捷克机组的出力和系列如下:11万瓩机组采用自然循环汽包炉;20万瓩机组采用直流锅炉;设计中的50万瓩机组采用复合循环锅炉,这台锅炉可以在15～100%负荷范围内连续运行。锅炉连续运行的最低负荷已不像11万和20万瓩机组上那样,受到蒸发管圈冷却的限制,而是取决于炉瞠中燃烧的稳定性和火焰的充满度。若燃烧没有足够的稳定性,就可能沿炉膛高度和炉膛同一截面上产生很大的热力不均匀性。而蒸发管圈的冷却在所有运行工况下都是确保的。 The output and series of the Czech units are as follows: 110,000 units are natural circulation drum units; 200,000 units are DC boilers; 500,000 units in the design are combined circulation boilers, which can operate in the 15-100% load range Continuous operation. The minimum load for continuous boiler operation is not as limited by the evaporative tube cooling as in the 110k and 200k units, but depends on the stability of combustion and the fullness of the flame in the furnace. If the combustion does not have sufficient stability, it is possible to produce large thermal inhomogeneities along the furnace height and the same cross-section of the furnace. Evaporator coil cooling is guaranteed under all operating conditions.
