为解决在油田生产中燃油炉、煤炉等设备启炉困难这一问题，研制出了一种微型电加热锅炉。微型电加热锅炉的控制系统主要由水位控制系统和温度控制系统两大部分组成。三冲量微机水位控制系统主要由单片机系统、水位检测器、伺服放大器等组成，实现了用单片机对水位的三冲量控制；温控部分采用可控硅调功方式，在给定周期内改变可控硅的导通时间，就可以达到改变加热功率的目的，实现温度的自动控制。
In order to solve the problem of difficulty in starting the oil-fired furnaces and coal-fired furnaces in oilfield production, a miniature electric heating boiler was developed. Micro-electric heating boiler control system mainly by the water level control system and temperature control system consists of two parts. Three-impulse microcomputer water level control system is mainly composed of single-chip microcomputer system, water level detector, servo amplifier and so on, which realizes the three-impulse control of the water level by the one-chip computer. The temperature control part adopts thyristor adjusting power mode to change controllable in a given cycle Silicon on-time, you can achieve the purpose of changing the heating power to achieve automatic temperature control.
