Description
This dataset represents the average situation of recovering industrial waste heat for heat supply from typical industrial enterprises in China. The core of its production process is to recover the thermal energy originally discarded in industrial production, transferring heat to a clean circulating medium through a heat exchange device, producing steam or hot water that can be used for heat supply. The inventory data are the result of merging multi-source data, obtained by heat-supply-weighted averaging of the waste heat resources of representative steel plants (such as waste heat from coking and sintering processes) and chemical plants (such as process reaction heat). The data are mainly sourced from official survey reports.
Activity Description
The system boundary covers the thermal mixing produced by multiple industrial waste heat technologies within a specific area without an actual thermal mixing point.
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.

Technology comment
Industrial waste heat heating refers to a method of inputting electricity or other high-grade heat and recovering waste heat generated during industrial production as a heat source. The core process includes: natural gas is transported to the boiler combustion chamber through pressure regulation for combustion, which directly converts chemical energy into thermal energy, converts the water in the boiler into steam or high-temperature hot water, and finally produces heat measured in energy. The flue gas produced by combustion is purified using selective catalytic reduction and denitrification technology before being emitted.
