Katla projekt
The boiler with output of live steam 200 t. per hour is calculated in this
project. The temperature of live steam is 540 oC and the pressure in the drum 15
MPa. The temperature of the feedwater is 210 oC.
In this work I used the one grade economizer. The calculations are based on
the gas. The constitution of the fuel is: CH4=97.771; C2H6=0.862; C3H8=0.298;
C4H10=0.062; 2C4H10=0.052; N2=0.884; CO 2= 0.045; 2C5H12=0.013; n
C5H12=0.01; C6+=0.003. All these values are in percents. By the present output
the sharge of the fuel is 4,45 kg/s. The dimensions of the boiler are found
according to the capacity of the outgoing gases and size of the heating
surface.The dimensions of the boiler are: height 23.3 m; width 5.74 m and depth
5.6 m. I used 4 burners for the fuel combustion, which are placed into the front
side of the boiler
