In these fluesthe temperature is approximately 450 these main flues the hot gases passto the chimney through Green fuel econo-mizers, made by the Fuel Economizer Com- pany, o f En-gland and theUnited these econo-mizers the tem-perature of thefeed water israised from 80degrees to 250degrees. A by-pass is arrangedfor cutting outthe fuel econo-mizers and pass-ing the gases di-rect to the chim-. nozzle, then a low water and safety valve combined, andstill further back a manhole, on the cover of which is agovernment pop safet}^ valve. The working pressure is125 lbs. per square inch. This type of boiler is a slow ney, to allow for inspection and repairs to the econo-mizers. The steam piping is made of solid welded tube.
