TY - JOUR TI - Reliable simple zonal method of the furnace thermal calculation AU - Ivanović Vladan JN - Thermal Science PY - 2005 VL - 9 IS - 2 SP - 44 EP - 55 PT - Article AB - The calculation of the furnace in the industrial and power boilers is the most important and the most responsible part of the thermal calculation, and it has important influence on the rationalization of energy consumption. In the paper one-dimensional zonal method of the furnace thermal calculation of steam boilers is presented. It can successfully define disposition of flue gas temperature and specific thermal load of screen walls with height of the furnace in case of uneven deposits distribution which vary in size and quality. Its greatest use is for comparing furnace performance under various operating conditions.
