The saturation temperature of steam with increase in pressure increases
Coke is produced by
Coke. It is produced when coal is strongly heated continuously for 42 to 48 hours in the absence of air in a closed vessel. This process is known as carbonisation of coal. Coke is dull black in colour, porous and smokeless. It has a high carbon content (85 to 90%) and has a higher calorific value than coal.
Heating of dry stream above saturation temperature is known as
One kg of steam sample contains 0.8 kg dry steam; it's dryness fraction is
The specific heat of superheated steam in kcal/ kg is generally of the order of
On Mollier chart, flow through turbine is represented by
The bituminous coal is non-caking if its carbon content is
Alkaline pyrogallate is used in Orsat's apparatus or absorption of
Efficiency of ranking cycle can be increased by
Increasing the operating pressure of the boiler, automatically raises the temperature at which boiling takes place. This raises the average temperature at which heat is added to the steam and thus raises the thermal efficiency of the cycle.
The following boiler makes use of pressurized combustion
