Description
Technical field
The utility model relates to a kind of boiler controlling device, specifically, has related to a kind of boil combustion control device.
Background technology
Fuel is breath of life during we live, and the burning of fuel generally needs the participation of combustion adjuvant, and the most frequently used is exactly airborne oxygen; Fuel combustion whether abundant has certain corresponding relation with its exhaust gas component that is produced; For the inadequate fuel of burning, can promote its burning through increasing combustion adjuvant, to improve the utilization ratio of fuel.
Play a part very importantly in the boiler Modern Production life, in the process of using boiler, can its employed fuel fully burn, and both has been related to the economic benefit that boiler uses, and also is related to the pollution of boiler exhaust gas to environment.
Present boiler generally all adopts the air-breathing system, is example with the large-sized boiler of fire coal, adopts the secondary supply air system as the one of which; Promptly once air-supply is a fuel air; See and carry coal dust off by primary air fan and get into boiler combustion, secondary blast is a combustion air, is seen off by pressure fan; Main effect is to supply with the enough oxygen amounts of boiler, to promote the abundant burning of fuel.
Existing boiler supply air system, the judgement of its air output size has two kinds usually: a kind of is that the oxygen scale is installed on the boiler control panel, and the operations staff is according to the indicated value of table meter; The content of carbon dioxide and oxygen in the control flue gas, and then the size of the interior excess air coefficient of control stove make it remain optimum value as far as possible; To obtain higher boiler efficiency; This method needs operations staff's real time inspection, and is higher to people's dependency degree, unreliable; A kind of in addition method is that the operations staff checks and analyze the combustible content in flying dust, the lime-ash, observes furnace flame and smoke evacuation color etc., and whether the analysis-by-synthesis inner operating is normal, and this method subjectivity is bigger, and is higher to people's degree of dependence, also unreliable.
In order to solve the problem of above existence, people are seeking a kind of desirable technical solution always.
Summary of the invention
The purpose of the utility model is the deficiency to prior art, thereby a kind of simple in structure, practical, capable of saving fuel, boil combustion control device that can reduce environmental pollution is provided.
To achieve these goals; The technical scheme that the utility model adopted is: a kind of boil combustion control device; It comprises microprocessor module, boiler exhaust gas analysis module and overfire air fan benefit air quantity controller; Wherein, the gas signal output of said boiler exhaust gas analysis module connects the gas signal collection terminal of said microprocessor module, and the air quantity control output end of said microprocessor module connects the air quantity control input end that said overfire air fan is mended air quantity controller.
Based on above-mentioned; It also comprises boiler temperature acquisition module and fuel input control device; The temperature signal output of said boiler temperature acquisition module connects the temperature signal collection end of said microprocessor module, and the fuel input control output end of said microprocessor module connects the fuel input control input end of said fuel input control device.
Based on above-mentioned, said boiler exhaust gas analysis module includes carbonomonoxide concentration detecting sensor, gas concentration lwevel detecting sensor and oxygen concentration detecting sensor.
Based on above-mentioned, it also comprises tail gas suction pump, tail gas filter, tail gas condensing unit and the tail gas sampler chamber that is connected successively, and said boiler exhaust gas analysis module is arranged in the said tail gas sampler chamber.
The relative prior art of the utility model has substantive distinguishing features and progress; Specifically, this boil combustion control device judges through analyzing the boiler exhaust gas composition whether fuel combustion is abundant; And based on fuel burning whether fully decision whether increase the oxygen-supplying amount of overfire air fan; Also the scalable fuel amount of sending into finally makes fuel as much as possible fully burn, and brings into play fuel value to greatest extent; This apparatus structure is simple, practical, can practice thrift a large amount of fuel, reduces because of the insufficient environmental pollution that produces of fuel combustion, and in addition, transplantability is strong, can be widely used in other burner.
Description of drawings
Fig. 1 is the utilization structure sketch map of the utility model.
The specific embodiment
Through the specific embodiment, the technical scheme of the utility model is done further detailed description below.
As shown in Figure 1; A kind of boil combustion control device; It comprises microprocessor module 1, boiler exhaust gas analysis module 2, overfire air fan benefit air quantity controller 3, boiler temperature acquisition module 4, fuel input control device 5 and the tail gas suction pump 6 that is connected successively, tail gas filter 7, tail gas condensing unit 8 and tail gas sampler chamber 9; Wherein, Said boiler exhaust gas analysis module 2 is arranged in the said tail gas sampler chamber 9; The gas signal output of said boiler exhaust gas analysis module 2 connects the gas signal collection terminal of said microprocessor module 1, and the air quantity control output end of said microprocessor module 1 connects the air quantity control input end that said overfire air fan is mended air quantity controller 3; The temperature signal output of said boiler temperature acquisition module 4 connects the temperature signal collection end of said microprocessor module 1, and the fuel input control output end of said microprocessor module 1 connects the fuel input control input end of said fuel input control device 5; Said boiler exhaust gas analysis module 2 includes carbonomonoxide concentration detecting sensor, gas concentration lwevel detecting sensor and oxygen concentration detecting sensor.
Tail gas suction pump 6, tail gas filter 7, tail gas condensing unit 8 and tail gas sampler chamber 9: be respectively applied for and collect dust granules, the boiler exhaust gas behind the cooling and dedusting in boiler exhaust gas, the filtering boiler exhaust gas and the boiler exhaust gas sample space is provided.
Boiler exhaust gas analysis module 2: being used for analyzing the gas componant of boiler exhaust gas, mainly is carbon monoxide, carbon dioxide, concentration of oxygen.
Overfire air fan is mended air quantity controller 3: be used for the content of microprocessor module according to exhaust gas component carbon monoxide, carbon dioxide and oxygen, confirm the blower fan power output, to change the oxygen amount of sending into, fuel metering efficiency of combustion.
