This mania relates to aleamet of steam and. is especially useful m connect on with stoker fired"boiler furnaces 1n assoc1a tion withsinuous header type boilers and it is in connection 'withfsuch' an'installation that it will be described. I 7 y I proposeto supplement the boiler by boiler tubes arrangedto define a substantial part of thecomb'ustion chamber such tubes therefore m'being v ry larieli subject to radiant heat by virtue .ofwhic e size of the boiler proper may, be iye'ry materially reduced. By such a construction -I am enabled to operate the iz'boiler at greatly increased rates, in comparison to standard practice and design.
One of the .primary objects of my inVen-' tion, therefore, is to provide a boiler and furnace in whichthe rate of eyapo'ration may be increased whereby moresteam maybe generated from .an installation of standard size or other words of generating'agiven amount of, steam 'from a smaller installation than ossible under existing methods.
- org ci-rculation'ftawarious rtions of a sinuso the circulation ofthe boileras awhole.
Another ob'iect is'the provision .of means ation within some of the evapcrating I surfaces is": established by. the parsuch evaporating surfaces;
'bu'stion space arranged-with respect to'the tubes so as to, effect circulation. t
. Still another object. is to so arrange the boiler so that the refractorystructureof the furnace may be greatly simplified and cheap ened and the life thereof greatly extended.-
How thel foregoing,- together with such other objects and advantagesas may hereinafter appear, or are incident to my invention,
are realized, is illustrated.- in preferred. form f sets of tubes '3 and 4; it will be seen that the ooistallation embodying my invention;

By caniinterfering With the circulation of the. bal-' anceoftheboiler.
on the line 3+3 ofFig. 1;1and
Fig. 4 is a fragmentary cross section taken 1. Referring to the rawings the reference character ,A denotes a combustion space in which the fuel is \burned, the reference character B, a Stoker typical of any one of a number of similar stokers to which air is supplied ,under.pressure,'and C, a sinuous header type boiler located above the combustion space A. The combustion space A is defined on its 3 and 4. The sets of tubes 1 and 2 extend substantially horizontally of' the combustion space and at opposite sides thereof each connecting into a pair of upright sinuous headers 5 and Gwhich headers are connected by suit: able means .7 to the end header'sections 8 of The sets of tubes 3 and 4 are each composed ofa double row of upright tubes 9 and 10 andjdefine the two other vertical sides of the 75.. combustion space. Each set of 'tubes 3 and 4 connects its upper header 11 to its lower header 12 which headers are common-to the .two rows oftubes making up each set.' The upper headers 11 are connected by suitablegso means-131m various header sections of the boiler Ci The headers 6 and their connections 7 tom stitute downcomers and the sets of tubes 1 85.. inclination, of the circulatory system. The headers their respective connections are i of a size such asynot 'to'retard the rapid cir- Y culation' produced by the exposure of the sets v bining thisarrangement with a sinuous head- "er type boiler lam enabled to connec the hea ersfi and 6 of the sets of tubes land 2 .into gp' articular sections of the boiler without Referring now to the arrangement of the tubes comprisin each set are arranged in two rows 1 with the tu es of the row 10 toward the outside of the boiler. directly in back of the tubes 9 ofthe inner row, b virtue of which the outer tubes are shaded y the inner row. Stated in another way, the inner tubes 9 will I absorb radiant heat very rapidly while the a outer tubes will be protected or shaded, from such heat. Thus the outer row of tubes will func'tion'as downcomers and theiinner row as upcomers whereby circulation is cre- 3 m ated within said tubes. As before stated these tubes are provided with headers, the upper of i which are connected to various sections of the sinuous header type'boiler O thus connecting them into the circulatin syst'emof the boiler. 5 Hence the advantages herei'nbefore pointed out in 'connectionwith the set of tubes 1 and 2 also becomes apparentjin connection-with the sets oftubes'i3 and4; .3 n When desirable to further" insure rop r circulation additional shading of the outer rows of tubes 10 may bev pro aided by locatingirefractories 14 between theirows of tubes Fig. '3 shows tlie--rear tubes 10enclosed'in tiles .1 5. Thusijt will be, seen that these tubes 11d besides acting asdowncomers by virtue 0 their beingscreened-or' shaded by the tubes 19, also 'c oo1 the tiles/1'5 as. do the tubes 9, so that the-. maintenanoe' frdriiieroSioii or-high temperatures willbe'considerably decreased. Itlis to 'be-noted thaticombustion will not be destroyed by the chilling effect of the rapid absorption of heat by the tubes defining the combustion space, because. of the live bedof 5 coal and the air introduced With-the fuel. Icl'aim:
v Aboiler and furnaceincludingtwo set of substantially horizontal tubes, a air ofhead ersjor each set, two sets of upr ght tubes, a
pair of headers for each set,each uprightset comprising a double row of tube having refractory material therebetween, one row be-- I ing' shaded by the other and by said refractor material and alldefining the "four uprig tl walls of the combustion chamber, a
boiler, located. above said chamber, connections between the first, mentioned headers and the boiler, connections between the upper headers of the second mentioned pair of 5 headers and the boiler, and means for admitting fuel to the combustion chamber. 7 In testimony whereof, I have hereunto signed myname.
