加強技術標準的宣貫和發(fā)行工作。制定技術標準的目的在于運用。只有技術標準得到運用，才能發(fā)揮作用，取得效益。而技術標準的發(fā)行和宣貫工作，是技術標準運用工作的重要環(huán)節(jié)，做好技術標準的發(fā)行工作十分重要。

To strengthen the technical  Xuanguan and distribution work. The pure of formulating technical  is to use it. only with the application of technical  can the effect be played and the benefit is achieved. The technical  issue and publicizing the work, is an important part of the use of technical , good technical  issue is very important.

加熱爐的分類:

1.有純加熱爐，如常壓爐、減壓爐等；有加熱爐反應爐，如裂解爐、焦化爐等。  

2.按傳熱方式分類：有純對流式爐、輻射對流式爐和輻射式爐。

The classification of the heating furnace:

1. there are pure heating furnaces, such as ctant pressure furnace, pressure reducing furnace, and so on; there are reheating furnace reaction furnaces, such as cracking furnace and coking furnace.  

2. classified according to the heat transfer mode: there are pure convection furnace, radiant convective furnace and radiant furnace.

按爐型結構分類：有箱式爐、立式爐等。  按燃燒形式分類：底燒式爐、側燒式爐。  按供風形式分類：強制供風爐、自然供風 .

Classification of heating furnace:

According to the type of furnace type structure, there are box type furnace, vertical furnace and so on. According to the form of combustion, the bottom burning furnace and the side burning furnace. Classification according to the form of air supply: forced air supply furnace and natural supply wind.

按爐溫分布，爐膛沿長度方向分為預熱段、加熱段和均熱段。進料端爐溫較低為預熱段，其作用在于利用爐氣熱量，以提高爐子的熱效率。加熱段為主要供熱段，爐氣溫度較高，以利于實現快速加熱。

According to the distribution of furnace temperature, the furnace is divided into preheating section, heating section and uniform heating section along the length direction.

The lower temperature of the feed end is the preheating section, and its function is to increase the heat efficiency of the furnace by utilizing the heat of the furnace gas.

The heating section is the main heating section, and the furnace gas temperature is relatively high, which is conducive to rapid heating.
