Simplified input-output temperature model for power plant energy combustion

This paper describes a simplified linear temperature model for energy combustion for power plant. Modeling methodology is a decomposition-synthetic approach. Rough type Rankine-cycle's nonlinear models are to be partitioned into two sections from steam condition: saturated and superheated one. First the simple input-output model of saturated block is calculated. The output condition of this block is one of inputs of superheated block. Next the second block is divided into many subblocks that have identical tube and thermal spec. For this tiny element, linear input-output model is to be calculated. Linear model calculating method is introduced, Each tiny model has its transfer function. By expanding tiny input-output model to total subblocks, synthetic linear models are derived. The resultant models include thermal combustion conditions, and applicable to practical engineering field.
