Abstract

The invention relates to an energy-saving and pollution-relieving liquid coal nano combustion improver and a preparation method and a preparation device thereof, and belongs to the field of combusting coal combustion improving additives. The energy-saving and pollution-relieving liquid coal nano combustion improver comprises the following components in percentage by mass: 15 to 23 percent of emulsifier which consists of polyoxyethylenated castor oil and sorbitan tristearate, 18 to 27 percent of penetrating agent which consists of sodium butylnaphthalene sulfonate and sodium diethylhexyl sulfosuccinate, 12 to 20 percent of castor oil serving as an oxidant, 20 to 47 percent of activator which consists of polyvinyl alcohol and beta-methyl acrylic acid and 8 to 10 percent of nano material which consists of TiO2, ZnO, MgO and Fe2O3. When the energy-saving and pollution-relieving liquid coal nano combustion improver is used, a special coal combustion improver spray atomizing system is used to uniformly spray the improver onto coal according to a ratio of 0.04 to 0.06 percent. The coal nano combustion improver prepared by the invention has the advantages of stable performance, convenience for use, as well as capability of improving the combustion efficiency of coal, reasonably improving combustion environment, capturing sulfur, removing nitrates, saving energy and reducing emission.

Description

technical field [0001] The invention relates to an energy-saving and pollution-reducing liquid coal nano-combustion aid, a preparation method and a device, and belongs to the field of coal-burning combustion-supporting additives. Background technique [0002] Coal is one of the main energy sources in the world. Therefore, rational use of coal resources and improvement of coal combustion efficiency not only have high economic benefits, but also have great social significance. It is of great significance to study the combustion methods that are beneficial to the five aspects of high-efficiency combustion, low-load stable combustion, low pollution, prevention of slagging and high-temperature corrosion. [0003] Many researches have been carried out around the above-mentioned problems at home and abroad, and a series of combustion accelerants for coal have been developed and roughly divided into four categories: the first category uses strong oxidants (such as nitrates, chlorate...
