Lower the actual boiler water level to the 1st low (by evaporation), and then blow down to the 2nd low. The main reason for this weekly test is to ensure that the alarm is given, and at the correct level, when the level drops slowly in the boiler (because floats could stick). 2. A high alarm is usually tested weekly.

Equivalent Evaporation | Advanced Steam Tracti

Equivalent evaporation actually indicates the amount of heat added in the boiler for steam generation. Equivalent evaporation refers to the quantity of dry saturated steam generated per unit of time from feedwater at 100°C to steam at 100°C at the saturation pressure corresponding to 100°C.

Evaporation Rate - an overview | ScienceDirect Topi

: 141KBTo generate high evaporation rate accompanied by high steam pressure, the fire-tube boiler becomes exorbitantly heavy; therefore, the size and weight become extremely difficult to manage. In regards to the size of the shell, these shortcomings are circumvented by passing flue gases outside the tubes, instead of inside, and water is circulated

Boiler Ratings | Spirax Sar

A boiler has a ‘from and at’ rating of 2 000 kg/h and operates at 15 bar g. The feedwater temperature is 68°C. The use of Equation 3.5.1 will determine a factor to produce the same result: Note: These values are all from steam tables. Using the information from Example 3.5.1 and the Equation 3.5.1 the evaporation factor can be calculated:

What is the effect of pressure and temperature on

Evaporation depends on temperature through vapor pressure of the liquid to be evaporated. A high temperature gives a high vapor pressure. At boiling temperature of 100 degree Celsius, vapor pressure of water is equal to 1 atmosphere. That means if
