    影响冷凝锅炉管网输送效率的因素有三个,即保温、泄漏和水力失调造成的热损失,其中因外管网水平失调和供暖系统垂直失调而造成的热损失十分可观。

    There are three factors that affect the transmission efficiency of condensing boiler network, namely heat loss caused by insulation, leakage and hydraulic maladjustment. The heat loss caused by the imbalance of the external network and the vertical imbalance of heating system is considerable.

    提高燃煤供热供暖系统的两个效率(即锅炉效率和管网输送效率)是落实节能的关键,而严格按照相关的要点来实现机器设备的合理利用才能够获得更好供暖效果并且提高设备的运转效率,而消费者想要更加可靠的提高冷凝锅炉供热的效率也应遵循此原则。

    Two to improve the efficiency of coal-fired heating system (i.e. boiler efficiency and efficiency of pipeline) is the key to implement energy-saving, and in strict accordance with the relevant points to achieve the rational use of equipment to obtain better heating effect and improve the operation efficiency of the equipment, and consumers want more reliable and improve the efficiency of condensing boiler heating should also follow this principle.

    冷凝锅炉效率不是单台锅炉的额定效率,而是冷凝锅炉组(群)的季节效率。为了提高季节效率,要尽量减少供暖期内各冷凝锅炉的启、停次数和待机时间。

    The efficiency of the condensing boiler is not the rated efficiency of the single boiler, but the seasonal efficiency of the condensing boiler group (Group). In order to improve the seasonal efficiency, the number of start and stop and standby time of the condensing boilers should be reduced as far as possible during the heating period.

    而这是因为每次锅炉启、停都要经过吹扫来消耗热量;而待机时间内冷凝锅炉就相当一个大散热器也会造成热量的损失。而为提高锅炉组(群)的季节效率,设计的选型配置至关重要,选型时需要考虑如何锅炉的组合具有较好的变负荷调节能力及促进锅炉的最小出力尽量与最低负荷相匹配。

    This is because every time the boiler starts and stops, it will consume heat by purging. During the standby time, a large radiator will also cause heat loss in standby time. In order to improve the seasonal efficiency of the boiler group, the design and configuration is very important. When selecting, we need to consider how the boiler combination has better ability of variable load regulation and promote the minimum output of the boiler to match the lowest load.

    冷凝锅炉的外管网的水平失调和室内供暖系统的垂直失调损失的热量所占比例很大因此想要提升冷凝锅炉的效率则必须改进管网输送效率。如今能源的成本高,减少冷凝锅炉管网失调热损失显得十分重要。为减少管网热损失,冷凝锅炉应采用水力平衡系统和室温调控系统。

    The horizontal imbalance of the outer pipe network of the condensing boiler and the heat loss of the vertical imbalance of the indoor heating system account for a large proportion. Therefore, the efficiency of the transmission network must be improved if we want to improve the efficiency of the condensing boiler. Nowadays, the cost of energy is high, it is very important to reduce the heat loss of the condensing boiler pipe network. In order to reduce the heat loss of the pipe network, a hydraulic balance system and a room temperature control system should be adopted in the condensing boiler.
