Problems solved by technology

As a boiler widely used in central heating, power generation and other industries, the oven is an important link to ensure the quality of the boiler. The flue gas oven method currently used is generally controlled by manual operation, with slow feedback and low adjustment accuracy. It often causes a large temperature deviation, and the quality of the boiler oven is difficult to guarantee

Embodiment 1

[0021] This system adopts the PID control program with fuzzy self-tuning, when the cycle of digital control is infinitely small, it is close to continuous control. Embed the control algorithm of fuzzy PID into the design of PLC, and optimize the selection of input and output components, electrical protection devices, alarm and display components: the programmable controller host CPU module uses XC3-24R-E type, the analog The output module is XC-E2DA, the digital display instrument is a 7-inch TH765-N touch control display screen, and the temperature sensor is a K-type armored thermocouple.

[0022] The fuzzy PID controller is designed for the control characteristics of the furnace temperature, and the control of the furnace temperature is mainly realized by adjusting the oil supply of the valve. At the same time, in order to avoid the frequent action of the furnace temperature regulator. When the furnace temperature changes little, the furnace temperature deviation does not p...

Abstract

The invention discloses an automatic control system of a smoke oven. By using hearth temperature as a control object, split control of temperature is realized by controlling the oil quantity amount and the wind feeding amount. A control interface of a touch screen is arranged according to a main work area of the oven. According to the system provided by the invention, centralized control of automatic collection of oven parameters and oven process can be realized, so that precision of temperature control is improved, the manpower is reduced, and meanwhile, fuel waste caused by temperature fluctuation can be reduced.

Description

technical field [0001] The invention relates to the technical field of oven automatic control, in particular to an automatic control system for flue gas ovens. Background technique [0002] With the development of science and technology, thermal energy and electric energy have become the most common energy sources that benefit people's lives. As a boiler widely used in central heating, power generation and other industries, the oven is an important link to ensure the quality of the boiler. The flue gas oven method currently used is generally controlled by manual operation, with slow feedback and low adjustment accuracy. It often causes a large temperature deviation, and the quality of the boiler oven is difficult to guarantee. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic control system for flue gas ovens, which can realize the automatic collection of oven parameters and the centralized control of...
