Mr Manova,

 From what I can understand, your problems you faced are related to 
running the gasifier at twice its capacity, and not due to increased 

Originally the pressure at the burner was 150 mmWC & not the rated 600 
mmWC. This means the gas flow is about 50% of the rated flow.

You will have to use a gasifier of double the existing capacity to 
overcome your problems.

To get the desd flow, you increased
