A boiler is a closed vessel in which water or other fluid is heated. The fluid does not necessarily boil. Boilers
Слайд 2A boiler is a closed vessel in which water or other
fluid is heated. The fluid does not necessarily boil.
Boilers
Слайд 3The heated or vaporized fluid exits the boiler for use in
various processes or heating applications,[1][2] including water heating, central heating, boiler-based power generation, cooking, and sanitation.
Слайд 5Boiler efficiency
there are two method to measure the boiler
efficiency
1) direct method
2) indirect method
1) direct method
2) indirect method
Слайд 6Direct method
Direct method of boiler efficiency test is more usable or
more common
ККД котла = Q * (Hg-Hf) / д * GCV * 100
ККД котла = Q * (Hg-Hf) / д * GCV * 100
Слайд 7Indirect method
to measure the boiler efficiency in indirect method we need
a following parameter like
1)Ultimate analysis of fuel (H2,S2,S,C moisture constraint,ash constraint)
2)percentage of O2 or CO2 at flue gas
3)flue gas temperature at outlet
4)ambient temperature in deg c and humidity of air in kg/kg 5)GCV of flue in Kcal/kg
6)ash percentage in combustible fuel
7)GCV of ash in Kcal/kg
