去年11月下旬我们天津市粉煤灰综合利用考察组一行4人,应日本国际贸易促进会关西本部的邀请,赴日本考察参观了人造轻骨料工厂。日本国土不大,煤的储量很少,所有以往发电厂的燃料均烧重油。世界石油危机发生后,日本的能源结构逐渐发生变化,发电厂以煤作为燃料逐渐多起来。为此近几年日本逐渐对粉煤灰的综合利用提到了议事日程上来。
In late November of last year, our four-person inspection group for comprehensive utilization of fly ash in Tianjin was invited to visit the man-made lightweight aggregate plant in Japan at the invitation of the Kansai headquarters of the Japan International Trade Promotion Association. Japan is a small country with little coal reserves. All previous power plant fuels burn heavy oil. After the world oil crisis, Japan’s energy structure gradually changed, and power plants gradually increased with coal as fuel. For this reason, Japan has gradually mentioned the comprehensive utilization of fly ash on the agenda in recent years.
