According to raw material mixing ratio, the briquettes fall into three classes: 1, long-flame coal (4,000 to 6,000 kilocalories) which is prepared from 80 to 90 percent of main material, 2 to 5 percent of clay, 3 to 5 percent of desulfurizer, 2 to 4 percent of waterproofing agent, 3 to 5 percent of auxiliary material and 1 to 3 percent of water; 2, medium-flame coal (3,000 to 4,000 kilocalories) which is prepared from 60 to 80 percent of main material, 5 to 10 percent of clay, 3 to 5 percent of desulfurizer, 3 to 5 percent of waterproofing agent, 10 to 25 percent of auxiliary material and 1 to 3 percent of water; and 3, thermal-insulation coal (2,000 to 3,000 kilocalories) which is prepared from 40 to 60 percent of main material, 5 to 13 percent of clay, 3 to 5 percent of desulfurizer, 3 to 5 percent of waterproofing agent, 20 to 45 percent of auxiliary material and 1 to 3 percent of water.
Description
Technical field
The present invention relates to a kind of solid fuel and working method thereof, belong to the fuel manufacture field, refer to that specifically a kind of discharge that reclaims with Industrial Boiler makes the Type Coal And Its Production Methods of main raw material production.
Background technology
At present, the technology of producing moulded coal is a lot, wherein mainly with hard coal, mixed coal, coke powder, flyash, biological raw material (straw, sawdust etc.), furfural, coal gangue, coal slime etc. as main raw material.Add subsidiary material such as sulphur-fixing agent, water-resisting agent, solidifying agent in addition again and produce, these methods, consumes energy are too high, but heat is not high, and are on fire too slow during burning; Also have present Mainstream Packs product of coal all to use coal slime, coal slime is settled out in the raw coal cleaning process, contains a large amount of impurity (being ash); The quality of raw coal is low more, and the heat of coal slime is low more, and the impurity that coal slime contains is bigger (ash is big more) just; The quality product of producing is just unstable; Heat is also unstable, and the pollution of discharging is just big, and the harm of environment is still existed.
Summary of the invention
The present invention is directed to above-mentioned having now all is the problem that technology exists, and has proposed a kind of discharge that reclaims with Industrial Boiler and has made the moulded coal of main raw material production, and proposed the working method of above-mentioned moulded coal.
A kind of discharge that reclaims with Industrial Boiler of the present invention is made the moulded coal of main raw material production, it is characterized in that through regulating the proportioning of main raw material, the moulded coal that can produce three kinds of labels promptly 1, go up kindling 4000-6000 kilocalorie; 2, middle kindling 3000-4000 kilocalorie; 3, insulation coal 2000-3000 kilocalorie.
A kind of discharge that reclaims with Industrial Boiler of the present invention is made the moulded coal of main raw material production, it is characterized in that mainly comprising the component of following three kinds of label moulded coals:

Described a kind of discharge that reclaims with Industrial Boiler is made the moulded coal of raw material production, it is characterized in that described sweetening agent is a lime powder, its content 1, last kindling 3-5%; 2, middle kindling 3-5%; 3, insulation coal 3-5%.Said water-resisting agent is a flyash, its content 1, last kindling 2-4%; 2, middle kindling 3-5%; 3, insulation coal 3-5%.The content of the discharge that described Industrial Boiler reclaims is 1, go up kindling 80-90%; Middle kindling 60-80%; Insulation coal 40-60%.Described clay is a soil property of firing clay brick, and its content is 1, goes up kindling 2-5%; 2, middle kindling 5-10%; 3, insulation coal 5-13%.Described subsidiary material coal slime, hard coal, coke powder, mixed coal, flyash, straw, furfural, boiler ash sediment equal size are 1, go up kindling 3-5%; 2, middle kindling 10-25%; 3, insulation coal 20-45%.Described water is 1-3%.
Realize that the above-mentioned discharge that reclaims with Industrial Boiler makes the method for the moulded coal of raw material production, it is characterized in that:
1, the discharge dry (methods such as Exposure to Sunlight, natural ventilation, oven dry) that Industrial Boiler is reclaimed, water ratio about 16%;
2, with clay somely be crushed to below 50 orders, sweetening agent (lime powder) is crushed to below 50 orders, subsidiary material coal slime, hard coal, coke powder, mixed coal, flyash, straw, furfural, boiler ash sediment etc. are crushed to below 50; The discharge of getting the Industrial Boiler recovery is some, carries out the moulded coal preparation of following three kinds of labels.
A, last kindling: (4000-6000 kilocalorie)
A, get the discharge that the Industrial Boiler of 80-90% weight part reclaims;
