*Objective: *
We have to heat the 20bar compressed air from 25C to 300C.
*Data: *
Air inlet temp=25C
Air pressure =20bar
Air flow rate = 14kg/s
Air need to be heated to 300C.
Heat load required is approximately *4MW*
*Solution: *
There are two options
1) 02 X furnace or kerosene fired boilers, each of 2MW capacity, which can directly heat the air from 25C to 300C
2) 02 X furnace or kerosene fired boilers, each of 2MW capacity, heat the thermal oil and then heated oil goes to the heat exchanger where it ultimately heats the air from 25C to 300C.
It is requested to kindly ask your technical team to evaluate these options. Kindly cross check the heat load requirements i. e 4MW
