Abstract
A kind of multiple-pipe direct spray high-voltage electric impulse heating burner, it is characterized in that comprising coal pipe (1), disperser (2), earthenware (3) and the mouth that dusts (4), described coal pipe (1) connects earthenware (3) by disperser (2), and earthenware (3) end is provided with the mouth that dusts (4).Multiple-pipe direct spray high-voltage electric impulse heating burner of the present invention is the burner of design innovation mainly for China's existing operation small scall coal-fired boiler, use the boiler after the multiple-pipe direct spray high-voltage electric impulse heating burner technological transformation of invention, can save energy more than 30%, improve boiler thermal output about 25%, there is automatic control, simple to operate, boiler room environmental friendliness, the effect of flue dust clean emission.
Description
The present invention relates to pulverized-coal fired boiler technical field, especially a kind of multiple-pipe direct spray high-voltage electric impulse heating burner.
At present, the coal-burning boiler of China's substantial amounts, face technical barrier technological transformation is during upgrading, under worst hot case, very easily there is high temperature deformation in combustion tube, has a strong impact on use.
Main purpose of the present invention is to provide a kind of multiple-pipe direct spray high-voltage electric impulse heating burner preventing high temperature deformation energy-conserving and environment-protective.
Technical scheme of the present invention is:
A kind of multiple-pipe direct spray high-voltage electric impulse heating burner, coal pipe, disperser, earthenware and the mouth that dusts, described coal pipe connects earthenware by disperser, and earthenware end is provided with the mouth that dusts.
The described mouthful opening that dusts is horn-like.
High-tension current heater coil is provided with in described earthenware.
The invention has the beneficial effects as follows:
Multiple-pipe direct spray high-voltage electric impulse heating burner of the present invention is for the coal-burning boiler of China's substantial amounts, technology upgrading house of correction problems faced, by Burner Technology of the present invention, only need take coal bunker installs burner of the present invention and coal powder storage and supply system additional, just economize energy can be reached, effect of emissions reduction, lifting economic benefit.
Multiple-pipe direct spray high-voltage electric impulse heating burner of the present invention is the burner of design innovation mainly for China's existing operation small scall coal-fired boiler, use the boiler after multiple-pipe direct spray high-voltage electric impulse heating burner technological transformation of the present invention, can save energy more than 30%, improve boiler thermal output about 25%, there is automatic control, simple to operate, boiler room environmental friendliness, the effect of flue dust clean emission.
Fig. 1 is structural representation of the present invention.
In figure: 1 be coal pipe, 2 be disperser, 3 for earthenware, 4 be the mouth that dusts, 5 for high-tension current heater coil.
Below in conjunction with accompanying drawing, the invention will be further described:
As Fig. 1, a kind of multiple-pipe direct spray high-voltage electric impulse heating burner, comprise coal pipe 1, disperser 2, earthenware 3 and the mouth 4 that dusts, described coal pipe 1 connects earthenware 3 by disperser 2, and earthenware 3 end is provided with the mouth 4 that dusts.
Mouth 4 opening that dusts is horn-like.
High-tension current heater coil 5 is provided with in earthenware 3.
It is special that multiple-pipe direct spray high-voltage electric impulse heating burner of the present invention is applicable to SZS pulverized-coal fired boiler, multiple-pipe direct spray high-voltage electric impulse heating burner of the present invention is used evenly to send coal dust to burner hearth suspension combustion, with high-temperature ceramic internal high-voltage current flow heats coil, by wind powder in ceramic flue transient heating earthenware, and enter burner hearth homogenous combustion, be applicable to small-sized SZS6-16-25pa special coal powder burner.
Embodiment recited above is only be described the preferred embodiment of the present invention; not the spirit and scope of the present invention are limited; do not departing under design concept prerequisite of the present invention; the various modification that in this area, common engineers and technicians make technical scheme of the present invention and improvement; all should fall into protection scope of the present invention, the technology contents of request protection of the present invention is all recorded in detail in the claims.
