The feedwater temperature might be stated in the boiler design assignment. If it is not given, it should be chosen from the range of 200-250 °C. The mass flow rate before the economizer is the blowdown mass flow rate added to the mass flow rate from the steam drum to the superheaters.

Waste heat recovery boiler uses waste flue gases for steam production, so this economizer is also work on these varying parameters like gas flow rate, temperature variation, pressure variation, amount of ash content in flue gases. By considering these parameters we are going to design the economizer for waste heat recovery boiler.

analyses. The calculated flue gas flow is compared with the reference flue gas flow calculated from the elemental composition. It is shown that, for a wide range of coal and biomass compositions, the above formula performs very well. For light fuel oil the formula is: V God = 1.76435 + 0.20060 H (N) (m 3/kg) and for natural gas: V God
