一、引言沈阳第三橡胶厂是轮胎生产厂，具有生产用汽量大、连续用汽且负荷极为不均、对汽压要求又十分严格等特点。为确保汽压在０．９ＭＰａ±０．０５ＭＰａ范围内，司炉工经常在负荷大时，急速增加燃烧，一般情况靠加快炉排走速，调整供风来实现减弱燃烧。在负荷小时，... I. INTRODUCTION Shenyang No.3 Rubber Factory is a tire factory with the features of large quantity of steam used for production, continuous use of steam, extremely uneven load, and extremely strict requirements on steam pressure. In order to ensure that the steam pressure is in the range of 0.9MPa ± 0.05MPa, the fireman often increases the combustion rapidly when the load is large. In general, the blast furnace speed is reduced and the air supply is adjusted to reduce the combustion. When the load is small, ...
