Mathematical Model of Hot Water Boiler and its Experimental Validation

Abstract

Low efficiency of isolated heat supply systems based on coal-fired hot water boilers requires the search of feasible control systems reducing incomplete combustion and exhaust heat losses. The paper considers a mathematical model enabling to calculate burned coal weight and boiler efficiency by a measurement set of various parameters. The proposed model is successfully validated on an experimental unit simulating a heat supply system and can be used to develop various control systems for hot water boilers, including adaptive ones.
