Boiler Cycling Considerations - Babcock & Wilcox

Many fossil fuel-fired boilers are now experiencing load cycling or on/off cycling operation. These modes of operation involve cycling a unit on and off line or reducing loads to absolute minimums in response to varying load demand. This can be caused by daily or weekly load shifts experienced on nights and weekends, power generators dispatching units to the grid which utilize a lower cost

How to calculate cycles, blowdown, evaporation,

2005-9-9 · 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.) In SI metric units: M = Make-up water in m 3 /hr C = Circulating water in m 3 /hr

Boiler Operations & Boiler Maintenance | O&M |

Cycling a boiler on and off is very inefficient because there is a pre-ignition purge and a post-ignition purge that draw heat out of the boiler with each cycle. Also, in the case of a non-modulating boiler, cycling doesn't allow the boiler to operate at part load and steady

Cooling Tower Cycles of Concentration - AGI Water

2013-10-16 · If we start out with fresh water the tower has one cycle of concentration. When all the fresh water is evaporated ( solids are still in the tower) the tower then refills itself with more fresh water and we have twice the solids in the tower. We now have two cycles of concentration. This process will proceed and scale will form at a certain point.

Purified Tannins for Boiler Water Treatment - FCT

While tannins have been used for boiler water treatment for decades now, purified tannins are a proven technology that are quickly becoming the go-to choice for many businesses that rely on boilers. Purified tannin offers several advantages over both its non-purified counterpart, as well as over traditional boiler cleaning and treatment solutions like sulfites and phosphates.

Maintaining Cycles of Concentration - Boiler, Cooling

After examining what it means to "cycle up" water in a recirculating cooling tower system, last week our blog dealt with the system's Cycles of Concentration.Your water treatment specialist can help you determine what the maximum number of cycles is for your system. Once that is determined, the best method for maintaining this maximum number of cycles is an automatic control system that

Boiler modulation – is more better? - HPAC Magazine

2  · The benefits of boiler modulation are threefold; it reduces cycle losses, it reduces the wear on the components, and it can (but not necessarily as shown later in this article) result in higher thermal efficiencies. But aside from the benefits, what are the impacts of firing rate modulation on gas fired

Boiler feedwater - Wikipedia

2020-12-15 · 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

cycles of concentration – Water Technology Report

Cycles of concentration (C) = Makeup (MU) / Bleed (B) Cycles of concentration are also estimated by the ratio between specific conductance of the cooling water and the makeup water. From these relationships, the amount of bleed required to maintain a specific cycle of concentration is determined by: Bleed (B) = Evaporation (E) / (Cycles (C) – 1)
