Description

A kind of combustion-supporting agent for fuel coal with high stability
Technical field
The present invention relates to combustion adjuvant technical field, more particularly to a kind of combustion-supporting agent for fuel coal with high stability.
Background technology
Catalytic combustion adjuvant for coal is roughly divided into four major classes：The first kind is with strong oxidizer (such as nitrate, chlorate, high chlorine Hydrochlorate, permanganate, bichromate) based on, or it is aided with Nacl, MnO2、Fe2O3, sugar, urea, phosphorus and antimony trisulfide etc., it is or auxiliary With CaO, MgO, Na2O sulphur-fixing agent；Second class is based on various metal oxides and mine tailing；3rd class using low molecule alcohol as It is main；4th class is based on carboxylate metal salt, including the acylate such as acetate, oxalates, succinate, soap.The A kind of combustion adjuvant using strong oxidizer as main material, though the burning-point to reducing material, to promoting burning to have certain effect, It is that the quick burning strong oxidizer stability is poor, rapid after being heated to decompose, short combustion system effect, actual efficacy is limited. Meanwhile so property strong oxidizer belongs to equipment of Flammable and Explosive Materials to above-mentioned speed, easily occurs during processing, transport, storage and use Safety problem.
Such as Chinese patent CN105802694A discloses a kind of combustion-supporting agent for fuel coal for being used to promote coal-fired completely burned, It is characterized in that its composition of raw materials is：Magnesium chloride 20-25 parts weight；Nitric acid 25-35 parts weight, sodium nitrate 25-35 parts weight, potassium chlorate 8- 12 parts of weights, sodium chlorate 10-15 parts weight.When the fire coal of the combustion adjuvant of the technical scheme burns in stove, sodium chlorate, potassium chlorate, nitre Sour sodium and potassium nitrate can be at different temperature（200-600℃）It is decomposed successively and releases oxygen, so that fire coal is whole Oxygen replenishment is constantly obtained in combustion process, effectively improves the situation of coal-fired ischaemia, enables fire coal completely burned.Reason By the possibility for above having implementation, but sodium chlorate, potassium chlorate, sodium nitrate and the potassium nitrate in being formulated can decomposite the same of oxygen When, pernicious gas releasing is also had, is unfavorable for the protection of environment, belongs to the typical case to attend trifles and neglect essentials.
Such as Chinese patent CN103965986A discloses a kind of novel water-based combustion-supporting agent for fuel coal again, it is characterised in that presses Calculated according to parts by weight, the novel water-based combustion-supporting agent for fuel coal by 5~10 parts of potassium permanganate, 3~8 parts of potassium chlorate, 8~12 parts Borax, 5~10 parts of manganese dioxide, 5~10 parts of di-iron trioxides, 45~55 parts of suspending agents and 10~30 parts of water compositions；It is described outstanding Floating agent is reacted by water, soluble cellulose, sodium hydroxide solution and waterglass to be made.The technical scheme is mainly from reduction coal dust While setting about considering in terms of ignition point and raising efficiency of combustion two, but select potassium permanganate as preferable oxidant, its Also have that strong oxidizer stability is poor, it is rapid after being heated decompose, combustion system is acted on short, the shortcomings that actual efficacy is limited, Therefore need further desirable for improvement.
