C: specific heat kcal / (kg. °C)

M: mass kilogram △T

H: Time: hour.

2, the required power for flowing water and oil heating (regardless of container heat consumption) Kw=CF△T/14

C: specific heat kcal / (kg. °C)

M: flow rate kg / min △

T: temperature difference °C.

3. Channel type air heating (normal pressure) Kw=F△T/40

M: flow meter / minute

△T: temperature difference °C

40: coefficient kilowatts. cents (m / min)
