Abstract

The invention provides a coal additive which comprises 15-25 wt% of combustion adjuvant composing the mixture of nantokite, sodium chlorate and manganese sand, 50-70% of scale remover composing the mixture of borax, sodium chloride and magnesium carbonate, 4-6% of sodium carbonate desulfurizer, and 10-20% of lightweight calcium puffing agent. The invention can improve coal combustion efficiency, save energy and lower air pollution by the fire coal.

Description

Coal combustion improver
(1), affiliated field
What the present invention relates to is a kind of auxiliary agent of fuel.Specifically a kind of additive for fire coal with combustion-supporting, scale removal, reduction pollutant emission.
(2), background technology
Coal is a kind of important fuel, widespread use in many heating boilers and station boiler.Scatter fire of raw coal, not only thermo-efficiency is low, energy consumption is big, production cost is high, and owing to contain a large amount of objectionable impuritiess such as sulphur in the raw coal, can produce a large amount of noxious gas emissions.Because the obnoxious flavour that coal burning discharged has become atmospheric primary pollution source.In order to reduce coal burning to atmospheric pollution, improve the efficiency of combustion of coal, save energy reduces production costs, and some additive for fire coal also occurred seeing year.For example coal-saving agent, coal-fired promotor, ignition dope etc.They mainly are to be ignition dope with permanganate, carbonate, calcium oxide, are dedusting agent with SODIUMNITRATE, mantoquita, magnesiumcarbonate, are sweetening agent with soda ash, calcium oxide.Not only it is combustion-supporting for these additives, dust removing effects has much room for improvement, and does not have descaling function.
(3), summary of the invention
The object of the present invention is to provide a kind of combustion-supporting, good dedusting effect, have the coal combustion improver of good descaling function.
The object of the present invention is achieved like this: its weight consists of the ignition dope that the mixture by mantoquita, sodium chlorate, manganese sand of 15-25% is formed, the scale remover that the mixture by borax, sodium-chlor, magnesiumcarbonate of 50-70% is formed, the yellow soda ash sweetening agent of 4-6%, the light weight calcium swelling agent of 10-20%.
The present invention can also comprise like this some features: 1, mantoquita accounts for that 2-4%, sodium chlorate account for 8-12%, manganese sand accounts for 5-9% in the ignition dope that accounts for gross weight 15-25%.2, borax accounts for that 7-13%, sodium-chlor account for 40-50%, magnesiumcarbonate accounts for 3-7% in the scale remover that accounts for gross weight 50-70%.3, described mantoquita is a ventilation breather, and described light weight calcium is a lime carbonate.
The present invention is the mixture of multiple material, and each material cooperatively interacts, coordinates, and its major advantage is embodied in: 1, combustion-supporting effect obviously is better than other ignition dope, and can produce combustion-supporting effect rapidly.Mantoquita can resolve into cupric oxide after being heated, heavy metal has the effect of catalyzer, can play anticorrosion heat transfer effect at boiler tube surface attachment layer protecting film simultaneously.Sodium chlorate in the ignition dope is a strong oxidizer, and decomposes can produce active oxygen, can be rapidly and the coal reactive combustion.The Manganse Dioxide that contains in the manganese sand can play the effect that promotes that sodium chlorate is decomposed.2, features high scale-removing effect.General like product only lays particular emphasis on combustion-supporting, and has ignored the function of scale removal.Scale removal can effectively increase heat exchange area, improves heat-transfer effect, and the burnt dirt that facts have proved 1mm thickness may cause the waste of fuel more than 10%.Borax among the present invention can with the reactive metal oxide in the burnt dirt, dirt is come off, simultaneously can play preservative activity again.Be product monitoring result of the present invention below:

(4) specific embodiments
For example the present invention is done in more detail below and describes:
1, consists of the ignition dope that the mixture by mantoquita, sodium chlorate, manganese sand of 15-25% is formed by weight, the scale remover that the mixture by borax, sodium-chlor, magnesiumcarbonate of 50-70% is formed, the yellow soda ash sweetening agent of 4-6%, the ratio of the light weight calcium swelling agent of 10-20% is got raw material ready.With each raw material pulverizing, mix and make product.
2, get raw material ready in the ratio of mantoquita 2-4%, sodium chlorate 8-12%, manganese sand 5-9%, borax 7-13%, sodium-chlor 40-50%, magnesiumcarbonate 3-7%, yellow soda ash 4-6%, light weight calcium 10-20%.With each raw material pulverizing, mix and make product.
3, get raw material ready in the ratio of ventilation breather 2-4%, sodium chlorate 8-12%, manganese sand 5-9%, borax 7-13%, sodium-chlor 40-50%, magnesiumcarbonate 3-7%, yellow soda ash 4-6%, lime carbonate 10-20%.With each raw material pulverizing, mix and make product.
4, get raw material ready in the ratio of cupric oxide 2-4%, sodium chlorate 8-12%, manganese sand 5-9%, borax 7-13%, sodium-chlor 40-50%, magnesiumcarbonate 3-7%, yellow soda ash 4-6%, lime carbonate 10-20%.With each raw material pulverizing, mix and make product.
5, get raw material ready in the ratio of ventilation breather 3%, sodium chlorate 10%, manganese sand 7%, borax 10%, sodium-chlor 45%, magnesiumcarbonate 5%, yellow soda ash 5%, lime carbonate 15%.With each raw material pulverizing, mix and make product.
