Feb 05, 2020 · For pulverized coal fired boilers burning bituminous coal, the value of ψ generally can be prescribed as 0.65. The correlation equations for the tube bank convective heat transfer coefficient h f and the recommended values for ψ are widely available in heat transfer text books and open literatures. These correlation equations can be easily implemented into the CFD code by means of UDFs for each …

Boiler type Heat loss per heat input of fuel Oil fired boiler 0,2 - 0,5 % Coal fired boiler, dry ash removal 3% Coal fired boiler, molten ash removal about 2 % Grate boiler 4-6 % Heat loss due to wasted heat in flue gases Flue gases leave the furnace in high temperature and thus they carry significant amount of energy away from boiler process.
