Tenders are invited for provision of double stage evaporation system followed by solar evaporation pan for the
boiler blowdown and regeneration water at iocl lube blending plant tondiarpet chennai
Piping for the condensate drain was arranged to mix with the
boiler blowdown to neutralize the acidic discharge.
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.
A description of the work of this project can be summarized to include the installation of a new
boiler blowdown heat recovery system.
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 rates.
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.
By stripping out almost 99% of the dissolved solids, RO can reduce
boiler blowdown by an order of magnitude, resulting in significant savings in energy, water and treatment chemicals.
