Physics Forums require the poster to show some effort, by at least articulating what is happening physically.
Homework Statement
Dry saturated steam at a temperature of 180ºC is to be produced in a fire tube boiler from cooling of 50000 kg/h of flue gases from a pressurised combustion process. The gases enter the tubes of the boiler at 1500ºC and leave at 100ºC. The feed water is externally preheated to 180ºC before entering the boiler.
The mean specific heat capacity of the flue gases is 1.15 kJ/kgK. The latent heat of vaporisation of the water at 180ºC is 2015 kJ/kg. Feed water temperature = 180ºC.
Determine the amount of steam produced per hour, if the total heat loss is 10% of the heat available for steam raising.
Don't even know where to begin with this so any advise to get me started would be extremely grateful as I am completely lost at the moment.
Many thanks in advance...
