No matter whether the boiler is operated at low pressure or overloaded, it is not the correct mode of operation. The most economical and safe operation mode is still operated within the range of rated parameters and economic load, and the best results can be achieved.
In the operation practice of industrial boilers, another problem that has a relatively large impact is frequent changes in the load, which brings some problems to the operation. For example, an abnormal production at a certain factory, coupled with the reasons for scheduling, there are frequent switching vehicles, and the load is unstable. The problem is that in the case of self-generation, because steam is used for power generation, more steam power can be generated when the steam load is high, and less power is generated when the steam load is low, and the balance of power generation cannot be maintained. In the case of variable steam load, , Often formed by steam pressure changes in the increase of thermal shock and thermal fatigue of the drum, easy to cause fatigue damage, the wall of fire-resistant masonry also easily lead to cracking, resulting in increased air leakage, boiler thermal efficiency decreased. All these problems are caused by large fluctuations in the steam load. If the load fluctuations are eliminated, this problem is fundamentally solved. If there are conditions in the boiler room, the steam accumulator can be used to equalize the fluctuation of the steam load. Solve the above problem.
