Ferguson Broh. , Omaha, Neb. , write aa follows : 



It might interest you to know the results obtained with the Kroeschell 

 Greenhouse Boiler and Kroeschell Piping system. 



We have just had a night of 14*^ below with a stiff wind blowing and we 

 carried the house at 62*^ with the boiler at 170'^. The house is piped for 50° 

 and as we are using a cheap grade of slack, the result speaks for itself. 



We were told by the dealer when we ordered the coal that we could not 

 burn it, so we bought a car of good coal to help along if the slack would not 

 give results, but it was not necessary. The Kroeschell Generator cer- 

 tainljr helps the circulation and the new method of piping for hot water is a 

 surprise to some of the greenhouse men in this vicinity.

two and one-half feet of glass in the 

 east wall, and shows three coils con- 

 taining five 1-inch pipes. A temperature 

 of 50 degrees is desired in this house. 

 The piping seems to be properly ar- 

 ranged and adjusted, except that for the 

 short houses, in which 50 degrees is de- 

 sired, four 1-inch pipes in each of the 

 coils would probably answer. Thirteen 

 or fourteen 1-inch pipes should answer 

 in the long house, for 50 degrees. 



There is also a house 8x84, across the 

 north end of the other houses, in which 

 a temperature of 40 degrees is desired. 

 The coil of three 1-inch pipes, together 

 with the 3-inch main which passes 

 through it, should give the heat desired. 



The question does not give the size of 

 the dwelling, but in severe weather the 

 boiler would probably have all that it 

 could handle to heat the five green- 

 houses. When 10 degrees above zero 

 outside, however, it could probably heat 

 the dwelling as well. The use of a single 

 stove in the dwelling, when the mercury 

 drops to zero and below, would proba- 

 bly furnish all of the heat needed. 



ATTACHING A GENERATOR. 



Tn attaching a generator to a hot 

 water system, with the tank up above 

 the boiler, higher than any other part 

 of the plant, does the hot water have to 

 travel all around the system before the 

 generator begins to work? The gen- 

 erator is to be attached to the main re- 

 turn near the boiler, and connected 

 directly with the tank above. Some of 

 the water travels 180 feet and back. 

 L. A. D. 



It is diflScult to make out just what 

 information is desired, from the way 

 the question is written. The best way 

 would be to connect the expansion tank 

 with the highest part of the flow pipe. 

 The circulation begins as soon as the 

 water in the boiler becomes hot, the 

 heavier cold water pressing in from the 

 return and forcing the warmer and 

 lighter water from the boiler up into 

 the flow pipe. The circulation is con- 

 tinued and becomes more rapid as tho 

 temperature of the water increases. 



Whatever method of obtaining a 

 closed system is used, for the purpose of 

 running it under pressure, there is prac 

 tically no effect until the water in the 

 boiler has reached about 212 degrees, 

 which would be the boiling point in an 

 open system. By closing the system it 

 is possible to raise the temperature at 

 which the water will boil, and this not 

 only hastens the circulation, but, as the 

 water in the coils will also be hotter, 

 the eflBeiency of the radiating surface is 

 increased proportionately. Where a 

 generator is used it goes on the pipe 

 leading to the expansion tank.
