heat transfer coefficient of flue gases industrial boilers

Heat Exchangers in Boilers - Energiteknik | KTH

2003-10-30·Heat transfer surfaces The primary elements of a boiler are the heat transfer surfaces, which transfer the heat from the flue gases to the water/steam circulation. The objective of the boiler designer is to optimize thermal efficiency and economic investment by arranging the heat transfer surfaces and the fuel-burning equipment.

It is used in calculating the heat transfer, typically by convection or phase transition between a fluid and a solid. The heat transfer coefficient has SI units in watts per squared meter kelvin: W/(m 2 K). Heat transfer coefficient is the inverse of thermal insulance. This is used for building materials (R-value) and for clothing insulation.

2012-2-9·As shown in the schematic, the dry stoichiometric flue gas flow rate (m3/s) is obtained by multiplying the heat release (MW) by a fuel factor (m3/MJ). The heat release can be obtained directly, from the plant thermal input (fuel flow * net calorific value), or indirectly, from the power output divided by the thermal efficiency.
