Improvements in Apparatus for Heating* and Ventilating*, more especially intended for use in Creating* Currents for tlie Ventilation of Sewers. I Stephen Holman of 15 Great George Street in the City of Westminster Engineer do hereby declare the nature of this invention to be as follows :— My invention relates to apparatus for heating and ventilating and is more especially intended for use in the ventilation of sewers wherein the foul gases are 5 drawn therefrom by a burner or burners heating a stove or furnace and the principal object of my invention is to prevent any danger of explosion due to the ignition of combustible gases which may be present in the sewers. According to my invention I provide an arrangement wherein the flame or flames of the burner or burners of the stove or furnace is or are provided with passages 10 which are distinct and separate from those through which the air or gases from the sewer pass. A convenient arrangement is to enclose the burner in a chamber from which a tube arises, this tube being surrounded by another tube or series of superposed rings provided with a cover so that the products of combustion from the stove or 15 furnace burner or burners pass up the inner tube and down between it and the surrounding tube or rings and through an outlet provided therefor. The air and gases from the sewer pass up outside the last named tube or series of rings to the exit chamber or column. The passages may have projections or webs extending into them to afford heating surface. These projections or webs may be cast on the 20 aforesaid tubes or either of them but preferably upon the aforesaid surrounding tube or series of rings. The passage or passages for the sewer air or gases around the aforesaid surrounding tube or series of rings may-be limited to any determined area by means of a cylinder or series of superposed rings.
