The specific requirements are as follows. a) Provided that the fuel used meets the design or order contract requirements, the boiler's evaporation capacity or thermal power shall meet the design requirements. The thermal efficiency of the boiler under rated conditions shall not be lower than that required in GB/T 44906. b) The initial emission concentration limit of nitrogen oxides for the boiler under rated conditions shall comply with the relevant requirements of GB/T 44906. The flue gas blackness shall not exceed Ringelmann level 1. c) Under normal operating conditions, the annual available hours of the boiler shall not be less than 7,200h. The number of forced shutdowns for maintenance due to faults caused by poor manufacturing quality of the boiler and its auxiliary equipment and accessories shall not exceed 4 within a 2-year service period or two heating periods.
