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.

kg/hr
Boiler Insulation R Value

Insulation R-Value of hot water storage tank.

hr-ft2-F/Btu
Boiler Insulation Thickness

Insulation thickness of hot water storage tank. [inches]

Boiler Percent Condensate Return

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

percent
Burner Turndown Ratio

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

None
Burner Type

Type of burner on boiler or furnace, if applicable.

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

count
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.

View None
Cooling Delivery Type

Method of delivering cooling to the zone.

View None
Cooling Medium

Medium used to transport cooling energy from a central cooling system to individual zones.

View None
Cooling Stage Capacity

Average capacity of each cooling stage, at ARI rated conditions, expressed as a fraction of total capacity

None
Cooling Type

Source of cooling. Cooling delivery is recorded in a separate data field. Use of fans or blowers by themselves without chilled air or water is not included in this definition of cooling. Stand-alone dehumidifiers are also not included.
