Problems solved by technology

The data obtained in this way is only historical data, not real-time data, and cannot truly reflect the boiler thermal efficiency in the actual combustion process, so boiler operators cannot evaluate and diagnose the current boiler operating status based on the efficiency value obtained by this method, and then It cannot play the role of optimizing boiler operating parameters, improving boiler energy efficiency, and reducing coal consumption

Abstract

The invention relates to the technical field of boiler running data monitoring, in particular to an online monitoring method and system for boiler energy efficiency. The system comprises a site monitoring system, a data acquisition system, a data analysis system and a result display system. Quick, accurate and real-time recording of the running parameters of a boiler is achieved, and abnormal running parameters are found in time. The thermal efficiency of the boiler is calculated in real time based on the collected parameters, and online monitoring of the running energy efficiency of the boiler is achieved. Users can optimize the running parameters of the boiler in time based on the monitoring data, so that the combustion efficiency is improved, the running cost is reduced, and the purposes of saving energy and reducing emission of the boiler are achieved.

Description

technical field [0001] The invention relates to the technical field of boiler operation data monitoring, in particular to an online monitoring method and system for boiler energy efficiency. Background technique [0002] my country's energy structure is dominated by coal, and industrial boilers with a large volume and wide area consume a large amount of coal. It is understood that there are about 620,000 industrial boilers in use in my country, of which there are about 470,000 coal-fired industrial boilers, accounting for more than 80% of the total number of industrial boilers, and their annual consumption of standard coal is about 400 million tons, accounting for about the total coal consumption in the country. 1 / 4 of. At present, the coal-fired industrial boilers in use in my country are mainly chain grates, and the actual operating thermal efficiency is only about 65%, which is 15 to 20 percentage points lower than the international advanced level. This not only means tha...
