Answer / anand swami

u can calculate it by this formula
P1 V1 / T1 = P2 V2 / T2
Where for normal condition pressure is 1 atm and temp
273 k and v1 is known so volume in m3 at any temp T2 and
ppressure P2 we can calculate

Answer / gopal singh

to convert nm3 to m3 require standard temperature.
suppose st.temp=30'c
then m3= 273+30/273X(nm3).

Answer / c.sudhir

Generally the aiAir to fuel ratio will be 1.3.5 , so t
based on the calarafic value of the Fuel the Air ratio is
maintained , so iam here by writing the calcualation part
with Example .
GENERAL CALCULATION

1. Specific steam should be produced per kg of
briquette.
= …………CV…(Calorific value of
Briquette.)…………
Specific Fuel Enthalpy –
Feed water temperature ( or Enthalpy of Feed water )

Exp: = 4200 KCAL/ KG (BRIQUETTS)
(663-62)

= 6.9 kg of steam / Kg of briquette

1kg of briquette = 6.9kg of steam

2. Specific Fuel consumption per actual
Briquett Burned.

= TOTAL STEAM
PRODUCED
TOTAL
BRIQUETTS CONSUMED (OR)

= TOTAL WATER
CONSUMED
TOTAL
BRIQUETTS COMSUMED

Exp: = 13094KG = 3.2 hs of
STEAM
4186 hs

= 17540 Kg = 4.1kg /STEAM
4186kg

Efficiency of Boiler = Actual /
Standard = 4.1/6.9= 0.59x100= 59%

ACTUAL CALCULATION

= STEAM GENERATED (SP ENTHALPY OF STEAM AT Std
Pressure – FEED WATER Temp
CALALARAFIC VAIVE * FUEL CONSUMED (S.F.C)

ExP: = 13094 ( 663-62) = 0.448100 =44%
4200 *4186Reg.,
