after April 1 the temperature is seldom 

 below 35 degrees. Will the foregoing 

 plan give the proper temperature for 

 the crops mentioned? 



If I should connect the piping with 

 the greenhouse boiler, will a cut-off 

 valve be required at the head of each 

 frame or only on the flow and return 

 in the boiler roomf Can you give the 

 heating capacity of the boiler? It is 

 a round boiler, four feet high above the 

 ash-pit and twenty-two inches in diam- 

 eter. The fire-pot is twenty-seven 

 inches high and eighteen inches in 

 diameter. There is a 2-inch water leg 

 around the fire-pot. The boiler has 

 two 2-inch flows and two 2-ineh returns.

The plan proposed for heating cold- 

 frames by means of hot water pipes is 

 a good one and there should be no diffi- 

 culty in keeping up the desired tem- 

 perature in the frames. It will be 

 necessary, of course, to have the boiler 

 two or three feet below the level of the 

 return pipes. A heater of the size de- 

 scribed should be large enough to sup- 

 ply 275 to 300 square feet of radiation. 

 It will be best to have a valve upon 

 each pipe where it enters the hotbeds. 



HEAT FOR TOMATO BEDS. 



I intend to grow plants for a catsup 

 factory here and I shall build thirteen 

 beds, 5%xl33 feet. I shall heat with 

 steam, using a tubular boiler. As I am 

 not familiar with steam heating, I 

 should like to get some advice on the 

 matter. I have plenty of 2-inch pipe on 

 hand. My idea is to run a 2-inch pipe 

 through the center of each bed, putting 

 a stop-cock at the farther end and not 

 returning the steam to the boiler, but 

 letting it blow out of each valve. Now, 

 a little advice on connecting the boiler 

 would be greatly appreciated. The 

 ground is almost level. I have to get 

 my water pressure from a storage tank 

 ten feet above ground and 150 feet 

 from the boiler. Would this give pres- 

 sure enough? 



I should also like to get a little in- 

 formation on chemical fertilizers for 

 tomato plants, as the ground is not as 

 rich as it ought to be. The seed will be 

 sown in rows six inches apart and the 

 beds will be ground beds, covered with 

 plant bed cloth in severe weather. 



W. S. 



The plan proposed for heating the 

 hotbeds should work all right, as it will 

 not only heat the air above the plants 

 but will also furnish bottom heat. The 

 pipes should be given a slight fall, so 

 that the water will not become pock- 

 eted. While a greater height for the 



THE CLARK OIL BURNER 



TRIED ADTD TESTED FOR THREE YEARS OK STEAM AND HOT WATER. 



Mr. 



Burton B. Crane, Florist, 27 South 16th St., Kansas City, Kan., states: 



I haTe used tbe Clark Oil Burner in my steam boiler the last two winters and think it far 

 better than anything I know of for greenhouse heating, as it requires but little attention, and is 

 very economical In tbe use of oil. I have run my boiler continuously for forty-eight hours without 

 attention. I use the heavy fuel oil, which costs me two cents per gallon delivered, and find it fifty 

 per cent cheaper than screened soft coal at ^3.30 per ton. Am not counting cost of handling coal 

 and ashes. 



Mr. L. C. Fields, Florist, 328 N. 10th, Kansas City, Kan., states: 



I have used the Clark Oil Burner in my hot water boiler for the last two winters, and think it the 

 best proposition for greenhouse heating I have ever used. If you could only fix it so it would start 

 itself it would be O. K., as it needs no attention after it Is started. 



Facts Regarding the TTse of Oil as a Fuel. Perfect combustion is the object and can be obtained 

 by thoroughly atomizing and spraying the Oil into tbe flre box. This is done by the action of steam 

 upon the Oil while passing through an especially constructed atomizer, or oil burner. There are a 

 great many so called Oil Burners being placed on the market, but the majority of them go to the 

 Junk pile. 



Tnft Clark Suction Feed Oil Burner is adapted for low and high pressure steam boilers, hot water 

 boilers. Furnaces, Ovens, etc. Our system does not require a lot of expensive pumping machinery 

 for forcing the Oil through the Burner to tbe Fire Box, but by the action of the steam passing 

 through the Burner. The Oil is sucked up from below the burner, passing through the burner it is 

 thoroughly atomized and blown into tbe fire box, this suction feed insures safety, as when steam is 

 shut off the burner, the oil stops flowing through the burner, while with the pressure or gravity 

 feed burners. If anything should go wrong while tbe fireman Is out, the fire box and probably the 

 boiler room would be flooded with oil. this oil coming in contact with tbe hot fire box would generate 

 gas, and in all probability an explosion would follow. 



Our system automatically maintains an even pressure in the boiler. The flow of oil is not governed 

 by means of a valve in the supply pipe, but by varying tbe steam pressure on the burner, that is by 

 reducing the pressure on the burner, the flow of oil is reduced, and by increasing the steam pressure 

 on the burner, the flow of oil is increased. Tbe variation of steam pressure on tbe burner is caused 

 by an especially constructed pressure regrulatiac valve, which is placed in the steam pipe running 

 from the boiler to the burner. 



This pressure regulating valve is quickly adjusted to any pressure required in the boiler. After 

 it is set, it automatically varies the pressure on the burner, which reduces or increases the flow of 

 oil as required to maintain an even pressure In the boiler. In other words, if the pressure rises higher 

 than that at which tbe valve Is set, the oil is reduced, if tbe pressure drops below that at which the 

 valve is set the oil is increased. 



Our burner has run forty-eight hours in succession without attention or variation of one pound 

 of steam, bear this in mind when investigating oil burners. 



Our Oil Feed Tank is designed especially for our system. In this tank is a float, which maintains 

 a constant level of oil In the tank, the tank is set so the oil level should be two Inches below level 

 of burner nozzle. 



We have endeavored to explain the theory upon which our system operates, and believe that, after 

 reading the accompanying directions, any steamfltter can properly install; and can be successfully 

 operated by anyone who is capable of firing a boiler. 



Further information will be cheerfully given upon request. 



Tests made with our burners in both steam and hot water boilers show that 85 gallons of heavy 

 fuel oil equal one ton of screened soft coal. Write us for estimate on your plant.
