Urgent help needed: technical competition on horizontal temperature measurement and analysis

Thread Content

The company is organizing a technical competition; I passed the theoretical part, and now I have to take the practical test. The unit will select two rows of horizontal temperatures; an obstacle will be placed on each side of the machine and focal area. It is required to measure these values, plot curves, and analyze the reasons behind them as well as find solutions. The curve will definitely be jagged; it’s not certain whether there will be a contrast on the machine focus side. A coke oven is used to burn blast furnace gas; it operates in pairs. The only thing that comes to mind is tampering with the amount of gas and air, such as turning off the gas valve. The things that come to mind at the moment are the following: Factors affecting the horizontal temperature curve include a gas valve that isn’t opened fully or is opened only to a limited extent, small orifice plates, and inconsistent exchange strokes, all of which result in insufficient gas supply. According to the principle of comparing the current reading with those from previous pairs, both the current temperature and those of the previous pairs are low, and the curve appears serrated. Due to insufficient gas supply, when the viewing port cover is opened, negative pressure may exist in the viewing port. Abnormal air flow can also be caused by issues such as debris on the air cover plate or blockages, which lead to the absorption of large amounts of air during descent, thereby affecting the exhaust flow of waste gases and consequently impacting the temperature. Check whether the swap sequences are consistent. Check whether the dimensions of the air inlet openings are normal. Check whether the opening degree of the damper in the flue branch of the exhaust gas manifold is normal. Also, how can one tell whether the low temperature is caused by insufficient gas and air supply? When the amount of gas is low, negative pressure will occur at the viewing port; when there is insufficient air, a banging sound will be heard when the viewing port is opened. Could everyone please help me check if my analysis is correct and if there is anything else that needs to be added?
