Fast boiler, condensing gas boiler leader!
Note that, these condensing boiler cleaning errors occur frequently in many condensing boilers manufacture, transport and installation in a variety of situations will occur, so that the pipe wall boilers accumulate a large amount of dirt or other impurities in the oxide, resulting in the initial boiler run directly heating surface corrosion damage. To this end, boiler manufacturing companies will configure a set of operating instructions for each condensing boilers, including cleaning this one. Then the process consumers condensing boiler cleaning in which errors can strayed, how to avoid it? A chemical cleaning process does not detect the chemical analysis is a very rigorous chemical cleaning process. But if chemical cleaning is not complete, some dirt is not completely clean; and if the cleaning time is too long, there will be over-wash phenomenon; good cleaning effect, a secondary cleaning will waste of raw materials, and waste time. Which will increase the erosion had washed condensing boiler, condensing boilers metal pressure caused by a reduced ability of the normal operation of condensing boilers after impact. Improvements are: chemical analysis must be prepared to detect chemical cleaning processes, test once every tens of minutes acidity, total iron ion concentration, PH value. When two close data laboratory analysis, chemical cleaning end point is reached, and be discharged after reaching the neutral acid. Second, chemical cleaning is not performed after completion of the passivation process is the process of passivating the clean surface of the condensing boiler deactivators re reaction. Since the control point passivated more stringent requirements, if not properly controlled, the passivation will fail, and if the pickling is completed, and only a simple cleaning is finished, which makes the surface to be cleaned boiler condensate prone to two secondary rust, scale condensing boiler capacity decreases, prone to rust improvements: condensing boiler after pickling, passivation must be rinsed, since the passivation more stringent requirements, thus rinsing process must be strictly controlled total iron ions concentration. After rinsing is complete, iron ions tested meet the requirements, the PH value immediately adjusted to strongly basic, and the passivating agent is added, warmed passivation. It can be learned from the above, chemical cleaning condensing boiler there are more abnormal phenomena, and that the life of the condensing boiler, safe operation, energy production had a negative impact, therefore, in order to eliminate these abnormal phenomena, sustainable development and safe use of condensing boilers environment has a very big role.
Consists of a shell wrapper plate to which is welded ( or for later designs riveted, end plates.. Pressure is naturally container in the shell plate due to is cylindrical design. The flat end plates, however, must be 'stayed' to prevent buckling and distortion. The combustion chamber is of similar section and is also 'stayed'.
Resistance in convective heat transfer from the water side fouling into the boiler water For the conductive heat transfer the resistance is governed by the thermal conductivity of the material (constant) and the material thickness.Learn More
Because hot water will only rise very slowly, this type of delivery system requires a pump to circulate the water from the boiler to the radiators. As in steam delivery boilers, once the water has given its heat to the air, it returns to the boiler to be heated again. View & Shop All Gas Fired Hot Water Boilers . Maintaining EfficiencyLearn More

Per my earlier post about a gravity hot water conversion to a sealed circulated system. I have another question about the correct temperature setting for boiler itself. I have read that around 180 degrees may be a typical setting for the boiler control, but during my investigations into this system, I noticed that they had it set at 200 degrees.Learn More
A heater element is essentially resistive, converting electric current to heat. Any reactive component is incidental and is low enough to be safely ignored. The necessary resistance depends on two factors - the supply voltage and the desired power. This will also dictate the supply current, which has to be in a safe range.Learn More
