Abstract
On the basis of the insertion structure mathematical model, the modeling method for single-phase section of boilers is improved and a new modeling method - chain structure modeling method based on lumped-parameter is presented. The theoretical analysis and the simulation of the chain structure model indicate that the fluctuations of mass leaving enthalpy close in on that of distributed parameter model with two-order, two-order, and three order precision at the disturbances of heat flow rate, mass entering flow rate, and mass entering enthalpy. The precision of the chain structure model can meet the requirement of engineering well.
