Influence of the Length of a Torch Tongue on Heat Flow in a Burner Device

Abstract

Results of mathematical modeling of the burner torch of the furnaces of steam boilers with radiating cylindrical gas volumes are presented. As a result of modeling it is established that with a short torch tongue, the heat flows to the burner device can be significant and the service life of the burners reduced. By means of calculations it is established that with a 1.5 – 2-fold increase in the length of the torch tongue at constant power, heat flow decreases 2 – 3-fold in the burner device and the useful life of the latter increases to 10 years and more.
