The Florists' Review 



OCTOBES 15, 1914. 



For use with hot Water there should 

 be an expansion tank, connected to 

 the highest part of the flow pipes, 

 which should be near th» boiler. The 

 connecting pipe should have a shut-oflE 

 valve, so that the gystem can be closed 

 when steam is used. There should also 

 be a water gauge, a pressure gauge 

 and a safety valve on the boiler for 

 use with steam, and air valves at the 

 lower end of the returns. The steam 

 should work satisfactorily if the re- 

 turns can bo three feet above the top 

 of the boiler. 



The combination system, while cor- 

 rect in theory, does not always give 

 good results, and i^o biother of draw- 

 ing off the water and opening or clos- 

 ing the valves, when changing from 

 hot water to steam, 3s a great disad- 

 vantage in the use of such a system. 

 I also doubt whether the efficiency and 

 capacity of the boiler can be increased 

 by making such a change. The steam 

 or hot water is the medium by which 

 the heat generated in the boiler is 

 carried to the places where it is needed, 

 but, although steam readily transmits 

 the heat, it cannot be said to increase 

 the efficiency and heating power of the 

 boiler. For this reason I doubt whether 

 a change in the method of heating the 

 buildings from hot water to steam will 

 have the desired effect in the long run. 



CONDENSATION NOT RETUBNED. 



Our boiler is unnecessarily large for 

 the present size of the houses. A 

 steam trap is connected with it. In 

 the fall and spring, when it does not 

 pay to have a steady fireman at night, 

 we like to run up a few pounds of 

 steam and bank the fire over. How- 

 ever, when the steam runs below seven 

 to nine pounds, the steam trap does 

 not pump the water back into the 

 boiler, but sometimes even forms a 

 vacuum and draws the water out of 

 the boiler, so that there is danger of 

 the top flues not being sufficiently 

 covered with water. Is there any valve 

 that could be used to compel the steam 

 trap to pump the right way, without 

 drawing water back out of the boiler, 

 in case the fire is not looked after 

 quite as often as it is nowt J. F. D. 



The use of a check valve on the 

 return pipe near the boiler would keep 

 the water from being drawn out into 

 the coils, but would not aid the trap 

 in returning the water to the boiler. 

 A small electric ptmp on the return 

 would correct the difficulty. 



Wouldn't You? 



IF you could keep the water of condensation out of your steam apparatus 

 and supply your boiler with chemically pure feed water— if you could 

 maintain a steady, even temperature in your greenhouses and feed ttie con- 

 densation to your boilers, placed above ground -wouldn't you be efTecting 

 a wonderful saving in time, fuel and labor? With the 



Mi%ehead 



i 



that SAVINQ can be accomplished and. furthermore, you'll 

 find the "way out" of all your condensation difficulties. No 

 more trouble, bother, or expense- just simple, automatic oper- 

 ation without any further attention on your part.
