Show It was hypothesized that the total dissolved solids (TOS) in the process water had a significant effect on the stack particulates. Therefore, a particulate test was conducted with no feed to the system, high TOS in process water and approximately the same flue gas flow rate as in the other tests. The test showed a particulate emission of 0.02 gr/dscf with the process water TOS of approximately 50,000 parts per million (ppm) confirming the hypotheses. The particulate tests with vermiculite and the two mixes of brominated sludge, soil and salt cake were also successful. These results are summarized in Table 4. System Stability Tests A number of system stability tests were conducted with various feeds in preparation for the planned trial burn tests. The following tests were performed: Liquid waste feed tests: MMBtu/hr (MM=I,OOO,OOO) at between 0 and 2.2 MMBtu/hr. Liquid waste was fed up to 2.7 a steady rate and was cycled Water spray cycling: Water spray was cycled at rates between 0 and 2.5 gpm. Methanol/water feed: A mixture of 80% methanol and 20% water (7,000 Btu/lb) was fed up to 2.1 MMBtu/hr. Methanol/CC1 4 feed: A mixture of 77% methanol and 23% CC1 4 (7,500 Btu/lb) was fed up to 3 MMBtu/hr. Oiesel/CC1 4 feed: A mixture of 62% CC1 4 and 38% diesel (7,500 Btu/lb) was fed up to 3 MMBtu/hr. High Btu soil feed: 4,000 lb/hr. of soil/diesel mixture with heating value of 330 Btu/lb was fed simultaneously with liquid fuel at 2.2 MMBtu/hr. Total heat input from waste was 3.5 MMBtu/hr. Satisfactory system response and flame stability were demonstrated in all the above tests. RCRA/TSCA Trial Burn A combined RCRA/TSCA trial burn was conducted in which PCB and HCE were fed with 4,000 lb/hr of soil and liquid PCB and CC1 4 in 315 lb/hr of liquid feed. Four tests were completed. Only solids were fed in the first test. A trial burn report detailing the results of these trial burns will be issued. |
