same time increasing somewhat the width orlength of the hopper.
By my present invention I have provided apparatus by `which substantially all head room between the hopper and sluiceway has been` eliminated and bywhich hop ersv of greatly increased width and practica y any length can be used. The practical result of the invention is that hoppers can be constructed with the same capacity as, but much less height than hoppers heretofore used. rlhis results in further savings in boiler house construction costs and correspondingly measures the value of this invention.
ln the drawings accompanying and forming apart of this specification Fig. 1 is a longitudinal vertical sectional view of one form of apparatus embodying my invention; and
Fig.2 is a top plan view partly in sectionV showing my invention embodied in aydiderent type of ash hopper; and
Fig. 3 is a transverse sectional view taken i on line 3-3 of Fig. 1; and f Fig. d is a longitudinal sectional view taken substantially on line ir-11- o Fig. 2. ln Figs. 1 and 3 the hopper is formed by lateral walls'l which extend upwardly from the basement floor 2 of a boiler house, and bottom walls 3 which'are inclined from the middle of the hopper toward either end. The lower ends oi walls ,3 project through lateral walls 1 where openings 4: a're provided and terminate just above screens or grids 5 loto insure ready flow of water and ash over it to the sluiceway 6.
A pivoted door 7 counterweighted as at 8 serves to close and seal each opening 4 and to retain ash and gas under pressure in the hopper. A housing 9 is built around each grid 5 and door 7 as shown to permit ash` to pass through the doorway and into sluiceway 6 without escape of dust into the basement or entry of air into the hopper from the basement. Each housing 9 has a door 10 for inspection and ,clean out purposes.
lnside each housing 9, a high pressure pipe line 11 is provided. rlihis line has a nozzle 12 disposed to discharge water under pressure against ash on wally 3 substantially parallel to the top surface of and close to the wall 3.
/By means of a ball and socket joint in the line 11 the linecan'be moved back Yand forth so as to discharge water from nozzle 12 across the full width oi? wall 3 and opening d.
Ash washed through grids 5 is received on a fluid conveyer formed by water discharged through nozzles 13 in a-sluiceway 6 and is thereby carried away.
Either nozzle 12 may be actuated independ-i ently of the other or both may be actuated together. When both are operated at once care should be taken, with an arrangement as'shown in Fig. 1, that the sluiceway capacity be not exceeded due to the rapid discharge of ash thereinto.L
,At the apex oi the bottom walls 3 a T removed from a wall 3 thewater might overshoot the apex and so wet the ash onlthe other l'side as to interfere with the relagularj discharge of the ash on that side. Also itis an advantage to return the water tothe Wall 3 so it will wash more ash into the sluiceway.
1n Figs. 2 and d l have shown how my invention maybe utilized with a hopper of considerablev width as' well as length but without any head room between the hopper vcated in the top olfa sluiceway 6. The grid? and Hoor being required and without any is substantially flush with the'top of the basement oor`2. Enough slope is given walls 3 loss in speed of ash removal from the hopper.
In these figures the hopper 15 is substantially like the hopper of Fig. 1` but has a width` corresponding to the length of the hopper oi Fig. 1 and a length several times the length of the latter hopper. j lplurality of openings 4 and doors 7 on each A side of the hopper and sluiceways 16 extend along each side of the hopper.v These sluiceways 16 are similar to sluiceway 6 of Fig. 1 Abut run at right angles-to the direction of sluiceway 6 in Fi 1.
By the arrangement o? parts of Figs. 2 and' 4 ash or solids can be removed from the lhopper simultaneously on both sides without danger of clogging either sluiceway.` Ample hopper capacity is thus provided .fwith less ifrertical height than has been possible heretoore. i
An imp tant advantage incidentI to this invention is that a considerable positive gas pressure may be maintained in the hoppers when the doors 7 are closed. This is desirable when such pressure is required to force air up through grinders above'or in the 'upper' part of the hopper to complete the combustion of partl urned fuel thereon and thus sto'increase t e furnace or stoker eiliciency.
The hopper and its doors 7 eilectually -prevent escape `of gas under pressure in the hopper independently of any gas or air pressure in the sluiceway or outside of the doors, the weight of the doors resting against the hopper wall about the openings 4 and the counterweights 8 eiectually.A sealing opening- 4 against gas escape therethrough.
