Abstract
The invention relates to an automatic control device for the furnace temperature of a natural gas furnace. The device is arranged between the furnace and a burner nozzle; an air supply pipeline and a gas supply pipeline are connected onto the burner nozzle; a ball valve is arranged on the gas supply pipeline; the device comprises a thermocouple and a PLC (Programmable Logic Controller); the thermocouple is arranged in the furnace; an electrically operated valve is arranged on the air supply pipeline; the gas supply pipeline is of a double-channel structure, wherein one channel is provided with a large-diameter solenoid valve, and the other channel is provided with a small-diameter solenoid valve; and the thermocouple, the electrically operated valve and the two solenoid valves are connected with the PLC. According to the invention, not only is the labor intensity reduced, the working efficiency greatly improved, but also the gas consumption can be saved by 4 percent to 6 percent compared with that of the manual control, so that the production cost is greatly saved.
Description
Technical field
The present invention relates to a kind of combustion gas heating furnace kiln plant, relate in particular to a kind of combustion gas furnace kiln temperature automatic control device.
Background technology
At present, temperature controlling generally adopts the aperture size of manual adjustments burnt gas valve and air feed valve in the stove stove of combustion natural gas, regulates the fired state of burner, promptly controls the height of temperature manually.Because combustion position can not be in time understood in control manually, thereby is easy to cause the ratio of combustion gas and wind inharmonious, causes non-complete combustion of fuel, be difficult to guarantee the process curve of intensification.This combustion system not only labor strength is big, and product quality can not get guaranteeing, and fuel consumption is big.
Summary of the invention
The present invention is in order to overcome the above problems the combustion gas furnace kiln temperature automatic control device that a kind of energy savings, automatic control, high efficiency are provided.
Technical scheme of the present invention is: described device is arranged between stove and the burner; Be connected with air supply line and steam line on the burner, steam line is provided with ball valve, and described device comprises thermocouple, PLC control device; Described thermocouple is arranged in the stove; Air supply line is provided with motor-driven valve, and described steam line is a channel structure, and a passage is provided with big bare sizing electro-magnetic valve; Another passage is provided with little bare sizing electro-magnetic valve, and described thermocouple, motor-driven valve and two magnetic valves communicate with the PLC control device.
The present invention utilizes the PLC controller to control automatically the magnetic valve aperture size on the burner according to the temperature of thermocouple conduction; To the burner combustion state with carry out programme-control burning time; This combustion system has not only reduced labour intensity; Improve operating efficiency greatly, and compared manual control and practice thrift gas consumption 4%-6%, practiced thrift production cost greatly.
