WITH OUR READERS ^Cenflecrea from papa 71* Electrical ( able. Thai a conversion becomes increas ingly costly ti it ptogretscs. This criti cism. I may odd, is not based on theory hut experience. Where t large supply of surplus steam is ovailoble, heaters end accumulators can be employed with advantage, but such a plant hardly falls'under the heading of a con version. Alternatively, where an eilsting steam plant can be so divided before leav ing the tailerhouie aa lo permit of one sec tion being converted to high-temperature water for space heating, the other section remaining on lleam for processing, each lection being controlled Independently, the resultant savings may justify the expendi ture. But, generally speaking, lo justify claims for substantial tarings by the use of high-tempetature water, it must be se lected at the medium In the design stage. I trust ( may be forgiven for criticising your article adversely, but I do feel that American engineer# have aomething to learn from English end Continental practice. The larger the plant, the more apparent are the advantage* of high-lempertture water, ond since the system is not yet widely accepted in America, vail opportunities esiat for developing new projects in preference to advocating conversion*. London, England C L KCMPTON Managing Director, The Hobitil Engrg Co, Ltd DIESEL-GOVERNORS from poft 7i heod centrifugal force and spring force. To reoch a new balance, engine speed must change. Suppose we reduce spring force by turning speed-adjusting screw. Fig. $, to raise speeder plug and reduce spring compression. For the reduced spring force to balance flyweight centrifugal foree in same vertical position of the flyweights as before, less centrifugal force is needed. This means less engine speed, is needed. So redueiag spring foree causes engine to run at lower speed when carrying the some Toad as before. Increasing spring force raises engine speed for the same load because more centrifugal force is needed to balance the spring. Many governors use on independent spring for adjusting speed. Any spring that resists flyweight (otee affects en gine speed at which the governor forces balance. The Independent spring, usual ly outside the governor, Is generally "softer" than the speeder spring to per mit fine adjustment of speed. Future snides will discuss many other phases of engine.governing.
