Guide: After a gas-fired steam boiler has been operated for a period of time, certain dirt will be generated. These dirt need to be discharged out of the boiler within a limited time to maintain the good operation of the gas-fired steam boiler. 1. What is the purpose of the gas steam boiler blowdown? 1. Remove the suspended foam on the boiler water surface, thereby reducing the salt content and alkali content of the boiler water, and avoiding the phenomenon of co-evolution of steam and water. The gas steam boiler is running for a period of time After that, a certain amount of dirt will be generated, and these dirt need to be discharged out of the boiler within a limited time to maintain the good operation of the gas steam boiler. 1.

Gas steam boiler After a period of operation, a certain amount of dirt will be generated, and these dirt need to be discharged out of the boiler within a limited time to maintain the good operation of the gas-fired steam boiler.

　　1. What is the purpose of gas steam boiler blowdown?

　　1. Eliminate the suspended foam on the boiler water surface, thereby reducing the salt and alkali content of the boiler water, avoiding the phenomenon of co-evolution of steam and water in the boiler, and ensuring the quality of steam.

　　2, remove the dirt and sludge accumulated on the bottom of the drum and the lower header to avoid a series of problems.

　　 Two. Precautions for the blowdown of gas steam boilers

　　 1. Before the sewage discharge work, the water level in the boiler should be adjusted to the normal water level (exceeding), and the process should be strictly monitored to prevent water shortage.

　　2. After the sewage has been discharged for a period of time, check whether the temperature of the sewage pipe is abnormal, so as to check whether the sewage valve leaks. If there is, it should be dealt with in time.

　　3. For the blowdown work of gas-fired steam boilers, the three principles of frequent discharge, less discharge and uniform discharge should be followed, and the blowdown should be at least once per shift to avoid problems such as tube bursts in the boiler, which may cause serious consequences.

       4. The blowdown of gas-fired steam boiler should be carried out under the low load state of the boiler and under normal working pressure, and the switch should be operated and repeated several times, so as to ensure a better blowdown effect, and be carried out thoroughly at one time, so as not to have residues, thereby affecting the blowdown effect. And the normal operation of the boiler.
