Description
Technical field
The present invention relates to Coal Energy Source more particularly to additive for fire coal, specifically a kind of coal-saving agent.
Background technology
Coal is one of the main energy in one, China and industrial chemicals, especially as the energy, is answered in modern industry
With most common energy source raw material.However, as the deposit of coal resources on the earth is fewer and fewer, the price of coal is higher and higher,
The requirement that country and relevant departments discharge fume to coal burning is increasingly stringenter, and how to be improved the utilization rate of coal, is reduced it and bring
Pollution just at important world's project.According to present research direction, coal-saving agent can effectively solve the problem that these problems,
However existing coal-saving agent only has begun to take shape, effect unobvious, and there is additive amounts big, pollution environment, Green's blackness
Disadvantage not up to standard is far from reaching desired effect.
Invention content
Technical problem solved by the invention is to provide a kind of coal-saving agent, to solve the disadvantage in above-mentioned background technology.
Technical problem solved by the invention is realized using following technical scheme：
Coal-saving agent is made of catalyst, combustion adjuvant, bleeding agent, leavening agent, purificant, dispersant and sulphur-fixing agent, these components
It is respectively catalyst 6~12%, combustion adjuvant 1~7%, bleeding agent 25~35%, leavening agent 25~35%, cleaning by weight percentage
Agent 7~15%, dispersant 10~20% and sulphur-fixing agent 7~12%.
In the present invention, the catalyst is one or more of titanium trichloride, nickel sulfate, cerous nitrate and chromium trioxide
Mixture, the combustion adjuvant be ammonium persulfate, the bleeding agent be water, the leavening agent be sodium chloride and potassium chloride one kind
Or two kinds of mixture, the purificant are cyclopentadiene, the dispersant is polyoxyethylene ether, and the sulphur-fixing agent is calcium oxide
With the mixture of sodium carbonate.
Coal-saving agent is matched based on said components, is orange-yellow liquid, density 1-1.1g/cm3 is dissolved in water entirely, and pH is in neutrality,
Coal additive amount 0.05%, i.e., coal per ton add 0.5kg coal-saving agents.
Advantageous effect：
The present invention can improve furnace body burning condition, enhance gas permeability of coal seam, coal is made fully to burn, and improve the coal-fired thermal efficiency, drop
Low smoke discharge amount improves heat conduction efficiency, Gu cigarette drops in sulphur, reduces the discharge of CO, SO2, reduces environmental pollution, to reach
Combustion-supporting, solid sulphur, energy saving, desulfurization purpose, can economize on coal 5%-10%, improve 10% or more firepower, removing carbon 50-90%, drop
Sulphur 20-50%.
With reference to embodiment, the invention will be further described.
Specific implementation mode
In order to make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, tie below
Closing example, the present invention will be described in detail.
The group of coal-saving agent is divided into 6~12%, combustion adjuvant 1~7%, bleeding agent 25~35%, leavening agent 25~35%, purificant 7
~15%, dispersant 10~20% and sulphur-fixing agent 7~12%, the catalyst are titanium trichloride, nickel sulfate, cerous nitrate and three oxidations
The mixture of one or more of chromium, the combustion adjuvant are ammonium persulfate, and the bleeding agent is water, and the leavening agent is chlorination
One or two kinds of mixtures of sodium and potassium chloride, the purificant are cyclopentadiene, and the dispersant is polyoxyethylene ether, institute
State the mixture that sulphur-fixing agent is calcium oxide and sodium carbonate.
Embodiment one：Coal-saving agent component is catalyst chromium trioxide 10%, combustion adjuvant ammonium persulfate according to weight percent
7%, bleeding agent water 40%, leavening agent sodium chloride 20%, purificant cyclopentadiene 6%, dispersant polyoxyethylene ether 7%, sulphur-fixing agent oxidation
The mixture 10% of calcium and sodium carbonate, is diluted with water, is mixed into coal, compared with the coal for being not added with coal-saving agent, ash content carbon
It is down to 12.98% by 17.45%, pernicious gas reduces 60% or more, and lingemann blackness is less than 1 grade, coal saving rate 11.2%.
Embodiment two：Coal-saving agent component according to weight percent be catalyst titanium trichloride, nickel sulfate, cerous nitrate it is mixed
Close mixture 22%, the purificant ring of object 7%, combustion adjuvant ammonium persulfate 3%, bleeding agent water 40%, leavening agent sodium chloride and potassium chloride
The mixture 6% of pentadiene 10%, dispersant polyoxyethylene ether 12%, sulphur-fixing agent calcium oxide and sodium carbonate, is diluted with water, is mixed into coal
In charcoal, compared with the coal for being not added with coal-saving agent, ash content carbon is down to 9.35% by 12.65%, pernicious gas reduce 60% with
On, lingemann blackness is less than 1 grade, coal saving rate 11.9%.
Meanwhile after adding coal-saving agent, removing ash of boiler slag number is greatly reduced, and does not occur lime-ash close-burning phenomenon.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
