A steam-load study of the Virginia Polytechnic Institute power plant
Creel, Robert B.; Young, Richard L. (Virginia Tech, 1936-06-15)
The VPI plant has met the load situation of the 1935-1936 heating season with a small margin of capacity. Should it have been considered necessary, as a matter of policy, to carry reserve through this heating season, 20,751 pounds per hour of steam capacity would have been lacking. To meet the maximum possible hourly-load anticipated for the 1936- 1937 heating season, it would require an increase in the present capacity of the plant of 11 percent. Considering the carrying of ample reserve, an increase of 117 percent would be necessary. In that the load has reached and passed the most economical output from the standpoint of fuel consumption, forcing of present equipment will now involve economic losses that may be used to offset the costs of a new boiler installation. The load duration curve shown in Fig. 11 will be valuable in economic studies of this type. In conclusion, the authors suggest the possibility of using capacity now latent in the plant. The building of a storage place to make dry coal available tor No.4 boiler would release approximately 6,700 pounds per hour of latent steam capacity. Further gains could be made by forcing boilers 1, 2, and 3 to higher ratings with excess air during the peak hours, while the use of a higher grade bituminous coal during the heavy heating season would also show substantial gains in capacity.
