Example one

Referring to fig. 1, fig. 1 is a flowchart of a method for emergency handling simulation of a gas boiler fault according to an embodiment of the present invention. The embodiment of the invention provides a method for simulating the fault emergency treatment of a gas boiler, which comprises the following steps:

s100, establishing a three-dimensional virtual model of the gas boiler, wherein the three-dimensional virtual model comprises the following steps: a boiler model, a smoke and air system model and a steam and water system model;

the establishment of the three-dimensional virtual model of the gas boiler comprises the following steps: and establishing a three-dimensional virtual model of the subcritical ultrahigh-temperature natural circulation gas boiler.

Specifically, a three-dimensional virtual model can be established according to a subcritical ultrahigh-temperature natural circulation gas boiler, the established three-dimensional virtual model can comprise a boiler model, a smoke system model and a steam-water system model, and the connection relation among all devices can be established through a power plant device algorithm. The established three-dimensional model of the boiler may include: the single boiler barrel is naturally circulated, a centralized downcomer is used for reheating the middle part once, the gas furnace is arranged in a box shape, and the lower part of the boiler is a hearth; the upper part of the boiler is provided with a superheater and a reheater heating surface which are divided into a front flue and a rear flue. The front flue and the rear flue are separated by a rear wall of the upper water-cooled wall, and the top of the boiler is a ceiling heating surface. The difference is that the front wall and the side wall of the rear flue consist of membrane water-cooled walls, and the rear wall consists of a membrane wall-covered superheater. A front flue at the upper part of the boiler is sequentially provided with a screen superheater, a final superheater, a high-temperature reheater and a tertiary superheater according to the flow direction of flue gas, a rear flue is sequentially provided with a low-temperature superheater, a low-temperature reheater and a superior economizer according to the flow direction of flue gas, and a rear flue of the boiler is sequentially provided with a subordinate economizer and a tube box type preheater according to the flow direction of flue gas. The furnace water wall, the superheater, the reheater and the upper economizer are all suspended on the top plate beam, and the lower economizer and the air preheater in the tail flue are respectively suspended and supported on the rear column and the rear beam. The burner adopts a cyclone burner arranged by the opposite impact of a front wall and a rear wall, and superheated steam adopts two-stage water spraying for temperature regulation. The reheated steam is mainly regulated in temperature by adopting a recirculated flue gas mode and is assisted in a water spraying temperature regulation mode. The heating surfaces of the front vertical shafts on the upper part of the hearth are all horizontally arranged in-line tube bundles and are supported and hung by suspension tubes cooled by superheated steam, and the heating surfaces of the rear vertical shafts are all arranged in-line and are supported and hung by suspension tubes cooled by water supplied from an economizer outlet. The reheater is a pure convection heating surface, and the high-temperature reheater and the low-temperature reheater are respectively arranged in front and rear shaft flues with moderate smoke temperature levels, so that the combined type of regulating the temperature of the reheated steam by smoke recirculation and water spraying temperature reduction is more suitable. The economizer adopts an H-shaped fin economizer which is arranged in two stages, and can effectively reduce the smoke temperature at the inlet of the preheater, thereby reducing the smoke exhaust temperature of the boiler and improving the boiler efficiency.

Meanwhile, the established model of the smoke and wind system may include: cold air from a blower is fed into a horizontal tubular air preheater, after being heated by 3 return strokes, hot air passing through the air preheater is fed into a gas burner as combustion-supporting air, and after the air and the gas fed into a hearth are combusted, a large amount of hot flue gas is generated, and the hot flue gas upwards sequentially passes through a screen superheater, a final reheater and a tertiary superheater, then downwards sequentially passes through a low-temperature superheater, a low-temperature reheater and a superior economizer, and reaches an outlet flue of the economizer after being subjected to radiation and convection heat exchange. The flue gas flows downwards again, one path of flue gas enters the tubular preheater through the lower-level economizer and the inlet flue of the preheater to exchange heat with air, and finally leaves the boiler through the outlet flue of the air preheater to enter the gas heater to exchange heat with the fuel gas, so that the temperature of the discharged flue gas is reduced, and the efficiency of the boiler is improved; the other path enters a flue gas recirculation fan through a recirculation air inlet flue, then flows to a recirculation air outlet flue, is divided into two paths, enters a recirculation flue gas air box from two sides, and finally enters a hearth. The steam-water system model established may include: the main boiler water supply pipeline led from the high-pressure outlet is led into a lower-level economizer inlet collecting box from one side, heated by a lower-level economizer pipe group and then led into a lower-level economizer outlet collecting box, and then led out of the upper-level economizer inlet collecting box after being heated by the upper-level economizer pipe group, and led into an economizer hanging pipe outlet collecting box arranged above a ceiling through a water-cooling hanging pipe and then led into a boiler barrel through 2 economizer outlet guide pipes. After entering the drum, the feed water is mixed with the boiler water in the drum and then enters the water-cooled wall lower header through the downcomer and the distribution pipe. The furnace water passes through the water-cooled wall lower header and enters the water-cooled wall pipe. Boiler water may also enter the economizer recirculation tube from the downcomer during boiler start-up. The furnace water flows upwards along the water wall tubes and is heated continuously, and the furnace water flows through the following three parts of tubes in parallel: the water cooling wall hanging pipe comprises a front water cooling wall pipe, a side water cooling wall pipe, a rear water cooling wall pipe and a rear water cooling wall hanging pipe. And the steam-water mixture generated in the water wall pipe is converged in each outlet header of the water wall and then enters the steam drum through the steam-water outlet pipe. In the steam drum, steam-water separation is carried out on the steam-water mixture. And the separated steam enters the superheater system, and the separated water returns to the water-in-steam space to continue to circulate.

Step S110, selecting typical fault types of the boiler from a plurality of types of typical fault types of the boiler built in advance, wherein each type of typical fault type of the boiler at least comprises the following steps: fault phenomenon animation, fault reason animation and fault emergency processing;

The displayed fault cause animation in the boiler fire extinguishing fault type can comprise: tripping the air guide and the air feeder; sudden gas interruption or sudden pressure drop; the load of the boiler is too low, and the combustion is unstable and is not adjusted in time; the negative pressure of the hearth is overlarge due to improper air supply and gas proportion; a large amount of cold air leaks into the hearth; suddenly blasting the water wall; fire extinguishing protection misoperation; the operator has too large an adjustment range. The fault emergency processing step in the displayed boiler fire extinguishing fault types can comprise the following steps: after the boiler extinguishes the fire, the fire extinguishing protection is started, the boiler is stopped emergently, and each air door is manually closed; if the fire extinguishing protection is not operated, the emergency furnace-stopping switch is pulled by hand to process according to the emergency furnace-stopping operation steps (checking whether all the gas quick-cutting valves are closed or not); the electric door for reducing the temperature is closed, the automatic switching is manual, and the water level is controlled; opening a pipeline drainage door, reducing the induced air volume, keeping the ventilation rate in the furnace at 25% -30%, keeping the negative pressure value range of the hearth at-50 Pa to-100 Pa, keeping the ventilation time at 5 minutes and keeping the report value long; finding out reasons and eliminating the reasons, then putting the ignition burner again, igniting, keeping stable combustion, and raising temperature and boosting pressure; after the boiler is re-ignited, the steam turbine can be started according to the parameters by contacting the steam turbine. Keeping the steam temperature and the water level stable; if the reason causing fire extinguishing can not be eliminated in a short time, the fire extinguishing agent is processed according to the program after normal furnace shutdown; after the boiler is put out a fire, if gas is continuously fed or explosion can occur due to improper treatment, at the moment, fuel supply to the hearth must be immediately stopped, the air feeder is stopped, the baffle of the air feeder is closed, detailed inspection is immediately carried out on the boiler body, the fact that the heating surface and the flue at the tail part are free of fire and the equipment is not damaged is confirmed, the air feeder can be started, the negative pressure value range of the hearth is maintained between-100 Pa and-150 Pa, and the ignition can be carried out again after the ventilation is enhanced for 5 minutes to 10 minutes. After the combustion is stable, keeping larger negative pressure, checking the water-cooled wall from the fire observation hole, confirming that the inside is not damaged, and continuously boosting. Meanwhile, a scoring standard corresponding to a fault emergency treatment step in the boiler fire-extinguishing fault type can be set, for example, after the boiler is subjected to fire extinguishing in the step, fire-extinguishing protection is required to act, the boiler is stopped emergently, each air door is manually closed, and a score A1 corresponding to the step can be set; after the reason is found and eliminated in the step, the ignition burner is put into the furnace again, ignition is carried out, combustion is kept stable, and the score A2 corresponding to the step can be set for temperature rise and pressure rise.

The displayed fault cause animation in the boiler drum full water fault type can comprise the following steps: the water supply adjustment automatically fails, so that the water supply flow is increased; the indication of the water level meter, the water supply flow meter or the steam flow meter is incorrect, so that operators can make misjudgment and operate wrongly; the load of the boiler is reduced too fast, and the control of operators is improper.

Since the scoring standard corresponding to the fault emergency treatment step in the boiler drum full water fault type is the same as the scoring standard principle of the boiler fire extinguishing fault type, the description is not repeated here.

At this time, water can be slowly fed into the boiler, and after the fault is eliminated, the boiler can be ignited again. Since the scoring standard corresponding to the fault emergency treatment step in the boiler water shortage fault type is the same as the scoring standard principle of the boiler fire extinguishing fault type, the description is not repeated here.

Since the scoring standard corresponding to the fault emergency treatment step in the steam-water euthanization fault type is the same as the scoring standard principle of the boiler fire extinguishing fault type, the description is not repeated here.
