Abstract
A sulfur-fixating briquette is made up of adhesive, coal powder, sulfur-fixating agent and combustion promoter and features ful combustion to increase thermal efficiency,decreasement in discharged harmful gas and dust and saving energy.
Description
The present invention relates to a kind of prescription of moulded coal.
In the prior art, the flue dust that the diffusing coal of burning in boiler produces is more, it is insufficient to burn, sulfur oxide produces more, not only thermal efficiency ratio is lower, and main be also relatively more serious to the pollution of environment, at present, also have both at home and abroad to bake sulphur formed coal, but to solid sulphur, smoke elimination, fully burn and can not reach perfect cooperation between the three.
The objective of the invention is: a kind of solid sulphur formed coal is provided, and it not only can fully burn with raising thermo-efficiency, but also can significantly reduce the discharging of obnoxious flavour and dust, therefore energy-conservation and environmental protection is all had extremely important meaning.
Technical scheme of the present invention is: a kind of solid sulphur formed coal, and it comprises following component:
(1). coal dust 90--98%;
(2). binding agent 1--3%;
(3) sulphur-fixing agent 1--7%.
The further technical scheme of the present invention is: a kind of solid sulphur formed coal, and it comprises following component:
(1). coal dust 90--98%:
(2). binding agent 1--3%;
(3). sulphur-fixing agent 1--7%;
(4). ignition dope 1--2%.
The more detailed technical scheme of the present invention is: a kind of solid sulphur formed coal, and it comprises following component:
(1). coal dust 90--98%;
(2). binding agent 1--3%;
Described binding agent is starch+caustic soda+water.
(3) sulphur-fixing agent 1--7%;
Described sulphur-fixing agent is a calcium oxide;
(4). ignition dope 1--2%;
Described ignition dope is a SODIUMNITRATE.
Advantage of the present invention is:
1. the present invention has added binding agent in coal dust, and coal dust is made moulded coal, and has added ignition dope, moulded coal is fully burnt,, reach purpose of energy saving to have improved the thermo-efficiency of moulded coal, but also significantly reduced the discharging of dust, reached the purpose of environmental protection.
2. the present invention has added sulphur-fixing agent in coal dust, can generate not volatile material with the reaction of Salmon-Saxl in the coal dust, thereby significantly reduce discharge of harmful gases.
The present invention not only sulfur-fixing rate can reach more than 80%, and dust concentration also reduces to Lin Geman below 0.5, moulded coal can orientation be bloomed when burning simultaneously, and the fixed carbon in the coal dust is fully burned.
Below in conjunction with embodiment the present invention is further described:
Embodiment: a kind of solid sulphur formed coal, it comprises following component:
(1). coal dust 90--98%;
(2). binding agent 1--3%;
Described binding agent is starch+caustic soda+water.
(3). sulphur-fixing agent 1--7%;
Described sulphur-fixing agent is a calcium oxide;
The present invention has added binding agent in coal dust, coal dust is made moulded coal, and has added ignition dope, moulded coal is fully burnt,, reach purpose of energy saving to have improved the thermo-efficiency of moulded coal, but also significantly reduced the discharging of dust, reached the purpose of environmental protection; The present invention has added sulphur-fixing agent in coal dust, can generate not volatile material with the reaction of Salmon-Saxl in the coal dust, thereby significantly reduce discharge of harmful gases; The present invention not only sulfur-fixing rate can reach more than 80%, and dust concentration also reduces to Lin Geman below 0.5, and moulded coal can orientation be bloomed when burning simultaneously, and the fixed carbon in the coal dust is fully burned.
The present invention transports and stacks conveniently, and simple to operate clean, combustion time is long, and heat conduction is fast, and the thermo-efficiency height is incandescent state during burning, and stovepipe with the naked eye almost can't see soot emissions outward.
Following table compares for the relevant data of the present invention and common lump coal: (50Kg)
Moulded coal lump coal relatively get angry time 0.73 degree/minute 0.70 degree/minute+4.28% 465 minutes 369 minutes+26% total burning time average intensity of fire 191.7 Grams Per Minutes 169.3 Grams Per Minutes+13.23%
Simultaneously, the sulfur-fixing rate of moulded coal is 99.25%, has improved 75.04% than the sulfur-fixing rate 24.2% of lump coal.
Claims (5)
1 one kinds of solid sulphur formed coals, it comprises following component:
