Abstract
285,544. Eley, C. V. A. Nov. 15, 1926. Smoke and fumes, washing.-Apparatus for treating boiler furnace gases comprises a filter chamber 13 connected by a pipe 16 to a liquid tank 17. The gases pass upwards through the filter and enter the tank below the liquid level and escape through an outlet pipe near the upper part of the tank; the gases are drawn through both filter and tank by suction. The filter 13 may contain trays of lime, soda, &c. for absorbing carbon dioxide &c. and a.lso trays of material for collecting heavier flue dust. A spray 15 of waber or water charged with lime, soda &c. may be employed. The liquid tank 17 has a baffle 18 beneath the liquid level, and pipes 19 opening into an outer water-heating chamber 20 having a steam outlet 22. Discharge of gases through a pump or fan 23 is controlled by a valve 25. A helical conveyer 28 is provided in a sump 27 for discharging sediment through an out-take 30 into a chamber 32 from which water is drawn off through a pipe 34. Valves 31, 35 controlling the inlet and outlet of the ash collection chamber may be interconnected and operated at intervals as by the driving means of the helical conveyer.
