The right to buy a small gas steam boiler bank tube expansion procedure, you will be taught three points! Many small and medium enterprises in the purchase of small gas steam boiler will always encounter do not know how to judge the quality of its authenticity Di distress, then, as a boiler manufacturer, summarizes three elements, for your reference is optional. 1, the amount of evaporation depends on the capacity of the boiler should be near the boiler far-reaching effects of steam or by heat produced zui. Production of steam consumption zui good about 80% of the rated boiler evaporation. Since loss such as a pipe, boiler scale, soot and other phenomena will deviate from the ideal operating conditions boiler. The need for additional reminder, evaporation is the evaporation of the boiler under high pressure, and some foreign boiler that evaporation is zero amount of evaporation reduction, the actual boiler output vary greatly. 2, when the boiler water temperature when the same amount of evaporation, due to the different water temperature, the actual boiler evaporation is different. For example: 20 ℃ 100 deg.] C water temperature and water temperature have large difference. When the boiler feed water reaches the boiler when the temperature is 20 ℃ output of a 114% 100 ℃. 3, the pipe resistance rated steam pressure of the boiler should be greater than the sum of a boiler for the steam production required for the pipeline resistance and operating pressure. If you do not meet this condition, it is not right for you, please do not ignore this point the steam pipe resistance, because the higher rated steam pressure, its saturation vapor temperature is higher. For the purchaser, you once you have these three points, basically you can buy your ideal device. In the hope that our guide, you can choose the right small gas steam boiler.

The price depends on what fuel hot water boiler bank tube expansion procedure and can install a controller? Hot water boiler fuel, its price determining factor, is what? On this kind of boiler, you can install PC-style boiler controller? And, for this kind of boiler fuel hot water boiler, what we need to know and master? Now, the problem is enumerated, then the following, without further ado, immediately give the correct answer to their right, good for everyone answering questions. 1. The price of oil hot water boiler, its determinants What? This kind of boiler fuel hot water boiler, which both belong to oil-fired boilers, hot water boilers can also belong. Its prices, in general, by tonnage and type of the boiler to the decision, because these are two important and critical factors, but also there may be some others. Tonnage and its parameters in the estimation, and should be based on actual demand, to.
