Abstract
The invention discloses a boiler coke preventing and eliminating agent by taking kaolin as the main raw material. The boiler coke preventing and eliminating agent comprises the following compositions in mass percent: 1-99.9% of kaolin, 0.05-98% of alumina compound, 0.01-20% of titanium compound, 0.01-50% of magnesium compound, 0.01-30% of calcium compound and 0.001-5% of copper compound. The boiler coke preventing and eliminating agent is correspondingly added to fuel, the melting point of a combustion product is directly increased, and the coking and contamination of molten combustion product on a hearth and a heated surface are effectively relieved in the high-temperature combustion process of the fuel.
Description
Technical field
The present invention relates to a kind of anti-scorch, decoking agent, refer in particular to and take that the boiler that kaolin is main raw material is anti-scorch, decoking agent.
Technical background
During coal-fired power station boiler burning, the mineral substance in coal has formed coal ash.Coal firing boiler is because hot strength is large, temperature of combustion is high, ash fusion point is low, and the coal ash of melting and semi-melting state can deposit, be bonded on boiler surface with the form of coking, contamination conventionally.And once slagging scorification, contamination form, because lime-ash thermal conductivity is low, can reduce caloric receptivity in Boiler Furnace, not only can reduce boiler thermal output, also can limit boiler load, thereby overall thermal equilibrium process in destruction stove, even can cause the accident that is forced to blowing out, directly affects security, economy and the reliability of boiler operatiopn.The formation of components of coal ash is to affect coal ash, causes the basic factor of boiler Serious Slagging, contamination.Develop a kind of ratio that can directly increase in ash containing high ash melting point compound, improve the fusing point of coal ash, slag, improve its crystallization property, the boiler that fundamentally changes coal ash slagging scorification, fouling characteristics is anti-scorch, decoking agent is that coal firing boiler industry is badly in need of.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of boiler is anti-scorch, decoking agent, this boiler is anti-scorch, decoking agent be take kaolin as main raw material, be added on the ratio that can change high ash melting point composition in ash in coal or other solid fuel, directly improve fusion point of ash, the crystallization that changes lime-ash forms structure, slagging scorification and the contamination problem of eliminating or alleviate boiler, play anti-scorch, decoking effect to boiler.
The technical problem to be solved in the present invention is realized by following scheme: a kind of anti-scorch, decoking agent, take kaolin as main raw material, it is characterized in that: each component and shared mass percent are: the compound 0.05～98% of kaolin 1～99.9%, aluminium, the compound 0.01～20% of titanium, the compound 0.01～50% of magnesium, the compound 0.001～5% of the compound 0.01～30% of calcium, copper.The compound of aluminium, titanium, magnesium, calcium, copper can be oxide compound, oxyhydroxide, carbonate, vitriol etc.
This boiler is anti-scorch, decoking agent utilizes cheap kaolin to make main raw material, with Powdered solid granulates form even blend, sends into or sprays into boiler furnace and participate in fuel combustion reaction during use.Investing method is participated in combustion reactions for sending into separately in boiler furnace, and the mode that also can sneak in coal is carried out.According to the composition of solid fuel ignition product, form, anti-scorch, the decoking agent of corresponding this boiler of interpolation in fuel, can directly improve products of combustion fusing point, improve the crystallisation process of solid particulate, effectively alleviate in high temp. combustion of fuel process, the products of combustion of melting is in coking, the contamination of burner hearth, heating surface.
Embodiment
Embodiment: making 1000kg is anti-scorch, decoking agent, wherein kaolin 900kg, aluminum oxide 80kg, titanium dioxide 8kg, magnesium oxide 5kg, calcium carbonate 5kg, copper sulfate 2kg.
