Method of producing new fuel

FIELD: process engineering.

SUBSTANCE: invention relates to method of fuel production. Fuel is produced in mixing lignin with metallurgy wastes. Note here that lignin moisture content may vary. Chips of steel and foundry iron parts and scale are used as metallurgy wastes. Said mix comprises lignin in amount of 70-90 wt % and scale in amount of 10-30 wt %.

EFFECT: universal high-energy fuel.

 

The invention relates to a fuel, and more particularly to a waste hydrolytic production from waste and mechanical production.

There are many copyright certificates and patents for briquetting and use of lignin as fuel. A.S.№229450, №958467, №1544789, №1286613.

The closest to the technical nature of the claimed method is a method of producing fuel briquettes from peat, coal, lignin. A.S. No. 1286613.

The known method has several disadvantages: it briquetting, drying, grinding, mixing.

Peat - 45-55; coal - 20-30; lignin 20-30. As the USSR №1286613, MKI C10F 7/06 - 1987

Waste mechanical production include: chips from steel, cast iron parts, as well as scale. Try to compress and re-melted, but the cost of pressing very significant, and when remelting lost up to half of the weight as if the wastes are not extruded.

The problem underlying the claimed process is the establishment of a simple and economical way by avoiding operations briquetting, drying, grinding. There is only one operation - mixing.

The purpose of the invention is to create a universal energy-dense fuel, as the shaving waste metalloproizvoditeli plays a role in the combustion of thermite mixture. Thermite mixture consists of 70-85% scale and allia is newago powder almost 15-30% and is caused by burning thermomete at a temperature of 2300-2700°C.

The problem is solved in the following way: lignin any moisture is mixed with the waste mechanical production, while the mechanical part of the waste production to be crushed, and this mixture is fed into the furnace of any fired boiler, the combustion temperature increases on average by 200°C testing laboratory analysis.

Lignin - 70-90%; chips and scale of 10-30% by weight.

The calorific value of the dry lignin 5500-6500 cal/kg, wet - 65%, from 1500 to 1650 calories/kg Specific gravity of 1.15.

Humidity from lignin passes for metal shavings in the form of rust (scale), thereby increasing the temperature of combustion, as formed by thermite mixture, the more rust (scale), the higher the combustion temperature.

Listed a set of features allows comparison with the prototype to make the claimed method is easier to implement with reduction operations such as drying, grinding, and with the exception of such costly derivatives, as peat and coal.

The presence of the distinctive features of the prototype of the existing features allows you to admit the new method.

The prior art has identified solutions that would have the signs consistent with the distinctive features of the claimed method, so the latter meets the condition of "inventive step".

Forex is the efficiency of the use of the proposed method in the industry allows us to conclude that it conforms to the criterion "industrial applicability".

The method of obtaining fuel, comprising mixing lignin any moisture from waste mechanical production, representing scraps of steel and iron parts and scale, with a corresponding ratio of mixture components: lignin 70-90%, chips and scale of 10-30%.
