The purpose of testing used boilers is to achieve the following goals:
One. Identify and eliminate hidden dangers in time to prevent them.
Many accidents come from newly built pots or second-hand boilers. Unreasonable structure, improper selection of steel, miscalculation of strength, poor quality, etc., these are the major hidden dangers that will lead to accidents in the future. If the second-hand boiler is strengthened supervision and inspection, it can stop the gate and prevent the boiler with defects from being put into operation. In addition, the defect of running a boiler, in general, from generation to development, knowing that an explosion occurs, has to go through a process. For example, the edge of the pressure element is cracked, the pull is broken, and the corrosion and deformation of each part are not sudden. If the boiler can be planned to carry out internal and external inspection regularly, it can find defects in time, master its development trend, and take corresponding measures to prevent the occurrence of malignant accidents.
II, make up the defect, prolong the service life of damaged furnace
Minor defects in second-hand boilers, if not repaired in time, will speed up the damage and shorten the service life. Many boilers, due to the lack of regular inspections, can not be quickly discovered with defects and can not be repaired in a timely manner. The result has only taken ten years, and some have even been broken and destroyed in only three or four years.
Third, to achieve safe operation and ensure the normal progress of production
According to the operation of the boiler, carry out planned inspection; Dealing with the hidden dangers of accidents in a timely manner will not prevent the discovery of defects or accidents when the furnace is not allowed to be stopped, resulting in the forced shutdown of the furnace. At this time, the need for normal production and daily life of the people has played a role in ensuring.
Closing loopholes and saving energy
The use of fuel for boilers accounts for a large proportion of the country's annual boiler fuel accounts for 40 % of the output. Many boilers leak steam, leak water, and leak wind. Leaky smoke. Or the heat surface accumulates a large amount of scale, improper emission control, etc., wasted a lot of fuel, and the boiler does not reach the rated output. By strengthening the inspection of second-hand boilers, these loopholes can be closed in a timely manner, reducing losses and increasing output. There are more than 100,000 boilers in the country. If you do this, the fuel saved is substantial.
In addition, the boiler inspection can clear the import and export channels, improve national reputation and reduce losses, it is also very important. International requirements, boiler import and export through the relevant departments of the two countries to conduct inspection visas. If the quality of export pot protection can improve product credibility and competitiveness; Claims may be made for problems found in imported boilers.
