GB 40877-2021The norm of energy consumption per unit product of aluminium silicate wools and products (English PDF)

6.1.2 Classification

6.1.2.1 Aluminium silicate wools The energy consumption of aluminium silicate wools shall include the energy consumption of all production systems, auxiliary production systems and subsidiary production systems involved in the process from the raw materials entering the conveying and batching stage to the warehousing of cellucotton. The spinning process shall include: melting furnace, flow port, air compressor, fan, water pump, spinning, cotton collecting box mesh belt and dust removal. The injection process shall include: melting furnace, flow port, air compressor, fan, water pump, cotton collecting box mesh belt and dust removal.

6.1.2.2 Needled aluminium silicate wool blanket The energy consumption of needled aluminium silicate wool blanket shall include the energy consumption of all production systems, auxiliary production systems, and subsidiary production systems involved in the process from the cellucotton entering the needling stage to the warehousing of finished products, including: cooling fan, carpet roll, needle punch, dust removal, heating furnace (including electric heating and natural gas heating) and mesh belt.

6.1.2.3 Aluminium silicate wool wet-processed products (continuous mechanism) The energy consumption of aluminium silicate wool wet-processed products (continuous mechanism) shall include the energy consumption of all production systems, auxiliary production systems and subsidiary production systems involved in the process from the cellucotton entering the conveying and batching stage, to beating, slag removal, slurry preparation, storage, fourdrinier wire forming, and drying, cutting, to warehousing of the finished products.

6.1.2.4 Aluminium silicate wool wet-processed products (vacuum suction filtration) The energy consumption of aluminium silicate wool wet-processed products (vacuum suction filtration) shall include the energy consumption of all production systems, auxiliary production systems and subsidiary production systems involved in the process from the cellucotton entering the conveying and batching stage, to beating, slag removal, slurry preparation, vacuum suction filtration, and drying, cutting to warehousing of finished products.

6.2 Statistical method Use energy measuring instruments to measure and count the amount of energy consumption during the statistical period; do not recalculate or miss calculation. The energy measuring instruments shall comply with the relevant provisions of GB 17167 and GB/T 24851.

6.3 Calculation methods

6.3.1 Principle The calculation of the comprehensive energy consumption of aluminium silicate wools and products shall comply with the provisions of GB/T 2589 on the calculation principle and calculation range.

6.3.2 Calculation of comprehensive energy consumption of products The comprehensive energy consumption of aluminium silicate wools or products shall be calculated according to Formula (1): Where: E - the comprehensive energy consumption of a certain type of aluminium silicate wool or its products during the statistical period, in kilograms of standard coal (kgce); ei - the physical quantity of the ith energy (including the energy consumed by the energy-consumed medium) consumed in the production of a certain type of aluminium silicate wool or its products during the statistical period; ki - the conversion factor of the ith energy consumed in the production of a certain type of aluminium silicate wool or its products during the statistical period.
