A date and time (interval), shown in Danish time zone, where the values are valid. 00:00 o’clock is the first hour of a given day, interval 00:00 - 00:59, and 01:00 covers the second hour period (interval) of the day and so forth.

Comment

On one normal day there will be 24 intervals.

When daylight saving times shifts there will be either 23 or 25 intervals.

Please note that the format shown in the example applies to data download as JSON, XML or fetched through the API and is in accordance with the ISO 8601 standard. The format is slightly different when it is shown on screen or downloaded manually as CSV or XLSX. This is mainly due to readability and consideration for Excel users.

In preview (in the GUI) all timestamps are shown as (display convention) YYYY-MM-DD hh:mm e.g. 2017-07-14 08:00. Please note that is no time zone indicator, showning that this is local (Danish) time.

In download (CSV and XLSX) the date time are exported as YYYY-MM-DD hh:mm e.g. 2017-07-14 08:00. That is without the “T” and the seconds. Excel will recognize it as date-time. The user must remember that this is local (Danish) time.

In download (JSON and XML) the format used is YYYY-MM-DDThh:mm e.g. 2017-07-14T08:00.

Gross Calorific Value

Name Gross Calorific Value
Description

A term describing the amount of heat developed by combustion of one cubic metre of gas at constant pressure when the gas and air for the combustion have a temperature of 25°C, the combustion products being brought to that temperature and the water formed by the combustion being present in liquid state. The reference conditions for normal cubic metres are 0°C and 1 atm.

Wobbe Index

Name Wobbe Index
Description

The Wobbe index offers information about the heating effect a burner is exposed to during combustion of a fuel. The greater the Wobbe index, the greater the heating effect and thereby the greater the load on the burner. The load on a burner is thus directly proportional to the Wobbe index. Different gases with the same Wobbe index will impose the same load on the burner.

Methane Number

Name Methane Number
Description

A methane number characterises the gas's knock tendency as a fuel for gas engines. It can be compared to the octane number for petrol.

Comment

Per definition pure methane has a methane number of 100 and pure hydrogen a methane number of 0. A content of higher hydrocarbons than methane reduces the methane number while the CO2 content increases the methane number.
