Those who give correct answers will receive an additional 4 wealth points as a bonus. The time frame for responding is 24 hours; after that, this post will be closed. We encourage everyone to participate actively, and those who can provide detailed explanations of the relevant knowledge will receive extra rewards. 7.4 To reduce the heat consumption in coking, which of the following measures can be taken? () A. Maintain the minimum possible center temperature of the coke cake, while ensuring good coke quality. B. Reduce the moisture content of the coal used in blending. C. Select an appropriate value for α. D. Improve the insulation properties of the furnace and maintain a stable heating regime. Correct answer: ABCD. Note: This is a multiple-choice question from the Coalification Section Management Team
A: While ensuring the quality of coke, the lowest possible center temperature of the coke cake is adopted. I believe this merely serves to reduce the amount of gas used; if too much gas is used it is wasted, while if too little is used the gas is not fully utilized. Therefore, it cannot be considered a reduction in energy consumption. C. Selecting the appropriate α value – this is to ensure complete combustion of the gas, but it doesn’t really fall under that category either. . . D. Improving the thermal insulation of the furnace body and controlling a stable heating regime – this is feasible.
The following measures ABCD can be taken
7.4 To reduce the heat consumption in coking, the following measures can be taken: (c) A. Maintain the quality of coke while using the lowest possible temperature at the center of the coke cake; B. Reduce the moisture content of the coal used in blending; C. Select an appropriate value for α; D. Improve the insulation properties of the furnace and maintain a stable heating regime
My correct answer is ABCD; if I’m wrong, it’s just part of learning.
