Show Page 8. The normal procedure for operating the pilot plant (Figure 6) is to start the fluidizing air blower first and adjust the flow. Bed material, sand, is added until approximately 15 ins differential pressure is reached. The propane startup burner is lit and the active bed is heated up to 1500 deg F. The feed hopper is filled with test material and the feed system started slowly, gradually turning down the burner until the bed temperature _stabilizes . at 1200 deg F to 1600 deg F with propane off. For gasification tests, the flue gases are then piped to a special low BTU gas burner where secondary combustion air is added. A continuous pilot provides ignition, and the burner is allowed to fire into a small furnace open to atmosphere at the end.
