EFFICIENCY AND CAPACITY OF BOILERS - Project Gutenberg

In a single boiler it may be accomplished by discharging steam through a waste pipe and regulating the amount by means of a valve. In a battery of boilers in which only one is tested the draft may be regulated on the remaining boilers to meet the varying demands for steam leaving the test boiler to work under a steady rate of evaporation. 6.

Evaporation Rates Condensation Rates and Relative ...

Meanwhile temperature controls evaporation rates (higher temperatures yield higher evaporation rates) so relative humidity depends on dew point (which reflects the amount of water vapor present) and temperature. I should point out however that we can't just substitute dew point and temperature into the equation for relative humidity above ...

How Much Evaporation Does Large Boiler Mean

Evaporation ratio = quantity of steam generation/quantity of fuel consumed.For example quantity of steam Is 310 ton/hr and fuel is 55 ton/hr then the evaporation ratio is 5.63. Evaporation ratio is also known as steam fuel ratio.A drop in evaporation ratio indicates drop in boiler efficiency.Boiler evaporation ratio depends on fuel quality.
