METHOD FOR CALCULATING OPTIMAL CLEANING CONDITION OF STEAM BLOWING OF PIPELINE

摘要

PURPOSE: A method for calculating an optimal cleaning condition of steam blowing is provided to minimize a calculation error of a design condition for the steam blowing of turbine pipeline of a thermal power plant, and reduce manpower and time for calculating the design condition. CONSTITUTION: After fixing data related to temporary pipeline of a turbine, a frictional coefficient of the temporary pipeline is calculated by selecting a node(S3). The frictional coefficient for equivalent pipeline is converted by selecting a size of the equivalent pipeline(S5). A CFR(Clean Force Ratio) of each node is calculated by selecting a drum pressure(S7). It is judged that the CFR is over 1(S8). In case that the CFR is under 1, a process is returned to the step for selecting the drum pressure. In the case that the CFR is over 1, the drum pressure, a temperature, and a steam blowing flow rate are calculated(S9).
