Description
Technical Field
The invention belongs to the technical field of flame retardants, and particularly relates to a semi-coke combustion improver.
Background
The basic characteristics of natural resources in China are rich coal, poor oil and little gas, which determines the important position of coal in primary energy. Coal is relatively abundant in storage compared to oil and natural gas, and accounts for 11.60% of world reserves. The total amount of coal resources in China is 5.6 trillion tons, wherein the proven reserves are 1 trillion tons, which account for 11 percent of the total reserves in the world, and the coal-producing large country in the world is the first coal-producing large country. However, as people continuously mine, the storage capacity of coal is less and less, and coal is a non-renewable resource, so that how to improve the combustion rate and the utilization rate of coal becomes a research focus.
Semi coke is a solid product of low-temperature destructive distillation step conversion in low-metamorphic coal, is determined to be a cleaner energy source, and has the characteristics of high fixed carbon, high chemical activity, low ash content, low aluminum, low sulfur, low phosphorus and the like. The semi-coke has better quality and combustion performance than anthracite, and has lower price than anthracite. The low-rank coal reserves in China are rich, the development of the semi-coke industry is the requirement of the national energy optimization strategy, the semi-coke has wide prospect and sufficient market. Based on the above excellent characteristics, the semi-coke has attracted high attention as an alternative fuel for domestic and foreign enterprises, and the semi-coke with low price is always explored as an alternative fuel. Although various coal additives and combustion improvers are available on the market, combustion improvers capable of really solving the problem of burning of semi-coke are not available, the semi-coke has a high burning ignition point, is extremely easy to burn incompletely and insufficiently in the burning process, and has high content of nitrogen oxides and sulfides generated by burning, so that environmental pollution is extremely easy to cause.
The invention patent with publication number CN102229835A provides an environment-friendly energy-saving combustion improver for coal, which can prolong the combustion time by adding various high-hardness solid metal oxides to ensure more complete combustion(ii) a The invention patents with publication numbers of CN106336929A, CN105132076A and CN111534356A use nano materials for combustion supporting, but the formulation components of the three patents are relatively complex, part of the substances are easy to generate toxic substances, the substances are easy to explode in the combustion process, and the industrial application effect is very limited; the invention patents with publication numbers of CN102453583A, CN102888260A and CN103146456A simplify the combustion improver of the industrial formula into four components, and although the invention patents have the characteristics of simple and convenient process, low cost and the like, the combustion improver has very limited combustion-supporting effect on the semi coke; the invention patent with publication number CN104987913A discloses a combustion improver added with activated carbon as a leavening agent and an adsorbent, wherein CaCl is added2Can improve the calcium-sulfur ratio and effectively reduce SO2The emission amount is reduced, but the formula cannot reduce the burning ignition point of the semi-coke; the invention patents with publication numbers CN104774671A, CN106753683A and CN108611155A add more than one oxidant in the combustion improver formula, but economically limit the application of the combustion improver in industry; in the invention patent with publication number CN 102517119A, sodium dodecyl benzene sulfonate with emulsification is added in the formula of combustion improver, but the industrial applicability of diesel oil and cyclopentadienylferrocene is not great in the formula.
Disclosure of Invention

When the semi-coke combustion improver is used, the semi-coke combustion improver and the semi-coke are mixed according to the weight ratio of 3: 100.
Compared with the prior art, the semi-coke combustion improver has the advantages that the types of the formula components are less, the formula component products are easy to obtain, and the cost is low; potassium permanganate added into the combustion improver has the characteristic of generating oxygen by decomposition, so that the peroxy combustion is realized during the burning of the semi coke, the proportion of incomplete burning of the semi coke is reduced, and the burnout rate is improved; calcium chloride and ammonium nitrate are added into the combustion improver, so that the ignition point of the semi-coke can be reduced, the ignition time can be shortened, and the calcium chloride can also combine with sulfur dioxide to play a role in reducing the emission of sulfides; basic copper carbonate is added into the combustion improver, and the basic copper carbonate is decomposed at high temperature to generate copper oxide, so that the reduction of nitric oxide into nitrogen and oxygen can be promoted, and the emission of nitrogen oxides is reduced; the combustion improver is added with sodium dodecyl benzene sulfonate and active carbon, and the sodium dodecyl benzene sulfonate is used as a surfactant to provide more adsorption sites for the active carbon to adsorb redundant nitric oxides and sulfides. Experiments prove that the semi-coke combustion improver can greatly reduce the ignition point of the semi-coke, reduce the burnout time of the semi-coke, ensure the complete and sufficient combustion of the semi-coke, and reduce the discharge amount of nitrogen oxide and sulfide gas generated by the combustion of the semi-coke.
