Great Grates* 



As fast as old grate bars are burned 

 out many growers are putting in the 

 Martin rocking grate. The call for this 

 grate is largely increased by the fact 

 that the growers who have used it for 

 one or more seasons are almost without 

 exception equipping other boilers with "it. 

 The grate costs considerably more than 

 the stationary bars, but is figured to 

 make a decided saving in fuel, and that 

 is what all the growers are after.

 give me regarding this matter will be 

 greatly appreciated. W. L. F. 



If your piping is sufficient to with- 

 stand the seventy pounds pressure, all 

 you have to do is to provide air cocks 

 at the highest points, plug all safety 

 valves and other openings and connect 

 the city pressure to the main return near 

 the boiler. If the system will not stand 

 the seventy pounds, and you cannot se- 

 cure the desired pressure from an ele- 

 vated expansion tank connected at the 

 same point, place a reducing valve in 

 the service pipe and use such pressure 

 as is necessary to secure the desired re- 

 sults. L. C. C. 



CONNECTING EXPANSION TANK 



I intend to use hot water for heating 

 our greenhouse. The expansion tank 

 will be twelve feet above the boiler. 

 Where shall I make the connection, with 

 the pipe that feeds the coils or with 

 the return pipe? L. F. B. 



It will be better to make the connec- 

 tion for the expansion tank on the main 

 return near the boiler, unless you in- 

 tend to use the pressure for an elevated 

 supply tank, both for supply and ex- 

 pansion, or to utilize city pressure in 

 this fashion, which can be satisfactorily 

 done if the pressure is not more than 

 fifty or sixty pounds. L. C. C. 



MAKING RETURNS LOWER. 



Will I gain anything by changing my 

 returns so that they enter the boiler at 

 the bottom? They now enter the top, 

 seven feet below the greenhouse floor. 

 A drop of fourteen feet would result if 

 they entered the bottom. E. G. 



No advantage could be gained by drop- 

 ping the returns below the sjiell of the 

 boiler. If all returns save the single 

 one carrying the water to the opening 

 on the under side of the boiler can be 

 kept above the water level in the boiler, 

 if a steam boiler, greater efficiency will 

 be secured. I». C. C.
