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, referring in particular to kaolin is anti-scorch, the decoking agent of boiler of main raw material.
Technical background
During the coal-fired power station boiler burning, the mineral substance in the coal has formed coal ash.Coal firing boiler is because hot strength is big, temperature of combustion is high, ash fusion point is low, and the coal ash of fusion and semi-melting state can deposit, be bonded on the boiler surface with the form of coking, contamination usually.And slagging scorification, contamination are in case form; Because the lime-ash thermal conductivity is low, can reduce caloric receptivity in the boiler stove, not only can reduce boiler thermal output; Also can limit boiler load; Thereby overall thermal equilibrium process in the destruction stove, even can cause the accident of compelled blowing out, directly influence security, economy and the safety of boiler operatiopn.The formation of components of coal ash is to influence the coal ash melting characteristic, causes the basic factor of the serious slagging scorification of boiler, contamination.Developing a kind ofly can directly increase the ratio that contains the high ash melting point compound in the ash, improves the fusing point of coal ash, slag, improves its crystallization property, and the boiler that fundamentally change the coal ash slagging scorification, stains characteristic is anti-scorch, decoking agent is that the coal firing boiler industry is badly in need of.
Summary of the invention
The technical problem that the present invention will solve provides anti-scorch, the decoking agent of a kind of boiler; This boiler is anti-scorch, decoking agent with kaolin is main raw material; It is added in coal or other solid fuel can changes high ash melting point components in proportions in the ash, directly improve fusion point of ash, change cindery crystallization and form structure; Eliminate or alleviate the slagging scorification and the contamination problem of boiler, play anti-scorch, decoking effect boiler.
The technical problem that the present invention will solve is realized by following scheme: a kind of anti-scorch, decoking agent; With kaolin is main raw material, it is characterized in that: each component and shared mass percent are: the compound 0.01～50% of the compound 0.05～98% of kaolin 1～99.9%, aluminium, the compound 0.01～20% of titanium, magnesium, the compound 0.01～30% of calcium, the compound 0.001～5% of 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 during use and participate in the fuel combustion reaction.Investing method is participated in combustion reactions for sending into separately in the boiler furnace, the mode that also can sneak in the coal is carried out.Composition according to the solid fuel ignition product constitutes; Anti-scorch, the decoking agent of corresponding this boiler of interpolation in fuel; Can directly improve the products of combustion fusing point; Improve the crystallisation process of solid particulate, effectively alleviate in the fuel high-temp combustion process, the fused products of combustion is in coking, the contamination of burner hearth, heating surface.
Embodiment
Embodiment: make anti-scorch, the decoking agent of 1000kg, wherein kaolin 900kg, aluminum oxide 80kg, titanium oxide 8kg, Natural manganese dioxide 5kg, lime carbonate 5kg, copper sulfate 2kg.
