In addition to the definitions of other clauses in G/T7332, this standard adopts the following definitions. 3.1 Thermal efficiency of heating equipment The thermal efficiency of heating equipment is the ratio of the effective energy required for heating equipment to the total energy obtained when the equipment is under load. 3.2 The load factor of heating equipment is the percentage of the output of heating equipment to the specified output. Usually expressed as the percentage of the output of the furnace and the micro furnace. 3.3 The utilization rate of heating equipment is the percentage of the annual working days of heating equipment. 3.4 The gas efficiency coefficient is the ratio of the actual supply air to the air required for complete combustion. 3.5 The energy for heat treatment refers to the fuel, solid and gas used as the initial heat source! And electricity, as well as the gas, wave fuel, etc. used to prepare the gas. 4 Ways to save energy in heat treatment
4.1 The energy saving of heat treatment can be magnified by the right technology and proper management. 4.2 Heat treatment heating equipment should be used continuously and work under nearly full load. 4.3 Reduce the heat of heating equipment and improve thermal efficiency: 4.4 Recycle the heat from burning, change the gas,
4.5 Provide energy-saving heat treatment technology under the most reasonable conditions: 4.6 Adopt energy-saving heat treatment process.
