Greenhouse Heating. 



Subscribers are invited to write the 

 Editor of this Department witli regard to 

 any details of greenhouse heating that 

 are not understood. But please do not 

 ask The Review to make a choice of ap- 

 paratus for you. The greenhouse heating 

 equipment advertised in this paper is, we 

 believe, the best for the trade to buy, 

 and each article the best in the special 

 Held of its adaptation. 



CLOGKJED BY CONDENSATION. 



AVo are sending you a description and 

 sketch of our heating system, so that 

 you may bo able to give us some advice. 

 As we have trouble in draining the sys- 

 tem evenly, we propose to abandon the 

 old 4-incli return and install two 2-inch 

 returns, one for the west liouscs and the 

 other for the east houses. There is a 

 fall of two feet or more from the north 

 to the south end, for the return of the 

 condensation. The boilers sire about on 

 the ground level, but are about three 

 feet below the level of most of the 

 lange. There is a trap on the top of the 

 l)oiler, with a receiver at the bottom. 

 According to the manufacturers' figures, 

 the trap should be of ample capacity. 



I think our trouble is largely due to 

 the fact that we run the system on low 

 ])ressure— not enough to work the trap. 

 It takes nearly five pounds of steam to 

 work the trap. We have a great deal of 

 mild w'eather, when only a little steam 

 is required and not enough pressure is 

 kept up to work the trap. During such 

 times the pipes fill with condensation, 

 which prevents uniform distribution of 

 the heat. 



We have two boilers, each fifty-four 

 inches by fourteen feet, and each con- 

 taining thirty-six 4-inch tubes, fourteen 

 feet long. They are called 60-horse- 

 power boilers. They are located direct- 

 ly south of the houses, with which they 

 are connected by a 6-inch main flow, 

 as shown by the dotted line in the 

 sketch. To the boiler is attached, also, 

 a 4-inch main return, with which all 

 the houses except the south two are con- 

 nected. The fuel used is natural gas. 

 The west six houses are used for car- 

 nations and require a temperature of 

 55 degrees at night. The east five 

 houses are for roses and need a night 

 temperature of 60 to 65 degrees. The 

 north three houses should have a tem- 

 perature of 50, 55 and 60 degrees, re- 

 spectively, and are used for potted stock 

 of various sorts and for propagation. 



The side walls consist of three feet 

 of wood or concrete and two feet of 

 glass, except in the south two houses, 

 which have 7-foot walls, with three feet

The Kroeschell Water Tube Steam Bofler 



Our WATER TUBE Steam Boiler has WATER 

 FRONT. WATER SIDES. WATER BACK and is pro- 

 vided with immease SELF- CLEANING HEATING 

 SURFACES and circulating water tubes. 



The WATER TUBE PRINCIPLE is adopted from 

 the large water tube steam boilers used for power 

 work; flue surface used in this manner is much more 

 effective than fire tubes. 



With the water tubes the water circulates 

 THROUGH THE TUBES, while the OUTSIDE OP 

 THE TUBES is exposed to the heated gases. 



The hottest gases impinge against the crown sheet 

 fire surface, then follow a downward course along the 

 smooth inside surfaces, leaving the boiler at the coolest 

 part through the rear of ashpit base. 



In this manner the fire travels along six surfaces, 

 transmitting the heat to the thin water ways, at the 

 two sides, the top. the front and the back of the boiler, 

 and surrounding the water tubes. 



This boiler is the fastest steamer in existence. 



No other boiler can equal it for fuel economy.

WHAT THE USERS SAY 



Walton, N. Y,. Jan. 10, 1916. 



Your new No. 4(5 WATER TUBE STEAM BOILER 

 is the fluest steam boiler we have ever fired, and have 

 fired eleven different makes before. 



Your boiler keeps steam from 9:00 P. M. to 6:00 

 A. M. without attention in zero nights. 



Before we had three boilers and could not control 

 temperatures as easily as we can with yours. The 

 water line is steady, and it holds its steam well. 

 The little time consumed in cleaning same is wonder- 

 ful, and we are very well pleased. 



The other morning it went down to 4*^ below zero, 



and I fired the No. 46 Boiler at 11:00 P. M., had 10 



lbs. of steam on with the draft half open, the houses 



all registering 4h*^ to 52^ and the rose house CtO'^ the 



next morning.
