Description

A distinctive feature of the proposed method of burning briquettes from chalk OTKH-DOG5 soda plants (leaving small items in the dump) in shaft furnaces consists in adding to the charge of briquettes koits} 1constock of sulfite bards in quantities up to C / o.

Briquettes are MANUFACTURED from the charge of the following composition: M. y. And trifle 87-95Vo; ant) acite 5-10% and sulphite sulfate concentrate bards 3-5%.

Making briquettes is made from chalk naturally | in ../ bones of irri ration; maximum pressure of briquetting presses.

Anthracite is introduced into the mixture for uniform decomposition of the fuel into the burning gas;

Adding to the briquette mass concentrates su; 1f1gg; 0 1 bard. has with.:; eduyuschis preprepitsystva.

Concentrates of organic bards, organic youth ;. H5Yajunimi. Netva:, 1I, contain derivatives of lignin 70-80. H corner. 10-15, “and mineral waters, in small calcium 10-15. According to the 3 rd, mentally: mu composition, the concentrate is characterized by a dry c-content gsm corner: Gguedo and oxygen-30%.

In dry distillation, the sulphite bards concentrate is coked. (, leaving u) of the products formed during the impact on bard v; juice :: temperatures without air access, characterized by m-1z npnxiepno yellow;: 1mk data: char to 60%, primary tar to, water to 15-) and others

By virtue of the composition indicated, the burning of the sulphite concentrate: the batch is accompanied by heat generation. On the top of the dry KOHLUH waste, this forms up to 5000 kcal. The organic part of the primate Gorenpie co-citrate is completely burned, and its mineral part, HiacT P1, is absorbed by calcium.

Thus, the introduction of up to 5% concentrate into the chalk mix results in savings in the range of 50-60% needed for roasting the fuel.

The coal and concentrate introduced into the Cretaceous blend are distributed but the entire mass of chalk thereby allows the firing process to run in the same manner and correctly; -with a large factor m. use and much faster.

Sulfite / bard concentrates dry quickly in air and in bales of heat gases. This promotes bonding (and increasing the strength of chalk briquettes.

By entering the high temperature zone, the briquette from such a mixture is additionally cemented and coked, thereby increasing its strength and crushing resistance.

The method of burning briquettes from carbonate lime in coal-fired furnaces with the introduction of fuel briquettes into the mixture, characterized in that the sulfite sludge concentrate concentrate is introduced into the mixture of briquettes in an amount up to 5%.
