Description
Technical field
A kind of Combustion Control of Hot Water Boiler device belongs to civilian fuel-firing gas-firing type hot-water boiler technical field.
Background technology
Existing civilian fuel-firing gas-firing type hot-water boiler, when boiler is started working, the ratio of fuel and air is configured, fuel and AIR Proportional remain unchanged during boiler work, this technology is fairly simple, under the stable situation of the extraneous factor that influences combustion efficiency, can obtain reasonable combustion efficiency, but in the boiler practical work process, influence the various extraneous factors of combustion efficiency, as atmospheric gas pressure, the water content of air, fuel qualities etc. are often with environmental fluctuating, and when these factors changed, the ratio of fuel and air must respective change could keep the best combustion effect.And this to be prior art cann't be solved.
Summary of the invention
The purpose of this utility model is to provide a kind of control device of hot-water boiler burning, adjusts the ratio of fuel and air in real time according to the variation of extraneous factor, keeps the combustion efficiency of the best.
A kind of Combustion Control of Hot Water Boiler device described in the utility model, comprise signal detection and treating apparatus, the combustor controller of the signal transition of signal detection and treating apparatus output for the control signal of control gas throttle opening, it is characterized in that described signal detection and treating apparatus include the power supply to whole device power supply, with the oxygen content signal transition in the boiler last person of the institute gas is the sensor of analog signal, the amplifier that the analog signal of sensor output is amplified, with the analog-signal transitions of amplifying is the A/D module of data signal, receive the output signal of A/D module and gather the data acquisition unit of significant digits signal, to the single-chip computer control system that the significant digits signal is handled, the control signal of sending after the single-chip computer control system processing is changed into the D/A module of analog signal.
Sensor described in the utility model is the oxygen quantity sensor, and described amplifier is a voltage amplifier,
The utility model has adopted the single-chip computer control system that is solidified with FUZZY ALGORITHMS FOR CONTROL in internal memory.
The utility model can detect, handle the oxygen content in the boiler last person of the institute gas, adjusts the ratio of air and fuel, reaches the ratio of real-time control fuel and air, remains the best combustion effect.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model.
The specific embodiment
The utility model adopts the zirconium oxide-oxygen quantity sensor, gather oxygen content signal in the boiler last person of the institute gas, output signal is 10～1000 millivolts of voltage signals, voltage signal is sent into 12 standard A/D converter after standard signal amplifier amplifies, convert data signal to, data signal is admitted to the normal data collecting unit, the normal data collecting unit is gathered the valid data of oxygen content, and it is sent into the MCS51-8031 single-chip computer control system, the MCS51-8031 single-chip computer control system is according to the FUZZY ALGORITHMS FOR CONTROL that is solidificated in its internal memory, data to input are handled, draw analysis result, the discriminatory analysis result, adjust the ratio of air and fuel as need, then calculating and sending goes out to control compensating signal, compensating signal through 12 standard D/A convert to analog voltage signal import into hundred the combustor controller, the combustor controller is adjusted the gas throttle opening according to voltage compensation signal, thereby adjust the ratio of fuel and air, reach the ratio of real-time control fuel and air, remain the purpose of best combustion effect.
