Abstract
The present invention relates to a kind of method for improving gas fired-boiler energy-conservation and stability, the interior ignition combustion gas (6) of burner hearth (3) of the gas fired-boiler (1) produces heat, the water (7) of heating boiler, placement one can be heated and can store the energy saver (5) of heat among the burner hearth (3) of gas fired-boiler (1), and calory burning heating energy-saving device (5) is lighted in combustion gas (6).Because placement can heat and can store the energy saver of heat in burner hearth, in gas fired-boiler normal work engineering, when system temperature (pressure) reaches certain setting value, burner stops working, temperature drop rate substantially reduces in burner hearth, the number of starts of burner can be thus reduced, reaches energy-saving effect；Unburned gaseous mixture is after burner is flame-out in burner hearth, still with energy saver reactive combustion, prevent the detonation or blast when it lights a fire again, energy saver plays a part of igniting and stablizes burning, steady firearm can be replaced to realize stable burning, therefore gas fired-boiler energy-saving efficiency and stability are improved with relatively simple structure.
Description
Technical field
The present invention relates to a kind of method for improving gas fired-boiler energy-conservation and stability, the gas fired-boiler is lighted a fire combustion in burner hearth
Combust gas and produce heat, the water of heating boiler.
Background technology
Rapid development and the industrialized raising of society, the reduction of coal resource and disposal of pollutants problem with economy, compel
The needs industry cut and the transition and upgrade of domestic fuel.As the important plant equipment in the national economic development, gas fired-boiler is used
Have become the necessary path of socio-economic development and environmental requirement instead of coal-burning boiler.
In the gas fired-boiler course of work, when system temperature (pressure) reaches certain setting value, burner stops working, burner hearth
Interior rapid drop in temperature, system temperature (pressure) is also rapid therewith to be declined.After stopping working due to burner, temperature declined in burner hearth
Causing system pressure (temperature) soon, also rapid decline makes burner start and stop excessively frequent therewith, thus consumes substantial amounts of combustion gas
(unblended mixture discharge) and increase exhaust emissions.Boiler unburned gas is discharged, and is not only polluted, while increase combustion
Quick-fried danger.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of method for improving gas fired-boiler energy-conservation and stability, it can be with
Simple structure reduces the energy resource consumption of gas fired-boiler to realize, prevents the detonation of gas fired-boiler, improves the stabilization of gas fired-boiler
Property.
For the method for improving gas fired-boiler energy-conservation and stability of the present invention, above-mentioned technical problem is so to be subject to
Solve：Placement one can be heated and can store the energy saver of heat among gas fired-boiler burner hearth, and the combustion heat is lighted in combustion gas
Measure heating energy-saving device.
In the method for above-mentioned raising gas fired-boiler energy-conservation and stability, because placement can be heated and can stored in burner hearth
The energy saver of heat, in gas fired-boiler normal work engineering, when system temperature (pressure) reaches certain setting value, burner
Flame-out, temperature drop rate substantially reduces in burner hearth, can thus reduce the number of starts of burner, reach energy-saving effect；Stove
Unburned gaseous mixture, still with energy saver reactive combustion, prevents quick-fried when it from lighting a fire again after burner is flame-out in thorax
Combustion or blast, energy saver play a part of igniting and stablize burning, and steady firearm can be replaced to realize stable burning, therefore with phase
Gas fired-boiler energy-saving efficiency and stability are improved to simple structure.
As a kind of energy saver of the above method, the energy saver is porous hot runner structure.Porous hot runner structure
Have the characteristics that heat exchange area per unit volume is big, heat conduction is fast, thermal capacity is big, heat transfer rate is fast, it is ensured that the stabilization of temperature in burner hearth.
Catalytic specie is added as a kind of energy saver of the above method, in the energy saver material at 600 DEG C or so just
Catalysis burning occurs with CO, HC compound in flue gas, further improves waste heat recovery and lowers dusty gas discharge.
Brief description of the drawings
The method that described embodiment improves gas fired-boiler energy-conservation and stability for the present invention below in conjunction with the accompanying drawings
It is described further with a kind of energy saver for being heated and heat being stored.
Fig. 1 is using a kind of gas fired-boiler profilograph of the inventive method
Fig. 2 is a kind of energy saver structural representation for being heated and storing heat using the inventive method
Fig. 3 is a kind of energy saver profile using the inventive method
Embodiment
Fig. 1 shows that a kind of gas fired-boiler of gas fired-boiler 1. includes burner 2, allows combustion gas at it in a manner of profilograph
The burner hearth 3 of middle burning, flue 4, it is arranged on being heated on burner hearth 3 in hot gas boiler 1 and the energy saver of heat can be stored
5。
In gas fired-boiler specific work process, the gaseous mixture 6 of combustion gas and air passes through the igniting of burner 2, in gas-fired boiler
Burning produces heat, calory burning heating energy-saving device 5, by flue 4 and the heat in gas fired-boiler in burner hearth 3 in stove 1
Working medium water 7 carries out heat exchange and produces hot water or steam.When temperature (pressure) reaches certain setting value in gas fired-boiler 1
When, burner 2 is flame-out, and temperature declines in burner hearth, and system temperature (pressure) also declines therewith.When system reaches burner 2 again
The setting value of startup, it will be again started up through purging afterburner 2.
Because setting can be heated and store the energy saver 5 of heat on burner hearth 3, after burner is flame-out, energy saver 5
Heat discharged in burner hearth in 3, temperature will not decline too fast so as to which system pressure (temperature) also will not be rapid therewith in burner hearth
Decline makes, so burner will not start and stop it is excessively frequent, and then save substantial amounts of combustion gas (unblended mixture discharge) and
Reduce exhaust emissions, reduce boiler unburned gas discharge rate and its caused by pollution, while reduce and fire danger.
As shown in Figures 2 and 3, the energy saver 5 includes the pedestal 51 on burner hearth 3, the sheet on pedestal 51
Body 52.The lower surface of pedestal 51 is ripple struction 53.As shown in figure 3, multiple hot flow paths 54 are provided with pedestal 51.Body 52 has
There are drum type brake hollow structure 55, the hole being uniformly arranged on hollow structure 55 56 and set in middle control structure 55 multiple
Hot flow path 54 '.The hot flow path 54 and 54 ' of the energy saver 5 communicates.Porous hot runner structure has unit volume heat exchange
The features such as area is big, heat conduction is fast, thermal capacity is big, heat transfer rate is fast, it is ensured that the stabilization of temperature in burner hearth.
As a kind of preferable energy saver 5 of the above method, catalytic specie is added 600 in the energy saver material 5
DEG C or so just with flue gas CO, HC compound occur catalysis burning, further improve waste heat recovery and lower dusty gas row
Put.
It can see from above embodiment, the present invention provides a kind of gas fired-boiler that improves and saved and stability
Method, it can be arranged in burner hearth with simple structure (can be heated and store the energy saver of heat), and combustion is reduced to realize
The energy resource consumption of gas boiler, the detonation of gas fired-boiler is prevented, improve the stability of gas fired-boiler.
