根据我国一次能源以煤为主的政策,我国合成氨等化工产品绝大部分以煤为基础原料。煤气化成为制造合成气的龙头工序和关键技术,重要的设备造气炉以固定床间歇气化炉为主要角色。由于技术落后、产率低、能耗高、三废污染等,在当前经济建设和生产中必需进行技术改造、采用先进炉型,并兼顾联产,发展煤化工产品。本文介绍基本情况,列举技术改造和先进炉型,提出优选参照条例。
According to China’s primary energy-based coal-based policies, the vast majority of China’s chemical products such as ammonia based on coal-based raw materials. Coal gasification has become the leading process and key technology for the production of syngas. The major equipment for gasification furnaces is the fixed bed intermittent gasifier. Due to backward technology, low productivity, high energy consumption, three wastes and other pollution, in the current economic construction and production must be technological transformation, the use of advanced furnace, and take into account cogeneration, the development of coal chemical products. This article describes the basic situation, enumerate the technical transformation and advanced furnace, put forward the preferred reference regulations.
