Description
Technical Field
The utility model relates to a combustor technical field specifically is a shutoff type msw incineration combustor.
Background
At present, an incinerator of a garbage power plant is required to be environment-friendly, when the incinerator is started, garbage can be thrown in until the hearth temperature reaches 850 ℃, and the hearth incineration temperature must be kept above 850 ℃ all the time during the working period of the incinerator. However, due to various reasons, the calorific value of the garbage is extremely unstable, and the temperature of the hearth is often not up to the standard, so that each garbage incinerator is matched with a special burner for auxiliary heating. When the heat value of the garbage is lower and the temperature of a hearth is lower than 850 ℃, the auxiliary burner must be started immediately to carry out afterburning and temperature rise; when the heat value of the garbage is high and the temperature of the hearth can be kept above 850 ℃, the auxiliary burner stops running and is in a standby state.
When the auxiliary burner is in combustion operation, the combustion fan can be operated all the time, natural wind is continuously blown to the hearth in the burner body to be mixed with fuel of the burner for combustion to generate heat, and the auxiliary burner belongs to a normal working state; however, when the auxiliary burner stops running and is in standby, the combustion fan and the fuel are both in a stop state, no cooling medium is arranged in the burner, and thus high-temperature flue gas in the hearth can reversely enter the burner to cause damage to parts of machinery and electrical components.
The common technical route of the solution is to use a cooling system for cooling. The cooling system connects compressed air to the periphery of parts such as a main oil gun, a fire detector and the like, reduces the temperature of the parts and plays a certain role in isolating high-temperature smoke. The cooling air quantity of the method cannot be too large, the cooling of the hearth can be influenced too much, energy loss is caused, but the cooling air quantity is too small, and the cooling effect is local and limited; meanwhile, the inner space of the combustor is large, high temperature can be transmitted to the outer parts of the combustor through the metal shell, the magnetic force of a coil of the electromagnetic valve is declined, an electric circuit is aged, the sensitivity of the instrument is reduced and the like due to the fact that the time is long, the fault rate of the combustor in the operation process is obviously increased, and the maintenance cost is increased.
In addition, the working pressure of the hearth of the incinerator is also very unstable, and under normal conditions, the pressure of the hearth is negative pressure, and high-temperature flue gas generated by combustion of the hearth can flow and be discharged from the direction of the chimney; however, when the incinerator works, garbage can be uninterruptedly thrown into the hearth, the load of garbage incineration is extremely unstable, so the negative pressure control of the hearth is also extremely unstable, the positive pressure condition of the hearth often occurs at times, high-temperature smoke can flow out from the installation position of the burner when the positive pressure of the hearth occurs, sometimes even open fire is sprayed out from the installation opening of the burner, and under the condition, cooling air configured on the burner body is not enough to resist the high-temperature smoke of the hearth completely to be fire, which is fatal to the damage of the burner.
Therefore, structural measures are needed to thoroughly solve the problem that high-temperature flue gas in the hearth enters the waste incineration burner.
