Example Embodiment

[0007] Example 1:

[0008] 150 kilograms of raw coal (Datong blended coal) is mixed with 200 kilograms of dry coal powder, 100 kilograms of grass charcoal, 250 kilograms of furnace ash, 300 kilograms of clay, mixed with water, formed, and dried to make 1 ton of briquettes. Among them, the ash is used power plant or industrial and mining enterprise waste slag, which can be used after screening and crushing. Dried coal stone powder is produced by pulverizing the dried coal stone discarded by coal sales offices or large industrial and mining enterprises. Grass charcoal can be used to put firewood or branches or bean straw or cotton stalks into the ground according to the variety and thickness (the pit can be dug into a square or circle with a depth of 1.5-2 meters and a side length of 2-3 meters. Earth-shaped pit) is ignited and sealed with soil, and it can be prepared after low-oxygen combustion for 4-5 days.

Example Embodiment

[0009] Example 2:

[0010] Take 1 ton of raw coal (Datong blended coal) mixed with 1340 kg of dry coal powder, 670 kg of grass charcoal, 1665 kg of furnace ash, 1998 kg of clay, and the others are the same as in Example 1, to obtain composite briquettes.

Example Embodiment

[0011] Example 3:

[0012] Take 1 ton of Datong blended coal, mix 1600 kg of furnace ash, 1400 kg of dry coal stone powder, 800 kg of grass charcoal, and 1900 kg of clay. The others are the same as in Example 1, and 6.7 tons of composite briquettes can be made.

Abstract

A composite briquette is made up of coal, cinder, coal gangue powder, plant ash and clay. Its advantages include easy ignition, strong firepower, long combustion time, low cost and low odour.

Description

[0001] Technical field: the present invention belongs to a kind of briquettes. Background technique: [0002] As everyone knows, existing briquettes are generally prepared from coal and clay. This kind of briquette has a low coal yield and a high price, generally 250-270 yuan / ton. Bring a certain burden to the lives of residents. In addition, in terms of quality, this kind of briquettes is difficult to ignite, slow to catch fire, has more ash after burning, and has a strong odor. Due to the difference between coal and soil, it often has a great impact on the quality of briquettes. For this reason, many urban residents simply burn Mongolian coal chunks, Datong chunks and Taixi chunks, etc., which causes a waste of national energy. Invention content: [0003] The purpose of the present invention is to address the above problems, start with reducing production costs and quality, solve the problems of high selling price and unsatisfactory combustion, and provide an economical ...
