# BOILER:STEAM

This boiler model is an adaptation of the empirical model from the Building Loads and System Thermodynamics (BLAST) program. Boiler performance curves are generated by fitting catalog data to third order polynomial equations. A constant efficiency boiler is modeled by setting the fuel use coefficients as follows: N9=1, N10=0, N11=0
