example 1

[0018] Pour starch and deionized water into the No. 1 beaker according to the mass ratio of 1:12, and move the beaker into the digital display speed measuring constant temperature magnetic stirrer, at a temperature of 85 ℃, rotating speed 600r / min conditions, heating and stirring for 4h After that, stop heating and cool to room temperature naturally, then add graphene oxide 0.5 times the starch mass into the No. 1 beaker, then stir and disperse at 1500r / min for 60min, discharge, and obtain a mixed dispersion; the volume ratio is 1: 1 Pour the obtained mixed dispersion and oil phase into a three-necked flask, stir and emulsify at a high speed of 4000r / min with a stirrer for 60 minutes, then move the three-necked flask into a water bath at a temperature of 75℃ and a rotating speed of 500r / min. After the reaction was completed, the contents of the three-necked flask were transferred to a centrifuge and centrifuged for 10 minutes at a speed of 15000r / min. The lower layer sediment wa...

Description

Technical field [0001] The invention discloses a preparation method of a coal-saving synergist for boiler coal combustion, which belongs to the technical field of energy saving and environmental protection. Background technique [0002] The coal combustion effect is the integration result of the combustion efficiency of whether the coal is completely burned, and the thermal efficiency of whether the heat generated by the burned coal is fully utilized, and is concentrated as the coal saving rate. On the one hand, we must try to burn all the coal, reduce the loss of coal waste caused by incomplete combustion, and pursue high combustion efficiency to generate more heat; on the other hand, we must try our best to reduce the heat loss during the conduction heating process. High thermal efficiency to obtain higher heat-increasing and coal-saving effects. A method of investigating the efficiency of coal combustion and thermal efficiency in actual production. The main factors that affe...
