Honeycomb briquette

Abstract

The invention relates to the technical field of coal industries, in particular to a honeycomb briquette; the honeycomb briquette comprises a raw coal, clay and an additive; the additive includes the components of the following weight portions: 3 to 9 of sodium chloride, 2 to 6 of alumina, 2 to 6 of ferriferrous oxide, and 2 to 6 of potassium chloride; the honeycomb briquette uses sodium chloride, alumina, ferriferrous oxide and potassium chloride as additives; due to a plurality of subtle reactions of the additives during the combustion process, the honeycomb briquette is characterized by easy combustion, long combustion time and the like; particularly, the effect is the best when the weight portions of sodium chloride, alumina, ferriferrous oxide and potassium chloride are 3:2:2:2; due to the use of the additives, the usage of the clay can be enlarged without impacting on the combustion effectiveness, and the production cost can be greatly reduced.

Description

technical field

[0001] The invention relates to the technical field of coal industry, in particular to honeycomb coal. Background technique

[0002] Honeycomb coal is a low-cost domestic fuel, widely used among residents due to its low cost of use. The traditional briquette is formed by mixing raw coal and clay with water. The clay mainly plays a role in shaping. The ratio of raw coal to clay is usually about 1:0.3. The traditional briquette has disadvantages such as not easy to catch fire and short burning time. The price of briquette is low, and the current production cost of briquette is relatively high.

[0003] There are some briquettes that include additives in the prior art, and the Chinese invention patent application publication specification CN1051582A discloses a new process for making combustible briquettes as the publication number, which consists of raw coal, carbonized sawdust, lime, red (yellow) mud, Composition of mixed base material such as charcoal powde...
