    锅炉房的体量一般是根据采暖面积和生活热水用量来计算热需求总量。如果想让计算值更合理,避免选大了浪费、选小了不够用的问题,除了将建筑类型、墙体保温、通风耗热量等影响冬季供暖效果的主要因素考虑在内,还需对供暖/热水使用特征有深入了解,包括供热高峰时段及频率,每日、每月热需求差异。这些细节做得到不到位,也是可以直接反映锅炉供应商的专业性。
    The volume of the boiler house is usually calculated according to the heating area and the amount of hot water consumption. If we want to make the calculation more reasonable, avoid the problem of selecting large waste and choosing small enough to use, in addition to the main factors affecting the heating effect in winter, such as building type, wall insulation, ventilation consumption and so on, it is necessary to have a thorough understanding of the heating / hot water use characteristics, including the peak period and frequency of heating, daily, every day. Monthly heat demand difference. These details are not in place, it can also directly reflect the professionalism of boiler suppliers.

    热需求总量确定后,就可以考虑包含备用锅炉在内的设备功率和台数的选择。那设备功率该怎么选?是大功率的还是小功率的?这要根据项目热使用特征,锅炉在实际运行状态下的运行效率,以及锅炉的输出总量是否匹配用户热需求等方面来决定。
    After determining the total heat demand, the selection of power and number of equipment including spare boiler can be considered. How should the power of the equipment be selected? Is it high power or small power? This is based on the characteristics of the thermal use of the project, the operating efficiency of the boiler in the actual running state, and whether the total output of the boiler matches the hot demand of the user.
    每个项目都有各自特有的热需求使用特征,但也有频繁变化的共性。由于受到这一影响,锅炉在在实际使用过程中,大部分时间内会在额定负荷的20%~100%之间运行,否则就会出现过度供热浪费能源的现象,也就是说选择锅炉时,需重点看:
    Each project has its own unique characteristics of heat demand, but there are also commonalities of frequent changes. Because of this effect, the boiler will run between the rated load 20%~100% most of the time in the actual use process, otherwise there will be excessive heating and waste of energy, that is to say, when the boiler is selected, it needs to be focused on:
    1、锅炉能不能根据用户实际热需求精准调节输出负荷;2、在变负荷或部分负荷运行状态下,锅炉又能否保持稳定高效运行。3、部分机型检修或故障时能不能较好的维持供暖供热!
    1, the boiler can adjust the output load accurately according to the actual heat demand of the user. 2, can the boiler keep stable and efficient operation under the condition of variable load or partial load operation. 3, part of the model maintenance or failure can better maintain heating and heating!
    这三个方面是解开选大功率还是小功率疑问的关键点。
    These three aspects are the key points to solve the problem of high power or low power.
    小功率的燃气模块炉进气量的比例调节来调整功率大小,所以不存在效率衰减严重的问题,节能效果会更胜一筹。热效率值不会衰减。即使系统处于低负荷运行工况下,也不会对效率造成损失,降低能耗。在模块锅炉系统中,每台锅炉之间的状态互不影响,互为备用,如遇检修,系统功率损失小,正常供热无需中断,供热也更稳定。
    Small power gas module furnace air intake ratio adjustment to adjust the size of power, so there is no serious problem of efficiency attenuation, energy saving effect will be better. The value of thermal efficiency does not decay. Even if the system is in low load operation conditions, it will not cause losses in efficiency and reduce energy consumption. In the module boiler system, the state of each boiler does not affect each other, and each other is spare. If it is overhauled, the power loss of the system is small, the normal heating does not need to be interrupted, and the heat supply is more stable.
    国内外在模块锅炉的技术开发及应用已经有了很大的发展。当前德国威斯派集团:迪威斯派系列模块炉引进的德国领先技术,在实现用户供暖温度稳定、供暖更舒适的前提下,还让模块锅炉本体运行负荷具备了运行负荷调节功能,实现从20%~100%无级调节过程中空燃比恒定,不会造成热效率衰减,将模块锅炉系统按需供热、节能的特点发挥到更高水平。
    The technology development and application of modular boilers at home and abroad have made great progress. At present, Germany Wes group: the German leading technology introduced by the series module furnace of the dewis group. On the premise of achieving stable heating temperature and more comfortable heating, the operating load of the module boiler has the function of running load regulation to achieve constant hollow combustion ratio in the process of 20%~100% stepless regulation, which will not cause thermal efficiency. Rate attenuation, to the module boiler system on demand heating, energy saving characteristics to a higher level.
    单台模块锅炉的功率确定后,根据之前计算的供热需要的总热量,计算出台数以及备用锅炉量。
    After the power of a single module boiler is determined, the number of spare parts and the amount of spare boiler are calculated according to the total heat required before heating.
