Embodiment 1

[0008] Mix 150 kg of raw coal (Datong mixed coal) with 200 kg of dry coal stone powder, 100 kg of grass charcoal, 250 kg of furnace ash, 300 kg of clay, mix with water, shape and dry to make 1 ton of briquettes. The furnace ash is waste slag from power plants or industrial and mining enterprises, which can be used after screening and crushing. Coal dry stone powder is made by crushing coal dry stone discarded by coal sales offices or large industrial and mining enterprises. Grass charcoal can 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 or diameter of 2-3 meters. Shaped soil pit) is sealed with soil after being ignited, and can be prepared by low-oxygen combustion for 4-5 days.

Embodiment 2

[0010] Get 1 ton of raw coal (Datong mixed coal) and mix 1340 kilograms of coal dry stone powder, 670 kilograms of grass charcoal, 1665 kilograms of furnace ash, 1998 kilograms of clay, and other is the same as embodiment 1, can make composite type briquettes.

Embodiment 3

[0012] Get 1 ton of Datong mixed coal, mix 1600 kilograms of furnace ash, 1400 kilograms of coal dry stone powder, 800 kilograms of grass charcoal and 1900 kilograms of clay, and the others are the same as in Example 1 to make 6.7 tons of composite briquettes.

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 ...
