A steam generator operating at steady state use methane gas (CH4) with 140% theoretical air as the fuel. Methane enters the combustion chamber at 25°C, 1 atm and air enters at 127°C, 1 atm. The products of combustion exit at 427°C, 1 atm. In a separate stream, saturated liquid water enters at 8 MPa and exits as a superheated vapour at 480°C with negligible pressure drop. If the vapour mass flow rate is 3.75 x 10° kg/h, calculate the flow rate of the methane in kmol/h.

Question

What is the flow rate?

A steam generator operating at steady state use methane gas (CH4) with 140% theoretical air as the fuel. Methane enters the combustion chamber 1. (а) at 25°C, 1 atm and air enters at 127°C, 1 atm. The products of combustion exit at 427°C, 1 atm. In a separate stream, saturated liquid water enters at 8 MPa and exits as a superheated vapour at 480°C with negligible pressure drop. If the vapour mass flow rate is 3.75 x 10° kg/h, calculate the flow rate of the methane in kmol/h.
