Abstract

Power boiler is an important equipment of the thermal power generating unit. At present, power station boiler is developing towards the direction of high parameters and large capacity. As the circulating blood of boiler, water vapor is paid more and more attention to the quality and the control is more and more strict. Because the water quality test results can effectively reflect the health status of the boiler and be used to guide the boiler operation, it is of great significance to inspect the water quality of the power boiler. Based on government supervision of special equipment and long-term accumulated work practice, this paper analyzes and summarizes key points that affect water quality inspection of power boilers, such as test items and timing, sampling link and sample preparation, test process, and supply water quality control, and confirmed the following conclusions: (1) In the process of water quality inspection of power boiler, attention should be paid to a series of factors that are easy to affect the inspection results in the sampling, sample preparation and inspection and testing process; (2) For the medium-pressure boiler of 3.8~5.8 MPa, there is a lack of test items and test indicator of supplemental water. The author believes that the quality of supplemental water is the source of water vapor quality and should be controlled. (3) When determining the test results, if there is no hydrogen ion exchange column set up in the sampling device, the hydrogen conductivity value will not be used as the basis for determination, and other parameters will be used for comprehensive consideration; (4) When determining the test results, it is more reasonable and unambiguous to interpret "exceeding the first-level treatment value" in GB/T 12145-2016 as "reaching the second-level treatment value or above"; (5) When determining the test results, it is suggested to determine the dissolved oxygen content of boiler feed water according to the index of reductive total volatile treatment when adding ammonia and other reducing agents (such as ascorbic acid and dimethyl ketone oxime, etc.) to the water.
