hot air generator
(OP)
iam working in a vacum salt plant and we need to generate hot air through multi stage heat exchanger between air from a blower and heat from direct flame using a burner
i want to decide what burner i should use so i need to know how i can calculate the heat needed to heat 154 metre cubic per minute of air from 25 degree to 150 degree at normal pressure
tanks

Consider environmental pollution. Consulting with experts such as in

Just an idea.

RE: hot air generator
First you need to convert the volume flow to a mass flow (lb/hr or Kg/hr). In metric units the density should be on the order of 1.2 kg/m^3. The actual density may be slightly more or less than this, depending on what temperature you use for the volume flow.
The specific heat of are is approx. .24 Kcal/(Kg-Deg C)
Now you can simply multiply the the three factors together to get the heat load:
Q = M X Cp X (delta T)
