What should I do after the gas hot water boiler bursts?

First, the cause of blasting water wall tube blasting
       1. The material is unqualified and the installation does not meet the requirements of the specification. If the pipe wall is stratified, the weld quality does not meet the grade requirements, and there are remnants in the pipe. Causes the tube wall to be partially overheated and burned out.
       2. The quality of the feed water does not meet the standard requirements, causing fouling of the pipe wall structure and affecting heat transfer. Causes the tube wall temperature to overheat and blast.
       3. The fly ash is seriously worn, and the thickness of the pipe wall is reduced.
       4. The fire rises too fast or the furnace is stopped too fast, and the tube is unevenly heated and the weld is broken.
       5. Boiler explosion may occur due to excessive boiler load, uneven combustion and serious coking outside the pipe.

Second, prevent explosion control measures
       1. Before the installation, the pipe should be strictly re-examined, and the welding must have a welding procedure guide, and the welding quality meets the design requirements. After the pipeline is installed, pass the ball through the ball to ensure that the pass rate reaches 100%.
       2. Strengthen water quality management, soften water once per shift and meet water quality standards, regularly check scale content and eliminate it, and regularly discharge pollutants.
       3. The water wall tube and the convection tube should be inspected regularly. It is found that the tube with deformation or thinning should be replaced in time. At the same time, attention should be paid to the quality of the inspection, which must meet the requirements of the specification.
       4. The boiler should not be overloaded (specified limit), pay attention to the combustion process in the furnace, and ensure that the combustion is uniform and stable.
       5. Pay attention to the pipe coking situation, to achieve timely focus and pay attention to leakage.
