Abstract

The invention relates to mixed coal water slurry fuel, in particular to coal tar and coal water slurry mixed fuel and a preparation method thereof. The coal tar and coal water slurry mixed fuel comprises the following raw materials in parts by weight: 55-65 parts of superfine pulverized coal, 10-25 parts of coal tar, 10-25 parts of water, 2-5 parts of flame accelerator, 2-5 parts of dispersing agent and 4-10 parts of emolsifier. The mixed fuel has the benefits that: (1) a finish product is low in viscosity, the combustion efficiency of coal water slurry is effectively improved, the combustion is more completely and sufficiently, (2) the stability of the coal water slurry is improved, the coal water slurry can be stored for a long term, (3) the mixed fuel is in a liquid slurry shape, can be pumped, atomized, stored and transported like oil and is convenient to transport, and (4) the combustion is sufficient, the carbon smoke pollution is greatly reduced, and the mixed fuel is environment-friendly and energy-saving.

Description

technical field [0001] The invention relates to a mixed coal water slurry fuel, in particular to a coal tar oil coal water slurry mixed fuel and a preparation method thereof. Background technique [0002] Coal water slurry is a new type of coal-based liquid fuel that emerged in the 1970s. It is made of about 65% coal, 34% water and 1% chemical additives. When the flame center temperature is low, the combustion efficiency is high, and the emissions of soot, SO2 and NOX are lower than those of fuel and coal. Based on long-term energy strategic considerations, many countries research, develop and reserve it as a fuel technology for replacing oil with coal, and it has been commercialized. [0003] my country's coal-water slurry research work started in the late 1970s and early 1980s, and it was in sync with foreign countries. The direct cause was the oil crisis that broke out in the world, and all countries were looking for a new energy to replace oil. And China is a country r...
