Boiler Blowdown Rate

A blowdown of the boiler is a routine operation necessary due to the increased concentration of Total Dissolved Solids - TDS - in the boiler during the steam production. The blowdown rate of a boiler depends on: steam consumption (steam used in the process and not returned as condensate to the boiler), concentration of impurities in the feed water, maximum allowable TDS in the boiler.

Boiler Percent Condensate Return

The percentage of condensed steam that is returned to the boiler.

Burner Turndown Ratio

If applicable, the turndown ratio for the burner (full input/minimum input).

View None
Burner Type

Type of burner on boiler or furnace, if applicable.

View None
Cell Control Type

Cooling tower cell control type. A cooling tower cell is the smallest tower subdivision bounded by either exterior walls or partition walls, which can function as an independent unit with regard to air and water flowMost larger cooling tower systems use a multiple-cell configuration. This configuration allows for the correct staging of equipment as the facility loads vary and incorporate redundancies such that critical operations are never in jeopardy of being nonoperational.

View None
Cell Count

The number of cells in the cooling tower. Each cell has its own fan, water flow allowing for responding to lower load conditions

Chiller Compressor Driver

Equipment driving the compressor used in a chiller

View None
Chiller Compressor Type

Type of compressor in the chiller.

View None
Compressor Staging

The compressor staging for the unit. Select "Single Stage" for units with single stage (on/off) control. Select "Multiple, Discrete Stages" for units with multiple compressors, discrete unloading stages, or compressors with stepped speed motors that are controlled to operate at discrete stages. Select "Variable" for compressors that operate at variable speeds or with modulating unloading.

View None
Condenser Fan Speed Operation

The condenser fan control option used by the unit. If the unit has several constant-speed condenser fans that stage on in conjunction with multiple compressors, this should be set to ÒStepped Speed.Ó

View None
Condenser Type

Type of condenser used for DX cooling plant.

View None
Condensing Operation

Capability of a boiler or furnace of condensing the water vapor in the exhaust flue gas to obtain a higher efficiency.
