Problems solved by technology

Therefore, for barbecue, while enriching Chinese food culture, it also causes serious pollution, and the production of charcoal consumes a lot of wood, which is not conducive to environmental protection
[0003] For general civil coal, the combustion process will produce a lot of smoke, which will also cause pollution. More importantly, the sulfur and other elements in it will produce a special smell during the combustion process, which affects the taste of the food. High value, but often not used in grilling

Embodiment 1

[0016] Put 3 parts by weight of ordinary cornstarch into 30 parts by weight of water, heat, stir until gelatinization, select 50 parts of coke powder with a particle size of 1 mm, 20 parts of charcoal powder with a particle size of 1 mm, and anthracite coal with a particle size of 2 mm 20 parts of powder, the gelatinized cornstarch milk and coke powder, anthracite powder, and charcoal powder are stirred and mixed until uniform, the mixture is sent to a coal molding machine for extrusion molding, and the shaped coal is transferred to a dryer for drying. The finished product is obtained; the fixed carbon is 89.30%, the total sulfur is 0.03%, the moisture is 3.17%, and the ash is 9.5%.

Embodiment 2

[0018] Put 2 parts by weight of pregelatinized cornstarch into 25 parts by weight of water, heat, stir until gelatinized, choose 30 parts of coke powder with a particle size of 2 mm, 10 parts of charcoal powder with a particle size of 1 mm, and a particle size of 2 mm 10 parts of anthracite coal powder, mix the gelatinized pre-gelatinized cornstarch milk and coke powder, anthracite coal powder, and charcoal powder until uniform, transfer the mixture to a coal molding machine for extrusion molding, and transfer the shaped coal to Dried in a desiccator to obtain the finished product; the fixed carbon is 89.10%, the total sulfur is 0.02%, the moisture is 3.16%, and the ash is 9.3%.

Embodiment 3

[0020] Put 6 parts by weight of tapioca starch into 50 parts by weight of water, heat, stir until gelatinization, choose 40 parts of coke powder with a particle size of 1 mm, 15 parts of charcoal powder with a particle size of 2 mm, and anthracite coal powder with a particle size of 1 mm 30 parts, the gelatinized cassava starch milk and coke powder, anthracite coal powder, and charcoal powder are stirred and mixed until uniform, the mixture is sent to a coal molding machine for extrusion molding, and the molded coal is passed to a dryer for drying to obtain Finished product; measured, its fixed carbon is 89.60%, total sulfur is 0.03%, moisture is 3.18%, and ash is 9.1%.

Abstract

The invention relates to the field of fuels, and specially relates to environmentally-friendly coal specially used for barbecue and a preparation method of the coal. The environmentally-friendly coalspecially used for the barbecue is characterized by comprising the following raw materials: by weight: 20-80 parts of coke powder, 10-40 parts of charcoal powder, 10-60 parts of anthracite culm, and 2-20 parts of a binding agent. The environmentally-friendly coal is shaped and steady, convenient for transportation, cannot cause dust pollution in transportation process, and does not generate smokeand dust in barbecue process, a heat producing value of the environmentally-friendly coal is much higher than that of charcoal, and the environmentally-friendly coal has huge economic benefits, savesenergy and protects environments, has a simple preparation process, and is suitable for industrialized production.

Description

technical field [0001] The invention relates to the field of fuels, in particular to an environment-friendly briquette special for barbecue and a preparation method thereof. Background technique [0002] Barbecue has developed into a catering industry in China. All over the country, there are barbecue restaurants operating all year round. But at present, the vast majority of barbecue heat sources are provided by charcoal. However, charcoal will produce a large amount of flue gas in both its production process and its combustion heating process. Therefore, for barbecue, while enriching Chinese food culture, it also causes serious pollution, and the production of charcoal will consume a large amount of wood, which is not conducive to environmental protection. [0003] For general civil coal, the combustion process will produce a lot of smoke, which will also cause pollution. More importantly, the sulfur and other elements in it will produce a special smell during the combus...
