Real-time monitoring method for thermal efficiency and gas characteristics of gas boiler

Abstract

The invention discloses a real-time monitoring method for the thermal efficiency and gas characteristics of a gas boiler. According to the method, basic gas characteristics are amended through real-time operating data of the boiler, so that real-time gas characteristics are obtained and applied to the calculation of the thermal efficiency of the gas boiler, and the real-time on-line monitoring of the thermal efficiency and the gas characteristics of the boiler is realized. The real-time monitoring method overcomes adverse effects caused by fluctuation of the gas characteristics on the calculation of the thermal efficiency of the boiler and is more accurate than a traditional method in which the thermal efficiency of the boiler is calculated by testing the gas characteristics regularly; an expensive on-line analyzer is not required to be additionally added on site, and the real-time monitoring method can be realized by fully utilizing existing conditions of a power plant and has good implementability and operability; and boiler operators can be guided by results in real time for optimization and adjustment, the economic operation of the boiler is facilitated, and the purpose of energy conservation and consumption reduction can be achieved.

AI Technical Summary

Problems solved by technology

Since the characteristics of the gas inevitably fluctuate within a certain range, and there are problems such as sampling representativeness and sampling errors in sampling analysis, the use of regular test data cannot truly reflect the real-time characteristics of the gas entering the furnace, and it will inevitably cause distortion of the results when used for real-time calculation of boiler thermal efficiency.
