一、引言我所于1981年研制成燃气辐射管,并在工业上采用,为了更好地推广应用燃气辐射管,提出如下要求:(1)改进燃气辐射管及电点火器的结构及材质,使之适用于燃气中的多种气源。即要发展中、高温燃气辐射管。(2)燃气辐射管的燃烧机理及辐射管系列化、标准化研究。(3)改进辐射管的操作运行,如研制配套的全自动程序控制系统;研制配套的火焰检测系统及巡回监测多点熄火报警系统。本文着重论述在国家专利“具有改进点火结构的燃气辐射管”(专利号CN862040510)中,所作的改进研究及天然气辐射管的
I. INTRODUCTION In 1981, I developed a gas-fired radiant tube and adopted it in industry. In order to better promote the use of gas-fired radiant tubes, the following requirements were put forward: (1) Improve the structure and material of gas radiant tubes and electric igniters. Make it suitable for a variety of gas sources in gas. That is, the development of medium and high temperature gas radiant tubes. (2) Combustion mechanism of gas radiant tubes and serialization and standardization of radiant tubes. (3) Improve the operation and operation of the radiant tube, such as the development of a complete automatic program control system; the development of a matching flame detection system and a multi-point flameout alarm system for patrol monitoring. This article focuses on the improvement research in the national patent “gas radiant tube with improved ignition structure” (Patent No. CN862040510) and the gas radiant tube
