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.
