Greenhouse Heating. 



Subscribers are invited to write the 

 editor of the Heating Department, de- 

 scribing their troubles or asking any 

 questions regarding the heating of green- 

 houses, the piping or boiler-room. But 

 please do not ask us to make a choice of 

 apparatus for you. Each boiler adver- 

 tised in The Eeview is a good boiler, and 

 the advertisers sell them on their merits. 



FIBING WITH HAKD COAL. 



Quite a number of florists in the 

 western part of Pennsylvania, Ohio and, 

 in fact, in all the states where soft coal 

 is used and yet near enough to obtain 

 hard coal, are making the change. Most 

 of them that make this change are hav- 

 ing difficulties because they do not un- 

 •ierstand firing with hard coal, for it is 

 vastly different from firing with soft 

 coal. 



, Probably the same grate could . be 

 used if it was fine enough mesh to suit 

 the size of coal to be used, as the mesh 

 of the grate depends entirely on the 

 size of coal. If No. 1 buckwheat is used 

 a small mesh is necessary, while if egg 

 or grate coal is used a large mesh would 

 give better results. Some florists use 

 the patent grates; something on the 

 principle of the Dockash, of which a 

 number are in the market. 



The common, double, straight-barred 

 grate is probably more generally used 

 than any other and is all right if you 

 know how to handle it, but to fire with 

 smaller size coal it is necessary to know 

 how to handle the fire; here lies the 

 whole secret. Below I will give the di- 

 rections how to fire with No. 1 buck- 

 wheat, which would apply to all the 

 smaller sizes, pea and probably chestnut, 

 and I do not know why it should not be 

 applied to the larger sizes. However, 

 we have never used the larger sizes in 

 the vicinity of Scranton for greenhouse 

 heating, as we have so much of the 

 smaller sizes here, and heretofore they 

 have been so cheap compared with the 

 large sizes, that we have always used 

 the small. If anyone will follow out 

 the following principles in firing he will 

 make no mistake, if the gratebar sur- 

 face is large enough to give the results. 



To a thirty horse-power boiler the 

 grate surface should be 3%x5^ feet, a 

 bricked-in return tubular boiler. I will 

 start my instructions with a new fire, 

 which you would, of course, start with 

 wood, putting on coal a little at a time 

 until you get a bright fire from the coal. 

 It ought not to be more than two inches 

 thick at this time. When it burns up 

 brightly do not put on any more coal

until you see little white spots here and 

 there, at which time do not put on 

 more than four or five scoops until the 

 fire gets to be from eight to ten inches 

 thick, according to the weather condi- 

 tions. 



Never touch this fire with the poker 

 until you clean down after it gets this 

 thickness. If you do touch it, thinking 

 you are going to improve it, you will 

 spoil your fire, as the fine ashes will fall 

 into the crevices kept open by your 

 draft; consequently your draft will be 

 choked and your fire of no account. 



The way to break this fire down is as 

 follows: Before you are ready to clean 

 up put on seven shovels of coal instead
