Description
Technical field
The invention belongs to fire coal energy-saving emission-reducing Synergistic technique field, particularly a kind of fire coal energy-saving emission-reducing synergistic agent.
Background technology
Along with rapid economic development, energy-output ratio also increases sharply thereupon.The current Energy Mix of China remains based on coal.For reducing coal-fired pollution to environment, the human physical environment of depending on for existence of protection must reduce coal-fired consumption as far as possible, reduces discharge of harmful gases amount in the coal burning process, increases the efficient of coal burning, and this is human corporation responsibility.
Summary of the invention
The purpose of this invention is to provide a kind of energy that can make full use of coal burning, reduce quantity discharged in the coal burning process, increase the fire coal energy-saving emission-reducing synergistic agent of the efficient of coal burning.
Another object of the present invention provides a kind of using method of described fire coal energy-saving emission-reducing synergistic agent.
The objective of the invention is to realize by following technical proposals:
According to fire coal energy-saving emission-reducing synergistic agent of the present invention, it is characterized in that being formed by the component of following weight per-cent:
1) potassium permanganate or sodium permanganate 1～8%
2) nitrate of baryta 5～15%
3) SODIUMNITRATE 20～40%
4) Repone K 20～40%
5) Manganse Dioxide 15～30%
6) manganous sulfate 10～15%.
Potassium permanganate in the batching or sodium permanganate, nitrate of baryta, SODIUMNITRATE, Repone K all are used as oxygenant, and metal salt compound all has solid sulphur effect; Manganse Dioxide is coal-fired catalyzer, also is sulphur-fixing agent simultaneously; Manganous sulfate is coal-fired catalyzer.
The seepage force of fire coal energy-saving emission-reducing synergistic agent of the present invention is extremely strong, enters coal inside with regard to porous in several minutes, changes original charcoal chain of coal, thereby improves the burning of coal condition.
The coal that has added fire coal energy-saving emission-reducing synergistic agent of the present invention is packed into and is produced microexplosion behind the coal bunker of coal firing boiler under the effect of temperature and fire coal energy-saving emission-reducing synergistic agent, make coal bulk, volume increases, though in the boiler advance coal speed and thickness of coal seam does not become, but actual coal input quantity has reduced, and combustion efficacy improves.
The burning of coal process be successively through super-dry, preheating, four-stage burns, burnouts.Added the drying of the coal of fire coal energy-saving emission-reducing synergistic agent of the present invention; pre-heating stage obviously shortens; also can utilize the coal supply heating in coal bunker of stack gases waste heat; to shorten the drying of coal; warm; coal enters combustion phases after advancing people's burner hearth soon; and under the effect of fire coal energy-saving emission-reducing synergistic agent of the present invention; each temperature stage at coal combustion all gives competent oxygen; make the further explosion of coal; while fire coal energy-saving emission-reducing synergistic agent of the present invention constantly discharges very, and labile atom oxygen can enter in the hole of volatilization wound very soon; excite the microexplosion burning of coal again; furnace temperature is constantly raise; to originally can not participate in all combustiblematerials (non-oxidized substances of incendiary in the coal; metal and nonmetal etc.) all participates in burning; CO that produces in coal combustion process and water vapour and the catalyzer formed mixed gas that gasifies all can be fully burned, thereby reaches the purpose that improves boiler thermal output and economize on coal.
Oxygenant in the batching, sulphur-fixing agent, catalyzer can both make sulfurous gas be fixed in the slag with the form of vitriol under any temperature, reduce the discharging of sulfur dioxide in flue gas.And oxygenant, sulphur-fixing agent, catalyzer in the batching in burner hearth with sulphur, all produce microexplosion when carbon meets and form the microexplosion shockwave, the hard deposit that is attached on the boiler tube wall is come off separates with oxidation, boiler surface is often maintained a good state.
