4 Waste heat classification
4.1 Classification by carrier
According to the carrier classification, it can be divided into. gas carrier waste heat, liquid carrier waste heat, solid carrier waste heat, mixed carrier waste heat.
Gaseous carrier waste heat. waste heat resources including flue gas, emitted steam, gas process logistics and non-combustible waste gas.
Liquid carrier waste heat. including waste heat resources of liquid products and liquid intermediate products, waste heat resources of condensate and cooling water, and combustible waste
Liquid waste heat resources.
Solid carrier waste heat. including waste heat resources of solid products and solid intermediate products, waste heat resources of slag discharge, and non-combustible solid waste
Waste heat resources.
Mixed carrier waste heat. refers to waste heat resources containing the above two forms or more.
4.2 Classification by grade
According to different carrier types, the temperature is taken as the apparent feature, and the technical economy of recycling is considered comprehensively, and the grade is divided. see
Table 1.
