Generally the Phosphate dozing is done in the drum of the boiler. it helps to convert the calcium hard salts to soft sludges. the sludges are higher in weight ,so it comes to the bottem of the drum . then it remove by CBD.
this is one of the way of avoiding corrosion in Boiler.

What is afbc boiler?
Atmospheric Fluidized Bed Combustion Boiler (AFBC boiler) is a type of operational boiler. In a AFBC boiler a little more fluidized bed combustor is added than a conventional shell boiler.
How do you lightup afbc boiler?
what is boiler
What are the Advantage and disadvantage of appointment books?
afbc
What is the advantage of afbc boiler over pf boiler?
afbc has high turn down ratio,burner arrangement is simple,low grade coal can be burnt efficiently,so2 emission can be controlled,
What is afbc boiler full form?
atmospheric fluidized bed combustion
What is the difference in Boiler efficiency between CFBC Boiler and PF Boiler while firing powdery coal -50 percent less than 5 mm size?
Cfbc stands for circulating fludised bed combustion where as afbc is for atmospheric fluidise bed combustion afbc bed fluidising velocity is approx 4 m/s and in cfbc boiler fluidising velocity is 9-10 m/s. cfbc having low SOx & NOx comparative with afbc cfbc having higher efficiency up to 98.5 % then afbc boiler,cfbc boiler power consumption is more comparative to afbc.
Differences between afbc and cfbc boilers?
(fbc) boiler to heat the Water that is mixed with a refractory material. With warming water temperatures will produce refractory materials that will ignite the oil in the water. The granular refractory materials are mixed with water. Refractory materials are heated in water to take it. c) boiler column. The steam comes out vertically. A) horizontal boiler. The steam comes out horizontally.
What is the composition of afbc bed meterials?
Silica 50-60% Alumina- 39% Fe2o3- 0.5% Tio2-0.5%
What has the author W Wayne Bowman written?
W. Wayne Bowman has written: 'The 160 MW AFBC Demonstration Project' -- subject(s): Fluidization, Fluidized-bed furnaces
How do you calculate coal consumption in afbc boiler?
how we calculate the coal consumed to generate xxx MW say 12 hrs or 24 hrs in CFBC boiler please help
