Description

Technical Field

[0001] The utility model relates to the technical field of boiler equipment, in particular to a boiler dry-burning prevention water storage device. Background Art

[0002] When the boiler loses water supply during operation, even if the fuel input is cut off, the heat storage in the boiler will still heat the flue gas, and the flue gas will continue to heat the heating surface in the boiler. The heating surface cannot be cooled due to the loss of water supply, and finally exceeds the allowable use temperature of the metal. This situation is called dry burning. Boiler dry burning will cause permanent damage to the metal material of the heating surface, causing damage to the boiler equipment and economic losses.

[0003] To avoid boiler dry burning, it is necessary to ensure that the boiler has sufficient feed water supply until the boiler cools down to below the safe temperature. There are two main ways to avoid boiler dry burning. One is to rely on the remaining feed water in the boiler for cooling. Below the subcritical parameters, a drum boiler can be used. There is a certain amount of feed water accumulated in the drum (also called the drum) and the boiler water-cooled wall tube. When the boiler feed water pump fails, the feed water accumulated in the boiler can be relied on for cooling. The other is to set up an emergency feed water pump, which is started to replenish water to the boiler in the event of an accident. When the feed water capacity accumulated in the drum is insufficient, or for a direct-current boiler without a drum, an emergency feed water pump driven by a diesel engine is set up. When the boiler feed water pump fails, the emergency feed water pump is started to replenish feed water to the boiler until the boiler cools down to below the safe temperature. The emergency feed water pump driven by a diesel engine is not only expensive, but also in standby mode for a long time. Once it fails, it cannot be started in time, and it still cannot protect the boiler from cooling down safely.

[0004] The patent document with the publication number CN205208542U proposes a dry-burn prevention water storage device and a dry-burn prevention boiler. The device includes an economizer, a water inlet pipeline and a water outlet pipeline. The economizer is arranged in the flue of the boiler. The water inlet of the economizer is connected to the water inlet pipeline, the water inlet pipeline is connected to a water supply source, and an anti-backflow mechanism is also provided on the water inlet pipeline. The water outlet of the economizer is connected to the water outlet pipeline, the water outlet pipeline is connected to the water inlet of the boiler, and a water storage tank is also provided on the water outlet pipeline. The water storage tank is arranged outside the flue of the boiler, and the setting height of the water storage tank is higher than the setting height of the economizer. In the above-mentioned dry-burn prevention water storage device, when the boiler is operating normally, the water storage tank is only used as a water supply channel; when the boiler water supply is interrupted, the water supply in the water storage tank automatically flows into the boiler under the action of gravity, replenishing the boiler with cooling water, and effectively preventing the boiler from burning dry.
