A pharmaceutical company plans to install a solid fuel fired boiler for its daily usage. The desired capacity of the steam generation is 1.25 kg per second at pressure of 1.15 MPa and temperature 215oC. Feed water at average temperature of 25oC, is to be fetched from nearby reservoir. The consumption of the solid fuel having calorific value of 25.7 MJ/kg is 375 grams per second. Evaluate the enhancement of efficiency of the boiler

Question
A pharmaceutical company plans to install a solid fuel fired boiler for its daily usage. The desired capacity of the steam generation is 1.25 kg per second at pressure of 1.15 MPa and temperature 215oC. Feed water at average temperature of 25oC, is to be fetched from nearby reservoir. The consumption of the solid fuel having calorific value of 25.7 MJ/kg is 375 grams per second. Evaluate the enhancement of efficiency of the boiler if the following accessories are coupled with it. i) Economizer that increases the inlet feed water temperature by 63⁰C and reduces the fuel consumption by 18%. ii) Air-preheater that reduces the fuel consumption by 26%.
