Abstract

The invention discloses a composite type coal-saving and catalyzing combustion improver, comprising the following components in weight by percentage: 40-60 parts of accelerating agent, 0.5-1% of inducing agent, 10-20% of catalyst, 8-15% of dispersant and 20-40% of stable sulfur fixing agent, wherein an alcohol-based fuel is used as the accelerating agent and calcium peroxide is used as the inducing agent; the catalyst is formed by 20-30% of nano iron sesquioxide, 20-30% of nano ferrous oxide, 20-30% of nano ferroferric oxide, 5-10% of nano manganese dioxide, 10-15% of sodium carbonate and 10-15% of potassium carbonate; a polyoxyethylene based ether surfactant is used as the dispersant; and the stable sulfur fixing agent is formed by 20-30% of calcium carbonate, 20-30% of calcium silicate and 50-60% of calcium oxide. The combustion improver is added into fire coal and then the fire coal is combusted, so that the coal saving rate can be more than 30% and the SO2 discharging amount can be effectively reduced after the fire coal is combusted.

Description

technical field [0001] The invention relates to the technical field of combustion additives, in particular to a composite coal-saving catalytic combustion aid. Background technique [0002] At present, my country's power plants, industrial boilers and other industries mainly use non-renewable energy such as coal as fuel. However, the incomplete combustion of coal and the incomplete combustion part enter the atmosphere and waste residue, causing pollution and waste of energy. With the continuous development of social industrialization, energy problems have become increasingly prominent. How to save limited coal resources, improve coal combustion efficiency, and reduce environmental pollution caused by coal combustion has become a research topic for scientific researchers. At present, coal-burning additives are mostly used to achieve coal-saving purposes. Among the existing coal-saving additives, the mechanism is mainly to use accelerators, catalysts, etc. to fully contact the...
