Abstract

The invention provides an atmosphere field control system of a heating furnace. The atmosphere field control system of the heating furnace comprises the heating furnace which comprises multiple heating segments, a sampling valve, a preprocessor, a gas densitometer, an atmosphere field controller, a system computer and a zirconia analyzer. The atmosphere field control system of the heating furnace detects the oxygen content of each heating segment in the furnace in real time, monitors, alarms and records the atmosphere of each segment in the furnace, accurately controls the burning oxygen demand according to the atmosphere in the furnace, reduces the gas consumption and the oxidation burning loss, enables the atmosphere of each burning segment in the furnace to achieve the optimal state, saves the energy source, maximizes the burning efficiency and ensures the quality of the products.

Description

technical field [0001] The invention relates to the field of heating furnace equipment, in particular, the invention relates to a heating furnace atmosphere field control system. Background technique [0002] Billets are heated at different temperature sections in the high-temperature heating furnace. In addition to making the heated billets achieve uniform temperature distribution according to the process requirements, it is also very important to reasonably control the ratio of air and fuel during the heating process. [0003] The amount of air involved in combustion is usually described by the excess air coefficient μ. μ is the ratio of the actual air volume to the theoretical air volume. In the actual production process, the value of μ is related to factors such as fuel type, combustion device form and combustion conditions. According to the excess oxygen content in the combustion products, it can be divided into strong oxidizing atmosphere and weak oxidizing atmospher...
