Abstract

The invention relates to an oxygen content distribution field continuous online analyzing device of a hearth of an industrial heating furnace and a method. A plurality of groups of nozzles are mounted on the hearth of the industrial heating furnace, oxygen sensors are respectively mounted in a downstream direction of a smoke flow on the hearth of the industrial heating furnace, each oxygen sensor is provided with a wireless data transmitting module, an upper computer is connected with a wireless receiving module and a burning control system, the burning control system controls the groups of nozzles, the oxygen sensor of each measured point transmits data via the wireless data transmitting module, the upper computer receives data via the wireless receiving module, the data are analyzed and processed by the upper computer by corresponding software, an oxygen content distribution field of the hearth is fit and displayed, the data are transmitted to the burning control system, and the burning control system controls air-fuel ratio of each group of nozzles. The oxygen content distribution field continuous online analyzing device and the method analyze the oxygen content distribution field in the hearth in a real-time and online manner, adjust the air-fuel ratio of each group of nozzles, and provide visual reference for judging leakage points of the hearth.

Description

technical field [0001] The invention relates to a continuous on-line analysis device and method for the oxygen content distribution field in a high-temperature chamber of an industrial heating furnace (1000-1400 DEG C). Background technique [0002] There are a large number of industrial heating furnaces in high energy-consuming industries such as metallurgy, machinery, and ceramics in my country, which are the main source of fuel consumption and air pollution in these industries. In order to reduce energy consumption and emissions, it is necessary to adjust the air-fuel ratio of the heating furnace burner to the optimum, so that the fuel and air can achieve the best ratio, so as to achieve the dual purpose of saving energy, reducing consumption and reducing emissions. The main means of adjusting the air-fuel ratio is to continuously detect the oxygen content in the combustion flue gas online to judge whether the fuel is fully combusted, and then dynamically adjust it throug...
