对锅炉的经济运行,除提高锅炉热效率外,对并列运行的锅炉怎样科学地分配负荷,才能实现最大的节约能源,尚未引起广泛重视。目前,有些单位对并列运行的锅炉分配负荷仍是用:(1)按锅炉的热效率分配负荷,即热效率高的带满负荷,热效率低的带低负荷,但这种分配负荷的方法,不是多台锅炉并列运行时最经济的分配方法;(2)按照锅炉的经济负荷分配,即按照每台锅炉的经济负荷分配,这种分配方法也不是最经济的。最经济的分配方法是按锅炉的等微增率分配负荷。现以两台同型号的75吨/时中压锅炉为
The economic operation of the boiler, in addition to improving the thermal efficiency of the boiler, how to allocate the load scientifically to boilers operating in parallel can achieve maximum energy conservation and has not drawn much attention. At present, some units distribute the load to the boilers running in parallel with each other: (1) The load is distributed according to the thermal efficiency of the boiler, that is, the load with low thermal load and the full load with low thermal efficiency, but the method of allocating load is not more The most economical method of distribution when the boilers are run in parallel; and (2) the distribution method is not the most economical in terms of the economic load distribution of the boilers, ie according to the economic load distribution of each boiler. The most economical method of distribution is to distribute the load at equal increments of the boiler. Now with two of the same model of 75 tons / hour for the pressure boiler
