Description

The consideration of the introduction of biofuel and the enlargement of the calorific value of gas in the main gas distribution contributes to disturbances in the atmosphere of the furnace. In such conditions, the use of an expensive Wobbe meter is a solution. However, the introduction of a controlled loop of the atmosphere combined with the automatic adjustment of the air/gas ratio may solve the problem. On top of this, the configuration allows for stablilization of the composition of the atmosphere in the furnace if any variation of the production occurs.
