TROUBLE WITH TWIN BOILEBS. 



We have two tubuhtr-btrilers; No. 1 

 is twelve feet long and forty-eight 

 inches in diameter; >lo. 2 is fourteen 

 feet long and forty-eight inches in 

 diameter. They connect with a 4-inch 

 overhead feed. There is a globe valve 

 in the ■ stand pipe , of each, so as to 

 run each independently, and there are 

 swing pUa to take* care; of the expan- 

 sion w'hen both are used at the same 

 time. The return main", 2-inch,'' runs 

 in front of No. 1 to No. 2. At the far 

 side of No. 1 a tee is placed; from 

 this the 2-inch pipe is continued hori- 

 zontally for about two feet; in this 

 pipe- a check valve -is placed. Then 

 there is a drop to below the lower tube 

 a^d in this vertical pipe is placed a 

 ^ate valve; then the pipe enters the 

 boiler head near the hand-hole. No. 2 

 is connected in the same way; there 

 is a passageway of about six feet be- 

 tween the boilers. The piping is run on 

 the gravity system. 



Either boiler works satisfactorily 

 when run separately, but when both 

 are under steam No. 1, the smaller, 

 takes all of the return water, so as to 

 make it necessary for a man to be 

 therte continually to close and open the 

 valves. We have about 13,500 square 

 feet of glass. I am enclosing a rough 

 diagram. Either boiler alone has taken 

 care of the place, but we think it more 

 ecohomical in severe weather to run 

 them in battery. A pressure of thirty 

 pounds is the limit. E. E. H. 



It is not possible to get a perfectly 

 clear idea of just how the piping is 

 arranged, either from the sketch or the 

 description, but if the return pipe is 

 carried above the water level in the 

 boiler it would be possible for all of 

 the return water to go to boiler No. 1 

 and still there might be no trouble 

 with the return water when only one 

 boiler is being fired. To correct the 

 difficulty BO that the return will feed 

 both boilers, drop the return so that 

 it will be below the water level. There 

 may be some other complication, not 

 indicated in the inquiry, but this is 

 the only one which seems to account 

 for the difficulty. 



A NORTH CAROLINA HOUSE. 



How many lines of 2-inch pipe,, for 

 hot water, will be required to beat a 

 greenhouse 30x100, with three feet of 

 glass in the sides? The house is to be 

 kept at a temperature of 50 degrees 

 when the outside temperature stands

I have the Kroeschell Boiler six years; 

 It is heating 17,000 sq. ft. kIbbs. No 

 other l)ut a Plat* Boiler for me.

The Kroeschell has taken the place of 

 four cast iron boilers at a big saving in 

 coal. We are using It now for the fifth 

 year. The longer we use it the better 

 we like It.

After using your No. 12 Kroeschell 

 Bolle;* 1 came to the conclusion that had 

 'I to install more boilers it would be the 

 Kroeschell and no other. It really Is a 

 pleasure to heat, no trouble to get the 

 desired beat In a very short time.

The Kroeschell Boiler I Installed last 

 year usually mna from 10 p. m. to 6 a. m. 

 without attention. I do not have the 

 least trouble to keei^ temperatures in the 

 coldest weather. The boiler has given 

 entire satisfaction. 



-The Kroeechell Is the best boiler we 

 have ever handled.

We spent flOO.OOO in building and 

 equipping the largest modern mushroom 

 plant in the world.. We purchased in 

 every instance the best of everything we 

 could get, and the fact, tbat ,we installed 

 a Kroeschell Boilei; to furnish our heat 

 is sufficient evidence 'of our' opinion of 



same. 



Since installing this boiler and operat- 

 ing it we have never had any reason to 

 change our opinion. ' ^
