due to the influence of regional resource conditions and production costs, the conversion rate of its achievements is low and it is difficult to promote. Contents of the invention [0003] The object of the present invention is to provide a flammable, energy-saving and environment-friendly briquette in order to sa...
