Research on the Atomization Characteristics of UCMCWS──A Novel Diesel Oil Substitute

Ultra-Clean Micronized Coal Water Slurry (UCMCWS ) as a form or coal-based fuel can be used in place of oil in diesel engine, gas turbine and clean combustion. In laboratory UCMCWS has been made from ultra-clean coal with ash less than 0. 8%, with concentration of UCMCWS less than 55%, and with viscosity less than 600 mPa. s. A test rig of atomization with diesel oil nozzle has been made. A preliminary conclusion is that UCMCWS can be atomized as good as diesel oil in the working condition of diesel engine.

Life Cycle Assessment of Ultra-clean Micronized Coal Oil Water Slurry

Life cycle assessment is applied to assess the ultra-clean micronized coal oil water slurry (UCMCOWS) with SimaPro and the environmental impact of UCMCOWS on its whole life cycle is also analyzed. The result shows that the consumption of energy and products are increasing along with the deepening of UCMCOWS processing, UCMCOWS making and combustion are the two periods which have a bigger impact on eco-system and human health. As a new substitute of fuel, UCMCOWS merits to be utilized more efficiently and reasonably.
