To calculate the %heat loss from openings in furnace, five essential parameters are needed and these parameters are <strong>Black Body Radiation (B<sub>R<\/sub>), Emissivity (E), Radiation Factor (R<sub>F<\/sub>), Quantity of Oil (Q)<\/strong> and<strong> Gross Calorific Value of Oil (GCV<sub>oil<\/sub>).<\/strong><\/p>\n<h3><strong>The formula for calculating %heat loss from openings in furnace:<\/strong><\/h3>\n<p>%Q<sub>L<\/sub>\u00a0= 100(<sup>B<sub>R<\/sub>\u00a0x E x R<sub>F<\/sub><\/sup>\/<sub>Q x GCVoil<\/sub>)<\/p>\n<p>Where:<\/p>\n<p>%Q<sub>L<\/sub>\u00a0= %Heat Loss from Openings in Furnace<br \/>\nB<sub>R<\/sub>\u00a0= Black Body Radiation<br \/>\nE = Emissivity<br \/>\nR<sub>F<\/sub>\u00a0= Radiation Factor<br \/>\nQ = Quantity of Oil<br \/>\nGCV<sub>oil<\/sub>\u00a0= Gross Calorific Value of Oil<\/p>\n<p>Let&#8217;s solve an example;<br \/>\nFind the %heat loss from openings in furnace when the black body radiation is 15, the emissivity is 6, the radiation factor is 3, the quantity of oil is 24 and the gross calorific value of oil is 9.<\/p>\n<p>This implies that;<\/p>\n<p>B<sub>R<\/sub> = Black Body Radiation = 15<br \/>\nE = Emissivity = 6<br \/>\nR<sub>F<\/sub> = Radiation Factor = 3<br \/>\nQ = Quantity of Oil = 24<br \/>\nGCV<sub>oil<\/sub> = Gross Calorific Value of Oil = 9<\/p>\n<p>%Q<sub>L<\/sub>\u00a0= 100(<sup>B<sub>R<\/sub>\u00a0x E x R<sub>F<\/sub><\/sup>\/<sub>Q x GCVoil<\/sub>)<br \/>\n%Q<sub>L<\/sub>\u00a0= 100(<sup>15 x 6 x 3<\/sup>\/<sub>24 x 9<\/sub>)<br \/>\nSo, %Q<sub>L<\/sub>\u00a0= 100(<sup>270<\/sup>\/<sub>216<\/sub>)<br \/>\n%Q<sub>L<\/sub> = 100(1.25)<br \/>\n%Q<sub>L<\/sub> = 125<\/p>\n<p>Therefore, the\u00a0<strong>%heat loss from openings in furnace\u00a0<\/strong>is\u00a0<strong>125%.<\/strong><\/p>\n<p>Read more:\u00a0<a
