A regenerative combustion control system and its control method

Abstract

The invention discloses a heat accumulating type combustion control system and a control method. The heat accumulating type combustion control system comprises an upper industrial personal computer, a lower computer, a combustion fan regulating switch, a smoke exhaust fan regulating switch, a burner front valve, a sensor group and an igniter. Configuration software is installed in the upper industrial personal computer. The upper industrial personal computer is connected with the lower computer. The burner front valve comprises a burner front gas switch, a burner front combustion air switch and a burner front smoke exhaust switch. The lower computer is connected with the combustion fan regulating switch, the smoke exhaust fan regulating switch, the burner front valve, the sensor group and the igniter. The lower computer detects the working states of the sensor group and the igniter and transmits the working states to the upper computer; the upper computer conducts comprehensive processing according to the working states of the sensor group and the igniter and the configuration software and sends an instruction to the lower computer; the lower computer controls a heat accumulating combustor. The invention further discloses the control method of the combustion control system. The heat accumulating type combustion control system is uniform in exhaust gas temperature, good in temperature control accuracy and low in energy consumption.

Description

technical field [0001] The invention relates to the technical field of heating furnace combustion control, in particular to a regenerative combustion control system and a control method thereof, which are suitable for continuous heating furnaces, periodic heating furnaces, especially forging heating furnaces. Background technique [0002] With the rapid development of today's world economy, energy consumption is increasing day by day, as a heating furnace that consumes a lot of energy, how to improve the energy saving effect through technical improvement has become a very important indicator. The core of regenerative combustion technology is high-temperature air combustion technology. After the 1990s, developed countries began to widely adopt and popularize new combustion technology. It has high-efficiency flue gas recovery and high-temperature preheating air, and has good energy-saving and environmental protection effects. . [0003] At present, the control methods of rege...

AI Technical Summary

Problems solved by technology

[0004] 1. The regenerative control parameters are fixed and cannot be adjusted adaptively. The debugging of different heating furnaces needs to be tested continuously based on experience, which consumes a lot of time, energy and financial resources;

[0005] 2. During the heating process of the burner, the furnace pressure is prone to large fluctuations;

[0006] 3. The exhaust gas temperature of different regenerators has obvious unevenness, and it is easy to over-temperature alarm
