Abstract

A composite sulfur-curing agent consists of lime powder, industrial cinder and micro-silicon powder. It's cheap and efficient, has less sulfur dioxide, acid rain and no environmental pollution.

Description

technical field [0001] The invention relates to a novel composite sulfur-fixing agent, which is specifically used for reducing excessive sulfur dioxide gas released during the combustion process of a coal-fired boiler, so as to reduce atmospheric acid rain and protect the environment. Background technique [0002] In my country's coal consumption, about 85% of coal is directly used for combustion as thermal coal. Every year, about 2,500 tons of sulfur dioxide are emitted from coal combustion, causing serious sulfur dioxide pollution and acid rain pollution. Adding a sulfur-fixing agent to the coal combustion, so that the sulfur dioxide released during the coal combustion process reacts with the sulfur-fixing agent to form a stable solid solution substance, thereby reducing the sulfur dioxide content in the exhaust flue gas. Because of its simple operation, it is easy to implement Low cost and widely used. However, due to the high cost of sulfur fixation agent, or the incon...
