Gas steam generator

  After using it for a long time, we will find that a layer of scale has formed in it, which is very difficult to clean. At this time, everyone will be at a loss. So how to deal with the scale, let's take a look.

  Because the thermal conductivity of scale is very poor, its thermal conductivity is only one percent of boiler steel plate, even if there is no too thick scale, the thermal conductivity will be greatly reduced, not only wastes fuel, but also directly affects the service life of the gas steam generator. Therefore, it is said that scale is the "source of all hazards" for boilers.

  How to deal with scale:

  The electric steam generator is heated by the heating tube, so it can be removed for cleaning. The gas steam generator and the electric steam generator are essentially different. The two have different design structures and different cleaning methods.

  The gas steam generator is heated by the inner tank, but the inner tank cannot enter. If you want to enter the inner tank of the gas steam generator, the workload will be very large. Under normal circumstances, we will clean the inner wall of the tank by chemical methods.

  Due to the different water quality, the cleaning effect will be different. We usually use alkaline washing and acid washing to complete it. First, use hydrochloric acid and corrosion inhibitor in the inner tank to clean the rust and scale better, and then combine with alkaline boiling to transform sulfate and silicate to achieve complete cleaning. Although this cleaning method is simple, hydrochloric acid is corrosive to metals, so pay attention to the amount of hydrochloric acid used when using it.

  However, to take precautions and prevent problems, the use of gas steam generators lies in daily care. It is recommended to use soft water, which can effectively reduce the precipitation of calcium and magnesium ions and prolong the service life.

  The above is to show you how to deal with the scale. I hope it can help everyone. You can take care of the machine on a regular basis, so as to ensure that the machine can be used for a longer time.
