Piping for the condensate drain was arranged to mix with the boiler blowdown
to neutralize the acidic discharge.
Examples include the use of a more stable boiler water dispersant, for higher cycles and less boiler blowdown
; or conversion to deposit control technology in recirculating cooling systems that tolerates higher dissolved solids, for less cooling tower blowdown, according to Johnston.
It is common to measure chloride at four points, the make-up, the feedwater, the boiler blowdown
line and the condensate.
A list of these additions to the Rankine cycle, which are discussed below, may include: 0, and C02, and CO and 02 management; boiler blowdown
automation; fuel oil viscosity control; Btu gas calorimeter monitoring; feed-water and condensate chemical control; and artificial intelligence diagnostics.
Regular boiler blowdown
is the obvious way to control contamination, although dosing the feed with chemicals such as ammonia or hydrazine also stops some chemicals getting that far.
Such a system should be able to incorporate a boiler blowdown
control loop to manage this variable as well.
It will include pretreatment of boiler water, the issues regarding the chemistry and what you need to know, the different water quality in areas of the country and how these differences affect the boiler, the quantity and use of appropriate chemicals, TDS levels, automatic monitoring, boiler blowdown
, condensate return, scale build up and efficiency as a result of poor treatment.
However, this ignores energy losses that can occur after the burner, such as scaled or dirty heat transfer surfaces or excessive boiler blowdown
There are two types of boiler blowdown
, each performing a different function.
The new RO system has reduced water and energy losses by cutting the amount of boiler blowdown
and water needed.
