[LB025437], Letter from Charles Batchelor to Babcock and Wilcox, November 8th, 1888

Editor's Notes

Dear Sir:- In our Laboratory here, as you are aware, we have three of your 73 horse power boilers. They are set in Jarvis setting. I find my engineer, Mullica, who is supposed to be an experienced electric light man, complain very much that he cannot keep steam in these boilers, even when they are far below what their rated capacity is, as sold to us. For instance, I have had indications taken, and also weights of water evaporated, and found that even when the boilers are only generating about 130 horse power, it seems impossible for the engineer to keep up his pressure, which gradually goes from 110 down to 65 in two or three hours. If is quite possible that we are not best fitted in the shape of grates or that we have not proper arrangements for crafts, or there may be something which I do not know of and which the engineer possibly cannot tell me anything about. I write now to ask you if you could send me an experienced man to run these boiler for a day or two, in order that he may be able to show my engineer, what I believe to be quite possible - that is, to run the boilers to their full capacity and keep up steam. I think myself that this can be done by ordinary attention. Your man will also be able to tell me whether, in his opinion, we have the best arrangement for running the boilers to max capacity.##Please let me hear from you, as it is rather an important thing for me to make these boilers perfectly satisfactory to my own ideas of what they should do, and what I know we have done is other places.
