Abstract
In responding to ASHRAE SPC 155P's interest and to provide additional evidence on a possible linear relationship between output and input of a boiler under part load conditions, the National Institute of Standards and Technology undertook to conduct a series of computer simulations utilizing a revised version of a computer simulation program, DEPAB2. This program was developed previously by NIST for commercial fire-tube steam boilers, and was modified so that it could be used to simulate the operations of a commercial fire tube hot water boiler. Actual boiler specification data from a leading boiler manufacture was used as input data to the program for the simulation study. In this paper, the computer model of a commercial hot water boiler and the actual boiler specification are described. Full and part-load performance of the simulated, commercial hot water boiler is presented. A good linear correlation between output energy and input energy is found. Based upon the correlation, a suggestion is made to reduce experimental burden in testing the performance of commercial boilers.
