Abstract

The invention relates to the field of estimation and diagnosis on the running state of a heating furnace, in particular relating to a system suitable for testing and diagnosing the on-line heat balance of a heating furnace. The system comprises a data processing module and a heat balance analysis module, wherein the data processing module is used for acquiring data in real time, namely, acquiring furnace temperature data on each section of the heating furnace, air-gas flow data on each section, evaporative cooling water volume, water pressure, water temperature data, steam output, temperature and pressure data from a basic automatic control system by utilizing an OPC (OLE for process control) technique; a human-computer interface terminal is used for inputting other related data required by the heat balance test for the heating furnace; and the heat balance analysis module is used for calculating the output data from the data processing module based on the heat engineering theory and the law of the conservation of energy, thereby generating an intuitive data table and graph and supplying a diagnosis result and a reasonable adjusting direction for the efficient running of the heating furnace.

Description

technical field [0001] The invention relates to the technical field of evaluating and diagnosing the operation control status of a heating furnace, in particular to an online heat balance testing and diagnosing system for a heating furnace. Background technique [0002] The main technical parameters used to evaluate the production and operation status of the heating furnace are: furnace output, fuel consumption, furnace (hearth) thermal efficiency, oxidation burning loss rate, etc. In order to accurately and detailedly understand the production and operation status of the heating furnace, the fuel combustion and burnout degree of the heating furnace, various heat income and thermal expenditure, the effective utilization efficiency of the heating furnace heat energy and the recovery and utilization level of residual energy, and explore the energy-saving transformation of the heating furnace Ways and measures, you need to conduct a comprehensive heat balance test on the furnac...
