Announcement by the General Administration of Quality Supervision, Inspection and Quarantine on the Issuance of Amendment No. 1 to the \"Regulations on the Supervision and Management of Energy-Saving Technologies for Boilers\" (No. 113, 2016)

Thread Content

Based on the implementation of the safety technical specifications for special equipment, the General Administration of Quality Supervision, Inspection and Quarantine has amended certain provisions of the \"Regulations on the Technical Supervision and Management of Boiler Energy Efficiency\" (TSG G0002-2010), which are now approved for issuance and implementation. Content: Attachment: Amendment No. 1 to the “Regulations on the Supervision and Management of Energy-Saving Technologies for Boilers” (TSGG0002-2010) (amendments to the 1st edition issued in August 2010). Attachment A has been modified as follows: Attachment A – Thermal efficiency indicators for industrial boilers. A1: Thermal efficiency indicators for coal-fired industrial boiler products under rated operating conditions. A1.1: For layer-combustion boiler products, the target values and limit values for thermal efficiency under rated operating conditions are shown in Table A-1. Table A-1 Target and Limit Values for Thermal Efficiency of Layered Combustion Boilers under Rated Operating Conditions
Fuel Type | Fuel, on a received basis | Lower heating value, Qnet.v.ar (kJ/kg) | Boiler’s rated evaporation rate (D, t/h) or rated thermal power (Q, MW) | D ≤ 20 or Q ≤ 14 | D > 20 or Q > 14 | Boiler thermal efficiency (%) | Target value | Limit value | Target value | Limit value
Bituminous coal Type II | 17,700 | 0 ≤ Qnet.v.ar ≤ 21,000 | 85,808 | 68,1 | Type III: Qnet.v.ar > 21,000 | 87,828 | 98,4 | Lignite: Qnet.v.ar ≥ 11,500 | 85,808 | 87,82
Note A-1: For boilers that use bituminous coal of Type I, sub-bituminous coal, anthracite, etc. as fuel, the thermal efficiency requirements shall be in accordance with those specified for bituminous coal of Type II in Table A-1. Note A-2: Range of dry ash-free basis volatile matter (Vdaf) for various fuel types; for bituminous coal, Vdaf > 20% ； Low-grade coal, 10% < Vdaf ≤ 20% ； Class II anthracite, Vdaf＜6.5% ； Class III anthracite, 6.5%≤Vdaf≤10% ； Lignite, Vdaf＞37% (the same below). A1.2 For fluidized bed combustion boiler products, the target and limit values for thermal efficiency under rated operating conditions are shown in Table A-2. Table A-2 Target and Limit Values for Thermal Efficiency of Fluidized-Bed Combustion Boilers under Rated Operating Conditions Fuel Type Lower Heating Value of Fuel on a Received Basis, Qnet.v.ar (kJ/kg) Boiler Thermal Efficiency (%), Target Value, Limit Value Bituminous Coal I: 14,400 ≤ Qnet.v.ar < 17,700 → 8782; II: 17,700 ≤ Qnet.v.ar ≤ 21,000 → 9186; III: Qnet.v.ar > 21,000 → 9288. Lignite: Qnet.v.ar ≥ 11,500 → 9186. Note A-3: For boilers that use lean coal, anthracite, and similar fuels, the thermal efficiency criteria shall be in accordance with those specified for lignite in Table A-2. Note A-4: For boilers that use low-quality coal (whose main component is coal gangue, with a lower heating value on a fuel basis of Qnet.v.ar40%) as fuel, the required thermal efficiency value must correspond to the designed thermal efficiency of the boiler; the target value shall be in line with the thermal efficiency target for AI bituminous coal as specified in Table A-2. A1.3 The target and limit values for the thermal efficiency of room-burned (coal powder) boiler products under rated operating conditions are shown in Table A-3. Table A-3 Target and Limit Values for Thermal Efficiency of Room-Burned (Pulverized Coal) Boilers under Rated Operating Conditions Fuel Type Lower Heating Value of Fuel on a Received Basis, Qnet.v.ar (kJ/kg) Boiler Thermal Efficiency (%), Target Value, Limit Value Coal: 9288, based on the actual test results of the fuel. Note A-5: For boilers that use coal slurry as fuel, the limit value for thermal efficiency should correspond to the designed thermal efficiency of the boiler, while the target value shall be in accordance with those specified in Table A-3. The thermal efficiency indicators for industrial boilers fueled by liquid fuels or natural gas under their rated operating conditions, as well as the target and limit values for such thermal efficiency, are shown in Table A-4. Table A-4 Target and Limit Values for Thermal Efficiency under Normal Operating Conditions of Boilers Using Liquid Fuel and Natural Gas as Fuel Sources. Fuel Type, Fuel’s Lower Heating Value on a Received Basis (Qnet.v.ar, kJ/kg), Boiler Thermal Efficiency (%): Target Value, Limit Value. Liquid fuels: Light oil – based on the actual test values of the fuel, 9690; Heavy oil. Natural gas: 9892. Note A-6: For boilers that use liquid fuels other than light oil and heavy oil as fuel, the limit value for boiler thermal efficiency should be equal to the designed thermal efficiency of the boiler, while the target value shall be in accordance with the target values for liquid fuel thermal efficiency listed in Table A-4. Note A-7: For boilers fueled by gas fuels other than natural gas, the specified value for thermal efficiency shall be the designed thermal efficiency of the boiler, while the target value shall be in accordance with the natural gas thermal efficiency target values listed in Table A-4. The thermal efficiency indicators for A3 biomass-fired boiler products under rated operating conditions, as well as the target and limit values for thermal efficiency in these conditions, are shown in Table A-5.
