It is dangerous if the oxygen content in the two-stage gas generator is too high. When the oxygen content reaches a corresponding level, there may be a risk of explosion. Let’s analyze the reasons why the oxygen content in the furnace is too high:
1. Causes of too high oxygen: There is fire, slagging, wind tunnel or hot operation in the furnace, the saturation temperature is too small, the material layer is too thin, and the reaction is insufficient.
2、
Two-stage gas generatorReasons for excessively high carbon dioxide: the furnace outlet temperature is too high, cold operation occurs in the furnace, the saturation temperature is used too high, or the ash layer is low and the material layer is thin.
3. Reasons for high carbon content in ash and slag: the saturation temperature is too high, the temperature of the oxide layer is low, the furnace is in cold operation, the coal cannot be gasified, and the carbon content in the slag is high, partial furnace occurs, excessive ash production makes the ash layer too low, the load of the two-stage gas generator is greater than the specified gas production, etc., all lead to high carbon content in ash and slag.
