The fuel-air ratio curve changes the amount of fuel and combustion air in direct proportion to the flow of water being sent to the coils. Dry steam is then produced in the steam separator where approximately ninety percent of the water is converted into steam. The water remaining is removed by a steam trap.

Boiler (power generation) - Wikiped

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

The first distilling plants that boiled a separate water supply from that of the main boiler, appeared around 1867. These were not directly heated by a flame, but had a primary steam circuit using main boiler steam through coils within a steam drum or evaporator. The distillate from this vessel then passed to an adjacent vessel, the distilling condenser.

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.
