Controlling, adjusting and remote monitoring system for fuel gas-fired boiler

Abstract

The invention relates to a controlling, adjusting and remote monitoring system for a fuel gas-fired boiler, comprising an analog-quantity sensing module, a switching signal input module, a microprocessor and a switching signal output module, wherein the analog-quantity sensing module acquires a sampling parameter signal of a monitored boiler; the switching signal input module provides a switchingsignal indicating whether the monitored boiler meets safety conditions or not; one signal input end of the microprocessor is connected with the output end of the analog-quantity sensing module, and one control input end of the microprocessor is connected with the output end of the switching signal input module; under the switching signal meeting the safety conditions, the microprocessor is used for generating a control signal according to the sampling parameter signal, and the control signal comprises an opening signal of a fuel or gas-fired regulating solenoid valve and an opening signal of a blast-volume regulating solenoid valve; and the switching signal output module is used for controlling a blast blower of a burner and a main fuel solenoid valve of the burner. The system has a function of monitoring oxygen quantity in real time, thereby accurately meeting the requirements of the boiler to various load operations; the burning of the boiler is adjusted in real time so that the boiler is always in the best burning state and in the best burning efficiency, the high efficiency for burning is really realized.

Description

Technical field: [0001] The invention relates to a boiler combustion control technology, in particular to a control adjustment and remote monitoring system for a fuel gas boiler. Background technique: [0002] At the end of the 1990s and the beginning of this century, foreign countries developed and began to use a new generation of computer electronic combustion regulation and control systems to replace the current mechanical proportional regulation combustion system. For example, Germany's Weishaupt Burner Co., Ltd. has cooperated with Siemens to develop electronic combustion control and regulation systems such as FM100 and FM200; the Autoflam combustion and control system developed by Autoflam Company in the United Kingdom is currently the most advanced oil and gas burner control in the world. Regulate the system. But the price is higher. [0003] The electronic combustion control and adjustment system can not only easily and accurately meet the requirements of the boile...

AI Technical Summary

Problems solved by technology

[0005] Since my country did not begin to use natural gas and oil as fuel for industrial boilers until the end of the last century, there are few domestic studies on electronic combustion control and regulation systems, and no relevant reports have been seen yet.
