266 STOtE FOR IIEATtNG AND DRYING. 



with the great fires they employ for their boilers. It has 

 been shown to be useful in the confectioners art, and pro- 

 bably it may be equally so in* baking biscuits for the navy; 

 nor less so in drying linen for the laundress, dyer, calico- 

 printer, and bleacher. I have myself found it well accom- 

 modated for a chemical elaboratory. 



The efficacy of the stove in ventilating, boiling, and 

 steaming may easily be shown. In manufactories and rooms 

 generally the heated and noxious part of the atmosphere 

 ascends towards the ceiling : if then the air-flue M, Fig. 3, 

 is continued upward according to the height of the room in 

 which it is placed, the air will be drawn from the top, and 

 the room become ventilated, while from the opening atN it 

 is supplied, if requisite, with warm air. 



It is unnecessary to show the various ways in which a 

 boiler may be connected with this plan : it is sufficient to 

 observe, that in the space allotted for the fire-place in Fig. I , 

 there is sufficient room within the body of the stove for this 

 purpose; and that if the circulating air be made to pass 

 over the boiler, evaporation may be carried on very expe- 

 ditiously by the air removing the vapour as it arises. Fi- 

 nally, if another division of the flues be made in the man- 

 ner shown Fig, 2, it might form a steam-pipe or flue, run- 

 ning the course of the air and fire-flues, to convey steam to 

 one or more apartments of the stove; or extended beyond 

 the stove for heating the room in which it stands. One of 

 the air-flues might occasionally be adapted to this use. It is 

 obvious that the power of steam in a heated apartment 

 would be not only greater, but better kept up. Iu steaming 

 it would be necessary to close the apartments of the stove, 

 and to give air to the fuel by a different course.

Its form and di- 

 mensions ad- it necessarily of the form described in the drawing, nor are the

is evident that the air-flues themselves may be converted 

 into chambers for drying, &c. ; and the fire-place bf Fig. 3 

 is well adapted to receive an apparatus for the decomposition 

 of coal, &c. ; for producing all the effects of the thermo- 

 lamp, or illuminated smoke, &c. But it is needless to enu- 

 merate
