苏联黑色冶金科学技术协会在1957~1958年间举行了关于开展大高炉高风温(到达1100—1200℃)热风炉的公开评选竞赛,结果选取了以下4种建议。(一)的建议:他建议用提高燃烧煤气的发热值的办法将风温提到1200℃。这可以通过使用混合煤气或预热空气和煤气的方法达到。根据他的计算用未预热的高炉煤气(发热值847kcal/Nm~3)燃烧温度只能达到1292℃,而要提高风温到1200℃需1500℃才行。因此他建议:
The Soviet Union’s Black Metallurgical Science and Technology Association held a public competition on hot stoves with large blast furnaces (reaching 1100-1200 ° C) between 1957 and 1958. As a result, the following four suggestions were selected. (A) suggestion: He suggested raising the calorific value of the combustion gas to bring the temperature to 1200 ° C. This can be achieved by using mixed gas or preheating air and gas. According to his calculations, the combustion temperature of blast furnace gas (calorific value 847 kcal / Nm ~ 3) can only reach 1292 ° C with no preheating, whereas 1500 ° C is required to raise the temperature to 1200 ° C. Therefore, he suggested:
