Industrial Test of Energy Saving on Combustion of Watered Fuel Oil

摘要

A Self-made micro-mixing device was employed to produce watered fuel oil. Fuel oil and water in a certain ratio entered into the mixer through each channel respectively. Mixed with water fuel was formed under the action of shear force, convective impact and friction. The watered fuel oil was online applied to a steam boiler in an oilfield. The results of the industrial test show as follows: the thermal efficiency of the boiler was increased from 84.1% to 88.6% and the energy saving rate was 5.1% when the fuel oil was mixed with 3.49% water, meanwhile, CO emissions was decreased to 12.0×10^-6 from the previous 26.6×10^-6.
