PLIBRICO Increases Boiler Efficiency 



Showing ease with which PUbrlco 

 B Is laid in place. 



PLIBRICO is a plastic refractory that makes a solid 

 one-piece furnace lining without joints. Plibrico also 

 is unexcelled for baffle construction and repairs. 



It will increase the efficiency of your boiler 15 per cent. 

 It will make your furnace^ gas and air tight and greatly 

 reduce the cost of upkeep. Can be used wherever fire 

 brick is used. Will outwear any fire brick made. 



Shipped in steel containers only. Warehouse stock carried 

 in principal cities for immediate delivery.

ber of feet to where the first supply 

 is below the level of the greenhouse 

 floor, the returns, especially those on 

 the walls, should be carried as high as 

 possible. 



USING TWO BOILEBS. 



I have two houses, one 22x120 feet 

 and one 22x110 feet, running north and 

 south. There is no gable on the north 

 end, where the boiler house is. On the 

 south end the glass is six feet from the 

 ground. The east side has two feet and 

 the west side three feet of glass above 

 lour feet from the floor. The ridge 

 is thirteen feet high. I use a hot water 

 system and have two boilers, one with 

 a grate 24x36 inches and one with a 

 grate 24x48 inches. They are connected 

 and stand on the floor. The houses 

 drop three or four feet from the south 

 to the north end. The pipes run uphill 

 to the south end and the returns from 

 the south to the north end, as the north 

 end is the lower. I should like to keep 

 a heat of 55 degrees in zero weather, 

 but so far I have not been successful. 



How large should the smokestack be? 



A 2%-inch main runs across both 

 houses and from this I have six 2-inch 

 flow pipes and ten 2-inch returns and 

 also two 1^4 -inch flows and four 1^4 -inch 

 returns. The flows are two feet above 

 the boiler, going up, and the returns 

 are level with the boiler inlets. As the 

 boilers have a 4-inch outlet and inlet, 

 I used 2-inch pipe direct to and from 

 the boilers. 



My main return, 2i^-inch, also runs 

 across the houses, but is reduced to 

 2-inch at the boilers. All the pipes are 

 hanging on the three rows of posts, be- 

 cause I have all solid beds. I have two 

 return mains, one 2-inch and one 2^- 

 inch. The returning water is too slow. 



H. B.— Mo. 



Although it is not stated, I infer 

 that the houses are connected and that 

 one house has two feet of glass in its 

 east wall and the other has three feet 

 in its west wall. 



It is doubtful about the number of 

 return mains. In one place the inquiry 

 speaks of a 2 ^^ -inch return and in an- 

 other it states that there are two re- 

 turn mains, one of which is 2-inch. If 

 there is but one 2%-inch flow pipe for 

 the two houses, this accounts in part 

 for the difliculty; even one 2^-inch 

 flow pipe for each house would not be 

 sufilcient. I should use at least 3-inch 

 flows and should run one to each house. 

 It would even be better to use 3%-ineh 

 '.r 4 inch flows, especially if it is a num-
