Abstract
The invention discloses a boiler ignition method, which comprises the following steps of A, performing plasma treatment on air or oxygen to generate a plasma torque by virtue of a microwave-source plasma generation device; B, igniting a boiler fuel by virtue of the plasma torque. According to the method, the microwave-source plasma generation device is used for generating the high-temperature plasma torque, and the high-temperature plasma torque is used for instantly igniting the boiler fuel, and preserving heat and supporting combustion during the low-power running of a boiler, so that the boiler fuel can be completely combusted after being ignited and during the low-power running of the boiler, the production of pollutants such as sulfur dioxide, carbon monoxide and a great amount of dust is reduced and even avoided, environmental pollution caused by a thermal power plant is reduced, and the boiler ignition method is consistent with a current environmental protection concept.
Description
Technical field
The present invention relates to a kind of ignition of the boiler method.
Background technology
Existing large and medium-sized Industrial Boiler, most of thermal power plant etc. adopt coal as fuel, and when using coal to burn for the energy, general fuel oil or combustion of natural gas, the high-voltage arc plasma flare etc. of adopting is lighted a fire.During boiler low power run, in body of heater, temperature is lower, and coal can not maintain and burn completely, now also needs to adopt fuel oil or natural gas to carry out combustion-supporting, also has minority to adopt high-voltage arc plasma torch to carry out combustion-supporting.
When ignition of the boiler or low power run, in body of heater, temperature is lower, burning of coal can not maintain maybe can not burn completely, fuel oil or natural gas is adopted to carry out combustion-supporting, now can produce a large amount of fume pollutions, now can not open dedusting and desulfurizer again, above-mentioned situation is the greatest contamination source in current boiler combustion; Although the pollutants from cooking fume produced when adopting high-voltage arc plasma ignition can reduce ignition of the boiler and low power run in a large number, but because high-voltage arc plasma characteristics is discharged by high-field electrode to produce plasma flare, there is the shortcomings such as power consumption is large, electrode life short (general at 100-200 hours at present) poor stability in the plasma generator of this mode, normally produces bring a lot of difficulty to boiler.The invention provides a kind of new ignition of the boiler mode for this reason.
Summary of the invention
In order to solve the problem, the invention provides a kind of ignition of the boiler method.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of ignition of the boiler method, comprises the following steps:
A, gas carried out plasma process by microwave source plasma producing apparatus and produce plasma flare;
B, by plasma torch boiler oil to be lighted and boiler low power run time to carry out insulation combustion-supporting.
Described gas is set to oxygen or air.
In described steps A, plasma torch temperature is set to 1500 DEG C-2000 DEG C.
The invention has the beneficial effects as follows: this method sends high-temperature plasma torch by microwave source plasma producing apparatus, instantaneously boiler oil to be lighted by high-temperature plasma torch and to carry out insulation when boiler low power run combustion-supporting, boiler oil is made to light rear and can burn completely when boiler low power run, reduce the generation even avoiding the pollutants such as sulfur dioxide, carbon monoxide and a large amount of dust, reduce thermal power plant to the pollution of environment, meet current environmental protection concept.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is schematic diagram of the present invention.
Detailed description of the invention
With reference to Fig. 1, the present invention is a kind of ignition of the boiler method, comprises the following steps:
A, air or oxygen carried out plasma process by microwave source plasma producing apparatus and produce plasma flare;
B, by plasma torch boiler oil to be lighted and boiler low-power time to carry out insulation combustion-supporting.
Wherein, in steps A, plasma torch temperature is set to 1500 DEG C-2000 DEG C.
This method sends high-temperature plasma torch by microwave source plasma producing apparatus, instantaneously boiler oil to be lighted by high-temperature plasma torch and to carry out insulation when boiler low power run combustion-supporting, after boiler oil is lighted and can Thorough combustion when boiler low power run, reduce the generation even avoiding the pollutants such as sulfur dioxide, carbon monoxide and a large amount of dust, reduce thermal power plant to the pollution of environment, meet current environmental protection concept.
Above-described embodiment is preferred version of the present invention, and the present invention also can have other embodiments.Those skilled in the art also can make equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and these equivalent modification or replacement are all included in the scope set by the application's claim.
