The DCS issue in exhaust gases reduction
Thread Content
Under what conditions could DCS in exhaust gases explode? What conditions are required? How to solve it!
I’m not very knowledgeable, but here are my thoughts: 1. DCS tends to decompose at high temperatures; the gases produced, such as hydrogen, hydrogen chloride, and silica powder, are explosive, with hydrogen and silica powder being the most hazardous ones. 2. Have there been any explosions there? Generally, the exhaust temperature drops down by then. The explosion might have been caused by hydrogen leaking from the exhaust pipe. 3. At room temperature, DCS reacts violently with water, releasing a large amount of heat; the hydrogen gas generated may explode when in contact with air.
The exhaust gases that are produced as a result of this reduction process mainly consist of STC, DCS, TCS, and H2. These gases pass through an exhaust gas heat exchanger before reaching the CDI. As long as this mixture does not reach its explosive limit – in other words, as long as there is no leakage – no chemical explosion will occur.
1. Reaching the explosive limit range. 2. There is a source of fire or high temperature. 3. Mix with an oxidizing gas.
