范围:1.1 This test method covers the determination of reference ignition temperature of granular activated carbon in flowing air. This test method provides a basis for comparing the ignition characteristics of different carbons, or the change in ignition characteristics of the same carbon after a period of service. 1.2 The ignition temperature as determined by this test method cannot be interpreted as the probable ignition temperature of the same carbon under the operating conditions of a specific application unless those conditions are essentially the same as those in this test method. If it is desired to determine the ignition temperature of the carbon under a specific set of operating conditions, the test may be modified to simulate such conditions, taking into consideration the following variables: (1) air flow rate; (2) moisture content of the carbon; (3) bed depth; ( 4) relative humidity of the air stream; (5) heating rate; (6) contaminants (for example, hydrocarbons, etc.) in the air |
