necessary to keep the coils filled up to inlet pressure. If the 

 pressure drops from front to rear end of the coils then the steam 

 temperature will also drop slightly, but this probably has very little 

 or nothing at all to do with your condition. 



In the first place you will find upon investigation that you have 

 some steam supply pipes in the front end (and some of these of 

 large size) which you have not at the rear end. The return lines 

 there are small and are filled with water. This condition increases 

 your heating capacity at the front end quite a little. Next you 

 will find, unless you have a vacuum system for the removal of the 

 condensation and the air, that in nine cases out of ten an appre- 

 ciable quantity of air is lodged in the heater coil pipes, some of 

 the pipes being hot throughout and some others, adjoining the first, 

 being practically cold by comparison. The air is a good non-con- 

 ductor, and the steam cannot radiate its heat unless in actual con- 

 tact with the pipe wall. 



Frequently the coils have not sufficient inclination or drop toward 

 the rear end, so that the water of condensation cannot promptly 

 run off in a thin but swift stream. If this water covers any appre- 

 cial)lc surface of the pipe, the heat effect of the steam is reduced 

 thereby, not to the full extent of the surface so occupied, but never- 

 theless appreciably. 



Sometimes the pipes sag at some point, forming a pocket for 

 accumulation of condensate. This, in turn, reduces the effective 

 pipe surface and also the effective pipe area for the passage of the 

 steam to the lower portion of the pipe, beyond the obstruction, 

 whicli, in such case, must draw its steam from the other and more 

 free pipes, via the return header. 



Whenever a kiln is empty it will be a paying scheme to inspect 

 all pipes in each coil for sag or pockets, and the heater coils for 

 drop toward the rear end. In the case your heater coils are drained 

 by steam traps, these traps should be located at least 12 inches 

 lielow the return headers, especially if there are check valves in 

 the connections from the return headers to the steam trap, because 

 :i head of several inches of water is required to counterbalance 

 tlie weight of the movable checks in the check valves. Check valves 

 iilso sometimes develop a habit of sticking, in closed or open posi- 

 tion, especially if dirt or pipe scale is present. Hence, if you sus- 

 pect anything, remove the caps and blow out with plenty of steam, 

 the valve wide open, to get all the force you can, perhaps you will 

 be surprised. 



It is a combination of these conditions wliich may create a differ- 

 ence of as much as ten degrees between both ends of a compartment 

 kiln with an ordinary heating system, consisting of heater coils 

 made up of pipes between headers, or branch tees, as these headers 

 are called by the trade. If you can hold this difference inside of 

 5 degrees you will have little to worry about, but at any rate I 

 would kee]) after the air in the coils, and would make sur« that it 

 is thoroughly removed wlienever any fresh coil is i)ut under steam. 

 This takes a little time, but it is well spent. 



It is suggested that you enlist the co-operation of the pl:int 

 engineer in this work of investigation of the heating .system. He 

 can be of much assistance to vou. Xylos.

Each man who has been selected for an address has made a particular 

 study of the subject which he will handle and his paper may therefore he 

 relied upon as being an authoritative contribution. Each speaker, in ad- 

 vance of the meeting, will have submitted his paper to the leader of dis- 

 cussion, who. likewise being a student of the subject, will have ready a 

 worthy commentary on the matter presented by the speaker. Following 

 the lender's discussion the topic will then be further debated by attending 

 members and guests, so that ever?' viewpoint bearing on the subject will be 

 bnmght to light. Members expecting to be present should therefore make 

 notations on the program of such points as they wish to present or seek 

 information on.

 and the American Sash & Door (*ompany. Kansas City. Mo., will deliver

Lower Hardwood Rates from Southwest Effective April 13 



Ki'duced rates ()n hardwood luml)er and forest products from points in 

 southwestern territory to destinations in Central Freight Association, 

 Eastern Trunk Line and Buffalo-Pittsburgh territories will become effective 

 April 13. acconling to announcement made in Memphis April 4 by J. II. 

 Townshend, secretary-manager of the Southern Hardwood Traffic Asso- 

 ciation. 



Mr. Townshend further states that railroads in Central Freight Associa- 

 tion have finally concluded to participate in reduced rates on softwoods to 

 all points in Central Freight Association territory, including pine, hemlock 

 and cypress. The rates on these woods, he sa.vs, are to lie the same as 

 those applying on hardwoods. 



The association is working vigorously, according to Mr. Townshend. to 

 secui'e reductions in rates from Ohio river crossing, combination rates, 

 and rates to Western Trunk Line territory and to Canada. 



He states that he anticipates early participation in the reduced rales on 

 soft woods by the lines serving Eastern Trunk Line territory.
