SPECIFICATION forming part Of Letters Patent N0. 734,328, dated July 21 1903.
' Application filed August 9, 1902. Serial No. 119,025r (Ne model.)
To all whom it may concern:
Be it known that I, GEORGE ROBERT HIN- GELBERG, engineer, a subject of the King of Great Britain and Ireland, residing at 146 Burngreave road, Sheffield, in the county of York, England, have invented certain new and useful Improvements in Steam-Genera- I -tors of the Marine Type, of which the following is a specification.
This invention relates to the setting of multitubular marine boilers provided with means for causing a draft of preheated air to be supplied to the furnaces by the inducing action of a fan or fans, which draws or draw the products of combustion from the furnaces and discharge the said products up a chimney or into the atmosphere. In steam-generators of this type 1, according to this invention,
construct flues underneath the boiler and extending the whole length or nearlythe whole length thereof and arranged in such a way that the greatest possible length of flue is in contact with the bottom of the boiler. The products of combustion from the furnaces after passing through the heater by which air for the furnaces is preheated are led through 1 ducts into one end of the said flues, the fan or fans drawing or forcing the said products through the said flues after they have passed through the air-heater, the main portion of their remaining heat being during their passage through these flues imparted to the boiler, this improving the evaporative efiect and tending to keep the boiler-shell at an equable temperature during work.
I will describe, with reference to the accompanying drawings, an arrangement according to this invention wherein the products of combustion from the furnaces after leaving the air-heater are caused to enter the suction side of the fan or fans and are discharged by the said fan or fans into the aforesaid flues, although it is to be understood that the fan or fans may be between the said lines and the chimney or outlet to the atmos phere, so asto draw the said'prod ucts through the said flues.
Figure 1 is a side elevation; Fig. 2, a plan, and Fig. 3 an end View with parts removed from one-half.
uptake through which the products of combustion from the furnaces pass back through tubes a and thence into the casing f and through the tubes of the heater B, into which air to supply the furnaces enters by the openings b and passes between the tubes of the heater B and into the casing 19 and thence into the furnace.
O is a fan driven by the engine 0 and arranged between the heater B and the fines D underneath the boiler.
E is the uptake or passage leading into the chimney or into the atmosphere.
Theproducts of combustion are drawn by the fan into the casin g f, up through the tubes of the heater B, and through the passage 9 into the fan, by which they are forced down the dowucast h and through the passage D, provided with a wall d, so as to constitute as they pass through the said fluesD imparting a great part of their heat to the bottom of the boiler and then escaping'through the flue D? and uptake E. These flues do not surround the entire shell, as in prior constructions, but are beneath the greater portion of the shell, exposing substantially the entire lower surface of the boiler-shell to the products of combustion. In the drawings the entire shell is exposed to the fines below the horizontal center line passing through the fire-chambers, thus heating the shell at this coldest portion and securing the equable heating of the boiler, producing equal expansion throughout and increasing the life of the boiler. Openings and doors may be provided,
as at C1 in any suitable positions for cleaning the tines D.
Instead of the fan being placedas shown it may beplaced at'the other side of the flues D, so as to draw the products of combustion therethrough instead of forcing them thereinto.
E is a by-pass flue closed by a valve or damper at e when the fan is in action, the said valve or damper being capable of closing the passage g to the fan and opening the inlet to too the by-pass E when the boiler is to be worked by natural draft.
1 claim as my invention 1. A marine boiler having a furnace provided with an uptake and return fire-tubes with a heater-casing having passages for air leading to the furnace and other passages for products of combustion leading from the firetubes, flues underneath the boiler exposed to substantially the lower surface of the boilershell and adapted to discharge the products of combustion into the uptake, an exterior flue or passage connecting the heater-casing with the said flues, and a fan interposed in said passage or flue adapted to cause the products of combustion to flow from the heater through the fines under the boiler to said uptake, substantially as described.
2. A marine boiler having a furnace provided with an uptake and return fire-tubes with a heater-casing having passages for air leading to the furnace and other passages for products of combustion leading from the firetubes, flues underneath the boiler exposed to substantially the lower surface of the boiler shell and communicating with the uptake, an exterior passage or flue connecting said lower flues with the heater-casing, a fan interposed in said exterior passage or flue for drawing the products of combustion through the heatercasing and forcing them through the flues under the boiler, and a branch passage or flue connecting said exterior passage with the uptake and provided with a valve or damper adapted to direct products of combustion directly to the uptake or through the fines underneath the boiler to the uptake, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
