The Finite Difference Method Applied for the Simulation of the Heat Exchangers Dynamics
Original language description
Heat exchangers that transfer energy from flue gas to steam are important units of thermal power stations. Their inertias are often decisive for the design of the steam temperature control system, In this paper, the analysis and the simulation of the dynamics of the steam superheater are discussed. Superheater is simulated as a unit of a control loop that generates steam of desired state values. There are many types of steam superheaters. In this paper, the steam superheater of the counterflow heating arrangement is presented as an example. The flue gas is the product of combustion of fuel. The heated medium is saturated steam, generated by the evaporating part of the boiler. To simulate the steam superheater on the computer, the exchanger is describedby the set of partial differential equations. The equations are then solved numerically by modified finite difference method. Discussion of method and qualitative and quantitative results are presented.
