We have an endothermic gas generator, our question is how frequently should it be burned out?

Answer This will depend on what carbon potential you are running the generator at. Generally its carbon potential is approximatly 0.35% carbon. However, this can change with variations in the natural gas composition, and of course the air mix. It is generally better to control the generator with a three gas analyzer and to monitor the Carbon Monoxide, Carbon Dioxide and methane. You could go to a four gas analyzer and add nitrogen as a control gas along with the previously mentioned gases. The frequency of burn out should be (manufacturers recommendations) at once per week. However, it could be stretched out to once every two weeks. But do not let it slip beyond that.The burnout temperature is generally at approximatly 1500F(815C)
