Abstract
The utility model relates to a furnace temperature automatic-control device for a gas furnace, which is arranged between the furnace and a burner. An air supply pipeline and a gas supply pipeline are connected to the burner. A ball valve is arranged on the gas supply pipeline. The device comprises a thermocouple and a programmable logic controller (PLC), wherein the thermocouple is arranged in the furnace; an electrically operated valve is arranged on the air supply pipeline; the gas supply pipeline has a dual-channel structure; a large-drift diameter electromagnetic valve is arranged on one channel, and a small-drift diameter electromagnetic valve is arranged on the other channel; and the thermocouple, the electrically operated valve and the two electromagnetic valves are communicated with the PLC. The device reduces the labor intensity, greatly improves the working efficiency, and compared with manual control, saves the gas consumption by 4 to 6 percent and greatly saves the production cost.
Description
Technical field
The utility model relates to a kind of combustion gas heating furnace kiln plant, relates 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.
The utility model content
The utility model 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.
The technical solution of the utility model 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, described device comprises thermocouple, PLC control device, described thermocouple is arranged in the stove, air supply line is provided with motor-driven valve, described steam line is a channel structure, 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 utility model 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, improved operating efficiency greatly, and compare manual control and save gas consumption 4%-6%, saved production cost greatly.
