燃气具燃烧自适应控制技术的研究

Study on Combustion Adaptive Control Technology of Gas Generator

本文对燃气具燃烧自适应控制技术的进一步研究,结合目前燃气热水器和壁挂炉全预混燃烧技术使用,提出一种燃烧特性与火焰电流控制技术方法研究,既可实现了结构及电路设计简单,火焰探头和燃气执行机构可以使用传统的,又通过电路上需要改变原来检测火焰电流的整流特性,将火焰电流转化为连续的信号进行大量数据测量,并建模分析及探索数据可行的演算方法来控制燃气及空气的比率,从而达到最佳的燃烧工况。这种方法可以理解为对火焰直接的信号反馈控制。需要研究的是燃烧特性与火焰电流的关系,包括对火焰电流的影响关系。

In this paper,the fuel gas combustion for the further study of the adaptive control technology,combining the gas water heater and wall hanging furnace full premixed combustion technology using,put forward a kind of combustion characteristic,research methods and the current control technology,which can realize both the structure and the circuit design is simple,flame sensor and actuator gas,can use the traditional and current through the circuit need to change the original testing rectifier characteristics of flame current can be converted to the continuous signals,the measurement of large amounts of data,and modeling analysis and exploration data feasible calculus method to control the ratio of gas and air,so as to achieve the best combustion conditions.This method can be understood as direct signal feedback control of the flame.What needs to be studied is the relationship between combustion characteristics and flame current,including the relationship of influence on flame current.
