BOILEB AND STACK. 



I plan to build two greenhouses 21x 

 150 feet, five feet to the gutter and 

 twelve feet to the ridge, which should 

 be run at about 60 degrees in the cli- 

 mate of northern Indiana. Will you 

 kindly tell me what size of boiler will 

 be necessary, using steam heat, and how 

 high the stack should bef F. A. K. . 



Any boiler rated at 5,000 feet would 

 be all right. It will take about 4,000 

 running feet of l^^inch pipe, but T 

 would get a boiler rated at 5,000 feet. 

 A stack two feet in diameter and forty 

 feet high will serve. F. R. 



GAS, COKE, COAL? 



Please furnish information as to the 

 relative heating value of hard coal, 

 coke and natural gas, when either is to 

 be used in the return tubular type of 

 boilers and under normal conditions. 

 The gas is under a pressure of one and 

 one-half to three ounces. I would in- 

 stall the latest improved burners and 

 mixers, but would use no steam or com- 

 pressed air in connection with the gas. 

 The ruling prices in this vicinity are: 

 Hard coal, $6; coke, $3.50; gas, 35 cents 

 per thousand feet. H. 



The results obtained when the fuel is 

 used under a tubular boiler might be 

 different from the results as they have 

 been determined in a small sectional 

 heater. In the latter case the coke 

 would be the cheapest of the three fuels 

 at the prices mentioned, but this would 

 require that it be so burned as to secure 

 its full effieien^cy. Gas would need to 

 be available' at 20 cents to equal the 

 price of coke, and at 25 cents to be 

 comparable with the price of hard coal. 

 In favor of the gas should be noted 'the 

 saving in the expense of firing and of 

 removing the ashes. Using it under a

Heated by No. 15 Kroesohell Boiler, Kroeschell Scinch Return Piping System and 

 Kroeschell Generator. Greenhouses each 28 feet by 200 feet. Garland Construction. 



The mains are arrangred to take care of a future addition of 40,000 sq. ft. of grlass; 

 2-inch returns are used throughout the entire range and each 2-lnch return line is 

 controlled by 1-Inch gate valve (strictly a Kroeschell feature) .insuring perfect control. 

 It is a gravity Job; the circulation is perfect, reaching the extreme ends of range in 

 fifteen minutes. The Kroeschell Generator (the high speed gear for hot water heat- 

 ing) is also used for this system. 



"Your No. 15 Kroeschell Boiler heats our entire range. We maintain 

 a temperature of 60 degrees in our greenhouses, and this temperature is 

 easily maintained even in the very coldest weather. Your boiler has given 

 entire satisfaction. It is the best and quickest heater I have ever used or 

 seen. I have found the boiler very economical in the use of fuel and labor, 

 as it is not necessary to use the best coal, and any labor will do for a 

 fireman. The Kroeschell Piping System with Generator works like a charm. 

 When ! want to sulphur, I can heat the water up to 230 tq 240 degrees and 

 I get the same results as from steam. Seelitf is believing — all Growers are 

 invited to call. Any further information concerning boiler and piping 

 system will be gladly given. We had a large number of Florists at our 

 place recently, and they all thought we had the finest equipped plant in 

 the business." j^^ RIVERBANK COMPANIES,
