example 1

[0018] Pour the starch and deionized water into the No. 1 beaker according to the mass ratio of 1:12, and move the beaker into a digital speed measuring constant temperature magnetic stirrer, and heat and stir for 4 hours at a temperature of 85°C and a speed of 600r / min. Finally, stop heating, cool down to room temperature naturally, then add graphene oxide with 0.5 times the starch mass into the No. 1 beaker, then stir and disperse at 1500r / min for 60min, and discharge to obtain a mixed dispersion; the volume ratio is 1: 1 Mix the obtained mixed dispersion liquid and oil phase into a three-necked flask, stir and emulsify at a high speed of 4000r / min with a stirrer for 60min, then move the three-necked flask into a water bath, and set the temperature at 75°C and the speed of 500r / min. Under constant temperature, stir and react for 5 hours. After the reaction is completed, transfer the material in the three-neck flask to a centrifuge, and centrifuge for 10 minutes at a speed of ...

Description

technical field [0001] The invention discloses a preparation method of a coal-saving synergist for boiler coal combustion, belonging to the technical field of energy conservation and environmental protection. Background technique [0002] The coal combustion effect is the coal-saving rate based on the integrated results 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. On the one hand, it is necessary to burn all the coal as much as possible, reduce the waste of coal caused by incomplete combustion, and pursue high combustion efficiency to generate more heat; High thermal efficiency for higher heat increase and coal saving effect. In actual production, it is a method to examine the combustion efficiency and thermal efficiency of coal combustion. The main factors affecting coal combustion efficiency are the combustion characteristics of various components s...
