The Weekly Florists' Review.

with a capacity of 6,000 gallons. Would 

 it be necessary to place a check valve 

 on this pipe? "Will a smokestack twelve 

 inches in diameter and thirty feet high 

 be sufficient? The grate area of the 

 boiler is twelve square feet. We shall 

 use wood for fuel, with possibilities 

 of using coal later. H. K. 



For the houses described, it will be 

 satisfactory if two 2y2-inch flow pipes 

 and nine 1 14 -inch returns are used, 

 though seven or eight 2-inch returns 

 would be better. The plan of connect- 

 ing one of the returns with a stand 

 pipe is a good one, but there should be 

 no check valve in the pipe, unless a 

 closed system is desired, in which case 

 a safety valve will also be required. 



The size of the smoke flue will de- 

 pend upon the quality of coal, but for 

 a poor grade of soft coal a 15-inch 

 chimney would be desirable. 



SLOW CIRCULATION. 



We have two houses, running north 

 and south. Each house is 17x60 feet, 

 ten and one-half feet to the ridge and 

 four feet to the gutter. These houses 

 are boarded at the sides and between 

 the two houses. The west side of the 

 west house contains two feet of glass. 

 The south ends of both houses are glass. 

 The north ends are protected by the pot- 

 ting shed and boiler house. The heat- 

 ing apparatus consists of a No. 4 

 Humber sectional boiler. The pit is 

 only two and one-half feet deep, on 

 account of water. A 4-inch pipe rises 

 five feet above the boiler and then ex- 

 tends the width of both houses. A 

 3-inch flow for each house is then taken 

 from this pipe, dropping to within two 

 feet of the floor under each of the out- 

 side benches, with a drop of about 

 eleven inches in the sixty feet, return- 

 ing to the boiler in a 3-inch pipe. 



When we fire harder than usual, the 

 water boils out of the expansion tank, 

 making it necessary to fill the boiler 

 every day. The expansion tank is six 

 inches above the highest part of the 

 system. We wish to maintain a tem- 

 perature of about 50 degrees. Last win- 

 ter the outside temperature in this 

 part of Utah went down to zero on two 

 occasions. I am desirous of making 

 such changes as will remedy this un- 

 satisfactory condition. Any informa- 

 tion you can give will be greatly appre- 

 ciated. W. H. 



When large pipe is used, and espe- 

 cially when the returns are below the 

 top of the heater, the circulation is 

 slow and the trouble reported may be 

 expected. The radiation is slightly de- 

 ficient for zero weather, but would an- 

 swer at 10 degrees above zero. The 

 circulation would be improved by run- 

 ning the 3-inch flow pipes on the plates 

 and carrying the returns as high as pos- 

 sible, giving each a slight fall. 



BOILER AND PIPING. 



Would you please give me some in- 

 formation in regard to the piping of 

 my greenhouse? It runs east and west 

 and is 21x100 feet. The walls are four 

 feet high and are made of cement. 

 There will be no glass in the side walls. 

 The height to the ridge is ten feet. The 

 east gable is of glass. There is an en- 

 trance at tbe .north side, in the center. 

 The- house- is built with a slope of one 

 foot from the east to the west, and the

In connection with a steam heating plant. Carry 40 or 

 50 pounds pressure on the boiler and set the valve for 5
