1 ton is about 1000 kg
Assuming water is already at 100 C (hot water that just has to boil)
it takes 40.7 KJ of energy to convert 1 mole of water to steam
1 cal = 4.184 J
1 mole water = 18 grams
4.5 x 106 cal per what mass of coal?? again I'll assume 1 ton of coal.
(1 ton Steam) x (1000 kg/ton) x (1000g/kg) = 1 x 106 grams
(1 ton water)x(106grams/ton)x(1mole/18grams)x(40.7x103 J/mole)x(1 cal/4.184J) = E
Where E represents the energy to vaporize 1 ton water measured in cal.
now divide this answer by the 4.5x106 cal/(ton??)
this will give the mass of coal needed assuming no heat loss to the environment.
It depends on how long you are prepared to wait!
It depends on the calorific value of the fuel.
6,520 Btus
Assuming standard atmospheric pressure, 2260 kilojoules.
You mean how much heat energy will be lost/transferred as you are losing Joules here. All in steam, so a simple q problem and no change of state. 2.67 kg = 2670 grams q = (2670 grams steam)(2.0 J/gC)(105 C - 282 C) = - 9.45 X 105 Joules ----------------------------------- This much heat energy must be lost to lower the temperature of the steam.
How much steam is required to produce 5 MW power in steam turbine?In fully condensing turbine we will need 20 TPH steam required to generate for 5MW
3.5 ton steam
If by dry steam you mean superheated steam then dry steam because it has a higher calorific value
It depends on how long you are prepared to wait!
To calcualte NCV you need calorific value on GAR, H on gar and Total moisture.
As a rule of thumb you would need about 138 Kg of coal (26GJ/Ton) to produce 1 ton of steam.
It depends on the calorific value of the fuel.
Steam boilers work by boiling water to generate steam. The steam then is used to heat the engine.
steam is used to generate electricity. what happens to the steam after it has generated electricity?
There are boilers designed to heat mineral oil (as well as other fluids) which is then pumped through a heat exchanger to generate steam.
Nuclear power is used to create large amounts of heat which generate steam. Basically, the steam is then used to spin steam turbines attached to generator sets, which generate power.
The lower calorific value or Net calorific value (NCV) which supposes that the products of combustion contain the water of combustion to the vapor state. The heat contained in this water is not recovered.The higher calorific value or Gross calorific value (GCV) which supposes that the water of combustion is entirely condensed. The heat contained in this water is recovered.sayed karar waris
