Description
This dataset represents the consumable heat from district heating in Liaoning, China. The process accounts for the infrastructure, make-up water, energy consumption and heat losses required to deliver heat to heat users. Here, the infrastructure covers the heating pipe network comprising the primary network, heat substations and the secondary network; limited by data availability, the make-up water mainly considers the primary network and heat substation parts, and the power consumption for transmission and distribution mainly considers the heat substation part. The heat loss rate of the primary network directly adopts statistical data and is calculated on a weighted basis according to the proportions of heat sources from combined heat and power and regional boilers in the specific region; the heat loss rate of the secondary network is difficult to count accurately due to insufficient monitoring equipment, ambiguous heat loss boundaries, and incomplete data records and inconsistent statistical standards at the management level, and therefore the secondary network heat loss is not calculated separately.
Activity Description
The activity is realized through heat delivery via the heating pipe network.
Process Description
The product is heat in MJ, which is the sum of steam and hot water in energy terms. As an important energy product, heat is widely used in industrial production, building heating, domestic hot water supply and other fields in urban heating systems. Its essence is the form of thermal energy, which is transported and distributed through steam or hot water as a medium, and is ultimately measured and traded in terms of energy value.
