I also know exactly what your talking about with the Harbor Freight thing. I'm down the swap stories anytime, ill tell you about the time that a river over flowed into the sewer. A how we had 4 12" Godwins and 3 6" to 8" Godwins pumping down the river. </div></div>
Fluid beds have their own kinds of headaches. All depends on whether it is push/pull system or simply push system. We went to simple push system after the rebuild and I like it much better than when we had ID fans. Now it is just FA blowers pushing ~5000 SCFM into windbox and up through the bed. You adjust your airflow to match the burn and allow proper amount of O2 in the freeboard. Using airflow, lance gas, and proper feed, I can set her up to cruise all night without touching the controls as long as sludge feed remains constant. On occasion we have had exceptional high BTU sludge and if the cake off the press is good we can go autogenous but that is pretty rare, maybe a couple weeks out of the year. One great thing about fluid beds....no clinkers around the gas lances from reburned ash. We don't use oil for heat up anymore because of strict air quality regs, even though we have a scrubber.
