Investigation and Control of a Regional Steam- Distribution Network under Two-phase Flow Conditions

Lajos Szakonyi
Abstract

Measurement and simulation techniques have been developed for a two-phase flow to quantify and qualify a steam network and to determine the flow regime in the network. The development of these techniques makes it possible to create an intelligent monitoring system, which ensures that:
- By the execution of the computational model the different states of the network can be simulated;
- By using the principal of the local dynamic pressure measurement the distribution of the velocity in the crosssectionof the pipes near the measurement points can be determined;
- The mass transfer in the condense vessels can be determined in the backbone pipes;
- By using mobile communication the measured data can be transferred immediately to the monitoring system;
- Algorithms and formulas can be created to determine the quality of the two-phase flow.
