Description
Technical field
The utility model belongs to boiler plant technical field, is specifically related to a kind of ignition of the boiler system.
Background technology
At present, the igniting of large-sized boiler and steady combustion are all to adopt combustion fuel oil to realize traditionally, and in recent years, along with global energy shortage, price of fuel oil rises steadily, and thermal power generation fuel oil is more and more restricted.Therefore ignition of the boiler and stable combustion oil are used as a kind of important index and examine, in order to reduce the consumption of fuel oil, traditional way is to improve the fineness of coal dust, improve the preheat temperature of wind powder mixture and Secondary Air, adopt pre-combustion chamber burner, select little atomizer igniting etc., but, if to further reduce fuel oil to finally need not oil, necessary employing and traditionally diverse brand-new technique, this technique both can ensure to improve the economy of combustion process, can improve again the ecological condition of power plant.
Utility model content
The purpose of this utility model is to provide a kind of ignition of the boiler system, reduces equipment operating cost, improves operation response speed.
For realizing above object, the utility model provides a kind of ignition of the boiler system, comprise methyl alcohol coarse filter, the entrance of methyl alcohol coarse filter connects the female pipe of methanol feedstock, the outlet of methyl alcohol coarse filter connects methyl alcohol fluid reservoir successively, methyl alcohol fine filtrator, methanol pump and atomizer, atomizer is also provided with a steam access port, steam access port is connected with steam main, between methyl alcohol fluid reservoir and methyl alcohol fine filtrator, be connected with liquid stop valve A, between methanol pump and atomizer, be connected with liquid stop valve B, the steam access port of atomizer is connected with steam main by steam stop.
The beneficial effects of the utility model are: utilize methanol liquid to replace the oil ignition system of existing boiler, reduce oil mass consumption, reduce ignition of the boiler investment, and then effectively reduced the operating cost of boiler plant.The flash-point of methyl alcohol is low, can make the preheat temperature need not be too high, and igniting operation response is fast, sufficient combustion, and product is pollution-free to atmosphere; And the price of methyl alcohol is approximately the half of oil price, well below oil price.The adjusting of the flow velocity of oil in liquid stop valve A and liquid stop valve B feasible system, steam stop can be controlled the size of steam, and then adjusts atomizing effect, makes the use of native system more flexible.Therefore, this ignition of the boiler system has not only effectively reduced investment and the operating cost of equipment, and igniting operation response is fast, and combustion products is pollution-free to atmosphere, and system atomizing effect is adjustable, belongs to energy saving and environment friendly operational system.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model;
In figure: 1. methyl alcohol fluid reservoir; 2. methyl alcohol fine filtrator; 3. methanol pump; 4 methyl alcohol coarse filters; 5. atomizer; 6. liquid stop valve A; 7. liquid stop valve B; 8. steam stop.
Detailed description of the invention
For making object, technical scheme and the advantage of the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
embodiment 1:
With reference to Fig. 1, the utility model provides a kind of ignition of the boiler system, comprise methyl alcohol coarse filter 4, the entrance of methyl alcohol coarse filter 4 connects the female pipe of methanol feedstock, outlet connects methyl alcohol fluid reservoir 1 successively, methyl alcohol fine filtrator 2, methanol pump 3 and atomizer 5, atomizer 5 is also provided with a steam access port, steam access port is connected with steam main, between methyl alcohol fluid reservoir 1 and methyl alcohol fine filtrator 2, be connected with liquid stop valve A6, between methanol pump 3 and atomizer 5, be connected with liquid stop valve B7, atomizer 5 steam access ports are connected with steam main by steam stop 8.
Methyl alcohol coarse filter 4 is connected by pipeline with methyl alcohol fluid reservoir 1, stores methanol liquid, so that ignition of the boiler is used; Methanol liquid is under the power of methanol pump 3, enter methyl alcohol fine filtrator 2 by liquid stop valve A6, be transported to atomizer 5 imports by pipeline, steam from boiler is sent into atomizer 5 imports by steam stop 8, utilize from the steam of boiler the methyl alcohol atomization that heats up, reach methyl alcohol flash temperature, then through and air mixing send into boiler and light a fire.
The utility model utilizes methanol liquid to replace the oil ignition system of existing boiler, reduces oil mass consumption, reduces ignition of the boiler investment, and then has effectively reduced the operating cost of boiler plant.The flash-point of methyl alcohol is low, can make the preheat temperature need not be too high, and igniting operation response is fast, sufficient combustion, and product is pollution-free to atmosphere; And the price of methyl alcohol is approximately the half of oil price, well below oil price.The adjusting of the flow velocity of oil in liquid stop valve A and liquid stop valve B feasible system, steam stop can be controlled the size of steam, and then adjusts atomizing effect, makes the use of native system more flexible.Therefore, this ignition of the boiler system has not only effectively reduced investment and the operating cost of equipment, and igniting operation response is fast, and combustion products is pollution-free to atmosphere, and system atomizing effect is adjustable, belongs to energy saving and environment friendly operational system.
