Embodiment Construction

[0032] Below in conjunction with accompanying drawing and embodiment the present invention is described in detail:

[0033] A redundant furnace adjustment decision-making system for a tubular heating furnace according to the present invention, such as figure 1 As shown, it includes an industrial computer in the central control room, a data acquisition device connected to the industrial computer in the central control room, and a data analysis device connected to the data acquisition device. It is characterized in that: the data analysis device is connected to two sets of redundant furnace adjustment decision-making devices. The two sets of redundant furnace adjustment decision-making devices are the rule-base-based furnace adjustment strategy device and the model-based furnace adjustment strategy device respectively. The rule-base-based furnace adjustment strategy device is based on the furnace adjustment experience of field technicians. The tubular heating furnace adjustment ...

Abstract

The invention relates to a redundant furnace control decision system and method for a tubular heating furnace and belongs to the field of tubular heating furnaces; the system comprises a central control room industrial personal computer, a data acquisition device connected with the central control room industrial personal computer, and a data analysis device connected with the data acquisition device and is characterized in that data analysis device is connected with two redundant furnace control decision units, a rule-base-based furnace control strategy unit and a model-based furnace control strategy unit respectively, the rule-base-based furnace control strategy unit is based on furnace control experience of field technicians, the model-based furnace control strategy unit is based on a tubular heating furnace model, and quantitative control recommendations are given when the heating furnace runs stably. The redundant furnace control decision system is simple in structure and easy to operate; the redundant furnace control decision method has simple operation flow, provides effectively improved working efficiency and is suitable for popularization and application.

Description

technical field [0001] The invention belongs to the field of tubular heating furnaces, and in particular relates to a redundant furnace adjustment decision-making system and method for tubular heating furnaces. Background technique [0002] The furnace adjustment decision-making system analyzes the collected flue gas data and draws corresponding furnace adjustment suggestions to assist on-site technicians to adjust the heating furnace. The tube heating furnace is a multi-variable, complex working condition, time-lag, and large inertia system, in which multiple variables change frequently and are coupled with each other, such as the calorific value of air and fuel. It is difficult to meet the control requirements by using the common PID control method to control the operation of the tube heating furnace. And at present, domestic petrochemical enterprises' research on the automatic control of tubular heating furnaces still stays in the aspect of process control. The thermal e...
