chick list of steam boilers
Land and marine boiler with a boiler and why the difference between the indoor temperature: the boiler this important product website and keywords, I believe we will not feel strange, because has been engaged in learning and mastering the knowledge in this area, in order to let yourself become familiar and understanding of this important product, and at the same time, to correct and rational use of it, in turn, can obtain good results. 1. In the course of boiler, whether to use the indoor temperature, can save gas? In the course of the boiler, if the indoor temperature, it is possible to effectively save gas, but this is no doubt. When the indoor temperature is set at 20 degrees, the boiler reaches this temperature, it will automatically stop running, so as to achieve the purpose of saving gas. If using a heating boiler, then, it is the boiler has been running, but will increase the cost.
Condensing hot water boiler enough for the sensible and latent heat in the flue gas is completely absorbed than ordinary boilers: condensing chick list of steam boilers more environmentally friendly than conventional gas boiler, has been forced to use in Europe, and to promote our country is still in its infancy. Condensing boiler compared with ordinary gas boiler, mainly in the "condensed" word above, condensing boiler can be sensible and latent heat in the flue gas is completely absorbed, then it is how to do it?
Misunderstandings in cleaning of condensing boilers and their improvement measures
During the manufacture, transportation and installation of the condensing boiler directly supplied by the new factory, the inner wall of the condensing boiler is concentrated with oxide or other dirt, which causes the condensing boiler to be corroded by the hot surface during its initial operation. Therefore, a series of measures should be taken to ensure the cleanliness of the condensing boiler when it is installed and ready to run. So in the process of consumer cleaning, what mistakes will be misplaced, and how to use it correctly? 1. there is no chemical analysis in the process of chemical cleaning: chemical cleaning is a very rigorous process. But if the chemical cleaning is not complete, some of the dirt has not been completely cleaned; and if the cleaning time is too long, Wash phenomenon will occur; cleaning effect is not good, secondary cleaning will waste raw materials, and delay time. The phenomenon of excessive washing will aggravate the corrosion of condensing boiler, cause the metal bearing capacity of condensing boiler to decrease, and affect the normal operation of condensing boiler. The improvement measures are: must do the chemical analysis detection in the chemical cleaning process, every ten minutes to test the acidity, the total iron ion concentration, the PH value. When the two analytical data are close, the chemical cleaning reaches the end point, neutralizing the acid solution to the neutral and then discharging.
2. no passivation after chemical cleaning: passivation process is actually a clean condensation boiler body surface and passivation agent re-reaction process. Because the control point of passivation is more strict, if the control point is not well controlled, the passivation will fail, and if the pickling is finished, only simple neutralization will be carried out, and the cleaning will end, which makes the surface of the cleaned condensing boiler easy to produce secondary floating rust. The scale-inhibiting ability of condensing boiler is reduced, which makes it easy to rust. The improvement measure is to rinse and passivate the condensing boiler after pickling. Because the passivation requirement is relatively strict, the concentration of total iron ions must be strictly controlled in the rinsing process. Rinse After finishing, the pH value should be adjusted to strong alkalinity immediately after the iron ion is detected, and the passivation agent should be added to passivate the temperature.
