A mathematical model is proposed for calculating the constructive and operational characteristics of fire-tube and fire-tube-contact storage heaters used in the industrial, potable and firefighting water processing and storage units. The mathematical model includes equations for calculating heat balance, heat transfer, radiant heat transfer, and physical and chemical properties of substances. The heat transfer in fire tubes is calculated using a generalized process characteristic that is a function of structural and parametric indicators and heat engineering criteria. An example of application of the simulation software package for designing water heaters and conducting numerical experiments in order to draw up process flow diagrams accounting for variation of operational parameters and composition of fuel gas, is presented.
