A study of the production costs of the services of an isolated central heating and power plant at the Virginia Polytechnic Institute

The services rendered at the power plant of the Virginia Polytechnic Institute are as listed: 1. Electric energy 2. High pressure heating 3. Low Pressure heating 4. Hot soft water 5. Cold soft water. Before the first of October 1930 there were no daily records kept of the various steam, electrical and water services. Weekly or monthly readings were made on several ot the meters for computing total costs, but the information was meagre. At that time, with the assistance of Wiley and Wilson, Consulting Engineers, and Professor W. T. Ellis, of the Department of Power Engineering and Machine Design, log forms were drawn up and printed. These forms were as appended and consist of a Daily Meter and Recorder log; a Shift log; a Daily Boiler Efficiency Calculation log; a Power Plant Daily Record; and a Monthly Power Plant Report. The Daily Meter and Recorder log is made out each day by the chief plant operator and consists of the twenty-tour hour readings of the various meters. This gives the total quantities of steam to the different engines, auxiliaries and processes of the system, the boiler performance, the quantities of water used, softened and distributed, and the electric energy generated and disbursed. Three Shift logs are used each twenty-four hours, one for each eight hour shift and are kept by the operator in charge of the shift. These logs are a record of the coal burned, steam generated, blowdown, etc., treatment of water softeners and boiler feed water, oil used, and give hourly readings of pressures, temperatures and electrical data as shown by appropriate instruments. These two sets of logs were then consolidated and from them the Daily Boiler Efficiency log calculated that the engineering office might keep a daily check on the plant performance. During the eight months or observation certain changes in the form of this log were evidenced. The following form is a revision recommended.
