Boiler anti-burning dry safe operation method

Abstract

The invention discloses a dry burning-resistant safe operation method of a boiler. The dry burning-resistant safe operation method comprises a normal operation method and an operation method during unexpected power cut; the operation method during the unexpected power cut comprises opening a first valve when a thermometer shows that temperature of a heating chamber is higher than 75 DEG C; opening a second valve and an emptying valve to enable water in a dry burning-resistant water tank to flow into the heating chamber, water and steam in the heating chamber to flow to a heat exchanger shell after flowing through a safety valve, and finally, flow into a water storage pond; working personnel performs the following two operations during the unexpected power cut: (1) observing the thermometer, and when the thermometer shows that water temperature of the heating chamber is lower than 50 DEG C, closing the second valve; and after the water temperature rises to 75 DEG C or above, opening the second valve again; (2) when a liquid level in the dry burning-resistant water tank is 1 / 3 lower than the height of the dry burning-resistant water tank, opening a third valve and the emptying valve to enable water in a water-replenishing tank to be injected into the dry burning-resistant water tank. The dry burning-resistant safe operation method disclosed by the invention is capable of preventing pressure in the boiler to be overhigh when the unexpected power cut occurs and preventing dry burning, and steam contamination cannot be generated to a working site.

Description

technical field

[0001] The invention relates to the technical field of boiler safety production. Background technique

[0002] With the development of economy and society, boilers have been widely used in society. Boilers heat cold water into steam or high temperature water. The hot water or steam generated in the boiler can be directly used in industrial production and people's daily life, and can also be converted into mechanical energy through a steam power device, or converted into electrical energy through a generator. Boilers that provide hot water are called hot water boilers, which are mainly used in daily life, and also have a small amount of application in industrial production. Boilers that generate steam are called steam boilers, often referred to simply as boilers, and are mostly used in thermal power stations, ships, locomotives, and industrial and mining enterprises.

[0003] During the production process of the boiler, it is necessary to maintain the balan...

[0040] figure 1 and Figure 7 The direction indicated by the middle arrow is the flow direction of the fluid.

[0041] Such as Figure 1 to Figure 7 As shown, the safe operation method of the boiler for preventing overheating and dryness according to the present invention is implemented by the boiler for preventing overheating and dryness for safe production.

[0042]Boiler anti-drying safety production system includes a boiler, which is equipped with a combustion chamber and a heating chamber 1 (combustion chamber and heating chamber 1 are conventional technology, the part of the combustion chamber is not shown in the figure); the heating chamber 1 is connected to the boiler water inlet pipe 2 and The boiler outlet pipe 3 and the boiler inlet pipe 2 are connected to the softened water tank 4, the top of the softened water tank 4 is connected to the soft water inlet pipe 5, the soft water inlet pipe 5 is connected to the water softener 6, and the water softener 6 is connecte...
