Positive impact: fuel combustion will produce large amounts of CO2, NOX and a small amount of SO2, emissions of these substances into the atmosphere, causing the greenhouse effect and acid rain, damaging effects on the environment. At the same time condensing boiler flue gas condensing water vapor, you can easily remove these harmful substances in the flue gas, therefore, the use of condensing boilers also have important implications for the protection of the environment.

In view of the above situation, according to the running time of the equipment, the corresponding inspection scheme should be made according to the regular inspection rules of the boiler in the formulation of the inspection plan, and a certain proportion of non-destructive testing sampling should be arranged consciously. Handle the defects found in accordance with the rules until they are qualified to ensure that the equipment is running properly. The oxide scale measurement method should also be used to measure directly the geometric dimensions of the oxide scale attached to the surface of the pipe (heated surface pipe). The results can indirectly reflect the operation of the tube and the degree of damage, so as to evaluate the safety of the heating surface. Hardness and metallography of alloy materials It is necessary to test the values, especially for the hardness of high alloy martensitic steels here in P91 and P92. Metallographic examination is one of the most important means to examine the hardness of martensitic steels.
