Abstract
The invention discloses a high heat pellet fuel, and relates to the technical field of a solid fuel, the high heat pellet fuel is made from the following raw materials by weight: 20-30 parts of crop straw, 30-40 parts of other wood chip, 10-15 parts of pine sawdust, 5-10 parts of bagasse and 1-2 parts of calcium oxide; the preparation method is as follows: crushing the above materials to obtain grains, taking the material components according to the weight proportion, fully mixing, drying the moisture of the mixed crushed grains to 6-13%, extruding and granulating the dry grains to obtain the raw pellet fuel. The high heat pellet fuel makes full use of a variety of waste fuels, does not use chemical additives, has reasonable fuel raw material ratio, can fully release the fuel heat, by the calcium oxide, slagging during combustion can be effectively prevented, and by the pine, fuel bonding and combustion supporting can be realized.
Description
Technical field
The present invention relates to solid-fuel technology field, be specifically related to a kind of high calorie granular fuel.
Background technology
Granular fuel, domestic mainly with the alternative bioenergy that the stalk such as sweet sorghum stalk, maize straw, cotton stalk, wheat or rice straw, branch, reed is Raw material processing.Be mainly used in the boiler of Substitute coal; Family warms oneself, the fireplace etc. in European winter.Granular fuel now main in the Inner Mongol, Heilungkiang, Jilin, Anhui, Sichuan, Shanxi, the development of the provinces and cities such as Shandong be very fast, main concentrating is following a few class at present: refined Tianjin sweet sorghum stalk: utilize refined Tianjin sweet sorghum stalk processing ethanol or former slag after drinking, by high temperature extruding forming, become granular fuel; Cotton stalk: the province cotton production areas such as Xinjiang, Shandong, mainly utilizes cotton stalk processing granular fuel; The granular fuel of wheat stalk, rice straw and assorted branch co-grinding post-treatment.
Granular fuel is the recyclable fuel that a kind of pole has market to advance, but the limited material that current granular fuel utilizes, can not well some discarded materials be made full use of, and current granular fuel structural instability, and easy slagging scorification during burning.
Summary of the invention
The object of the invention is the defect for above-mentioned prior art, provide a kind of high calorie granular fuel, there is the advantage of sufficient combustion.
Object of the present invention can be achieved through the following technical solutions:
A kind of high calorie granular fuel, is made up of the raw material of following weight part: 20 ~ 30 parts of agricultural crop straws, 30 ~ 40 parts of other wood chips, pine sawdust 10 ~ 15 parts, 5 ~ 10 parts of bagasse, 1 ~ 2 part, calcium oxide; Preparation method is: above all material is carried out pulverizing and obtains particle, get each described feed composition by above weight fully to mix, then the pellet moisture of gained after co-grinding is dried to 6 ~ 13%, finally dry granules is carried out extruder grain, obtain raw granular fuel.
Preferably, described agricultural crop straw is one or more in maize straw, rice straw, wheat stalk.
Preferably, other wood chip described be bamboo wood, Chinese chestnut wooden, elm, willow, jujube wood, oak one or more.
Preferably, described pine sawdust and other wood chip pulverize rear granularity is 0.5 ~ 2mm.
Preferably, rear granularity pulverized by described agricultural crop straw and bagasse is 3 ~ 5mm.
Preferably, described calcium oxide powder is broken to 0.2 ~ 0.5mm.
Beneficial effect of the present invention: the present invention takes full advantage of multiple discarded fuel, and do not adopt chemical additive, and reasonable ratio between fuel feedstocks, can fully discharge fuel heat, slagging scorification when effectively preventing burning by calcium oxide, realizes the bonding of fuel and combustion-supporting by pine.
