Analysis of Thermal Efficiency of Furnaces Heated with Regenerative Burners
The method for determining the fuel utilization factor for furnaces, which are heated with regenerative burners that takes into account the overturn time, is proposed. Analysis of the influence of various factors on the value of the fuel utilization factor is carried out. The influence on this characteristics of the combustion products volume discharged from the furnace on valves overturn and the loss of physical heat with air blown from the layer into the waste products channel is quantitatively studied. It is shown, that the fuel utilization factor has a maximum at relatively small valve overturn times and then decreases slowly with time increase.
