Abstract
A on-line monitoring system of a simulated heat-exchanger which includes a plurality of temperature sensors adapted to detect the temperatures of cold water and hot water at respective water inlets and water outlets, a flowrate detector adapted to detect the flow rate of cold water, an A/D converter adapted to convert detected temperature signals and flowrate signal into corresponding digital signals, and a microprocessor adapted to calculate total heat transmission rate subject to the data obtained from the A/D converter and to calculate the heat transmission constant of the heat exchanging tube inside the heat exchanging chamber, then to store the calculated data in a memory for use as a reference value for the calculation of a next heat transmission rate so as to further calculate the heat transmission rate and thickness of fouling of the heat exchanging tube by comparing the latest coefficient of heat transmission with the previous coefficient of heat transmission, permitting the calculated result to be shown through an output device such as a monitor, the change of coefficient of heat transmission being caused by the deposit of fouling in the inside wall of the heat exchanging tube.
