to the temperature specified in Article 5.3 of this Standard before municipal solid waste can be
added. From the beginning of the addition of municipal solid waste, the amount of input shall
be gradually increased until the rated waste treatment capacity is reached. During the startup
phase of the incinerator, the incineration temperature in the furnace shall meet the requirements
of Table 1 of this Standard; and the incinerator shall reach a stable operating condition within
4 h.
7.2 When the incinerator is shut down, the waste combustion support system shall be started
from the beginning of the cessation of the addition of municipal solid waste to ensure that the
remaining waste is completely burned and the requirements for the incineration temperature in
the furnace specified in Table 1 of this Standard are met.
7.3 If a fault occurs in the incinerator during operation, it shall be repaired in time and restored
to normal as soon as possible. If it cannot be repaired, the addition of municipal solid waste
shall be stopped immediately and the furnace shall be shut down in accordance with the
requirements of Article 7.2 of this Standard. The continuous emission time of pollutants for
