Since boiler blowdown (BD) is expressed as a percentage of the total feedwater (and is calculated as the re-ciprocal of the number of times the feed-water can be concentrated), the more the feedwater can cycle in the boiler, the less blowdown is needed. This is
Boiler feedwater - Wikiped
2019-9-7·Boiler feedwater is an essential part of boiler operations. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used it is then dumped to the main condenser. From the condenser it is then pumped to the deaerated feed tank. From this tank it
US5041386A - Concentration cycles, percent lif
Concentration cycles, percent life holding time for a component in the boiler and continuous treatment concentrations are monitored or determined in a boiler system by adding to the feedwater an inert tracer in a predetermined concentration C I, which reaches a final concentration C F at steady state in the boiler and which exhibits a blowdown concentration C t at different points in time.
How to calculate cycles, blowdown, evaporation
Concentration cycles in petroleum refinery cooling towers usually range from 3 to 7. In some large power plants, the cooling tower concentration cycles may be much higher. (Note: Draw-off and blowdown are synonymous. Windage and drift are also synonymous.). Back to Chemical process engineering FAQ Index Back to Chemical process engineering Forum
COC - Cycle of concentration in cooling water syst
Cycles of Concentration in Cooling Water COC. What is COC ? COC or the Cycles Of Concentration is an abbreviation, used when talking about cooling water or cooling tower water. The COC specifies, how often a fresh water added into the loop, can be used or pumped around, before the water has to blown down or bleed off from the cooling tower
Boiler water consumption - lenntech.c
b = boiler water TDS concentration. m = make-up water TDS concentration. r = fractional condensate return. This ratio can be optimized by controlling the boiler make-up water (click in new page) quality and the reused boiler blowdown (click in new page) quality. Boiler water quality shall be set according to the boiler pressure and type of heater.
Cooling Tower Water Treatment Cycles o
Cycles of Concentration. An important concept related to Cooling Towers is the Cycles of Concentration (also known as Cycles or Concentration Ratio). Cycles of Concentration is monitored with a conductivity meter and it is a measure of the concentration of dissolved solids in the Cooling Tower process water.
