WATER-TUBE BOILER HEATING SURFACE CALCULATION
{हीटिंग सतह
गणना पानी ट्यूब बॉयलर}
1) Water tubes
2) DRUM
3) Downconvers tubes
4) Rises tubes
Calculation formula: Dia ×pi×Length
×Number of tubes
Water tubes Parameters [मापदंडों]
Water tubes = 150
Tube Dia meter = 100 mm
Length of tubes = 9 meter
(Pi) value ratio of the circumference of any circle approximately = 3.14
Dia × Pi × Length
Dia= 100mm converts to meter = 0.1
0.1×3.14×9
=2.826×150
423.9
DRUM
Calculation formula: Dia ×pi×Length
Dia = 1.2 meters
Length = 10 meters
Pi value= 3.14
Dia × pi × Lenth
1.2×3.14×10
37.68×1/2
18.84
DOWN CONVERS
Calculation formula: Dia ×pi×Length
Dia =
100mm convert to meter = 0.1
Length = 1.5 meter
Pi value= 3.14
Number of down convers tubes =10
Dia × pi × Length × number of tubes
0.1×3.14×1.5
0.471×10
4.71
Rises tubes
Calculation formula: Dia ×pi×Length
Dia = 100mm convert to meter = 0.1
Pi value = 3.14
Length = 10 meters
Number of tubes =10
Dia ×pi×Length× Number of
tubes
0.1×3.14×10
3.14×10
31.4
TOTAL HEATING SURFACE
423.9+18.84+4.71+31.4 =478.85
