Description
This dataset represents the average situation of district boiler consumable heat in China. The process considers the infrastructure required for delivery to heat users, make-up water, energy consumption and the heat losses occurring during the process. Among these, the infrastructure covers the heat supply network consisting of 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 transmission and distribution electricity consumption mainly considers the heat substation part. The heat loss rate of the primary network directly adopts the average data from district boiler heat source statistics. The heat loss rate of the secondary network is not calculated separately, because it is difficult to accurately account for due to insufficient monitoring equipment, blurred heat loss boundaries, incomplete data records at the management level and non-uniform statistical standards.
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.
