T/CPCIF 0181-2022 Testing and Calculation Methods for Excess Heat Resources of Chemical Enterprises

Scope

Scope: This document specifies the classification, testing methods, and calculation requirements for waste heat resources in chemical enterprises. This document is applicable to the testing and calculation of waste heat resources in chemical production enterprises. Other enterprises may refer to it for implementation. Main technical content: 5.5 Testing methods 5.5.1 Testing methods for flue gas waste heat resources 5.5.1.1 The sampling and measurement methods for fuels shall be carried out in accordance with the provisions of GB/T 10180—2017, Sections 9.1 and 9.2. 5.5.1.2 The flue gas temperature testing methods are as follows: a) The measurement of flue gas medium temperature shall reasonably select thermocouple thermometers or resistance thermometers, and the temperature measurement points shall be arranged in relatively uniform temperature positions. b) The exhaust gas temperature shall be measured at multiple points. Generally, 2 to 3 measurement points can be arranged. The temperature measurement points shall be arranged in the cross-section of the pipeline or flue where the medium temperature is relatively uniform, and the arithmetic average value of the temperatures of all measurement points shall be taken as the exhaust gas temperature of the boiler and heating furnace. The temperature measurement points of the exhaust gas shall be arranged in the flue within 0.5 m to 1 m behind the last-stage heat-absorbing surface of the boiler and heating furnace. A pneumatic thermocouple shall be used. 5.5.1.3 The analysis of flue gas components can be measured using a flue gas analyzer. 5.5.1.4 The method of ash balance measurement shall comply with the provisions of GB/T 10180—2017, Section 9.12. 5.5.1.5 The method of determining steam humidity shall be carried out in accordance with the provisions of Appendix G of GB/T 10180—2017. 5.5.2 Testing methods for product and cooling medium waste heat resources 5.5.2.1 The testing methods for the temperature of oil, water,
