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.

Geography comment
This data set represents the consumable heat for district heating in Tianjin, China, taking into account the infrastructure required for delivery to heat users, water replenishment, energy consumption, and heat losses in the process. Among them, the infrastructure covers the heating pipe network composed of primary pipe network, thermal station and secondary pipe network; due to the limitation of data availability, the amount of water replenishment mainly considers the primary pipe network and thermal station part, and the power transmission and distribution consumption mainly considers the thermal station part. The heat loss rate of the primary pipe network directly uses statistical data and is weighted based on the proportion of heat sources in specific regional cogeneration and regional boilers. The heat loss rate of the secondary pipe network is difficult to accurately count due to insufficient monitoring equipment, fuzzy boundaries of heat loss, incomplete data records at the management level, and inconsistent statistical standards. Therefore, the heat loss of the secondary pipe network is not calculated separately.
