Abstract
The invention comprises a burner body and a primary flue pipe jointed firmly with the burner body. In the primary flue pipe is welded a separation plate. At the front end located on the inner wall of the burner body there is a guide block with a lug. On the inner wall of the burner front part are disposed several smooth burning pieces. On the side wall of the burner body located between the guide block and the smooth burning pieces are firm-jointed oil gun tubes having a combustion tube each. In each of combustion tubes is inserted a small oil gun.
Description
Technical field
The present invention relates to the igniter of thermal power plant pulverized-coal fired boiler, be particularly useful for the ignition system of the DC burner of pulverized-coal fired boiler coner firing.
Background technology
Existing thermal power plant large coal powder boiler all needs to use a large amount of diesel oil in opening furnace igniting, furnace shutting down process, make the coal dust firing that spurts in the stove, in addition, it is combustion-supporting more will to drop into a large amount of diesel oil when boiler at low load moves or during burning inferior coal, to reach the purpose of smooth combustion.Therefore, the original firing technique amount of fuel of thermal power plant very big (power industry annual oil consumption cross 1,200 ten thousand tons) and mostly be light diesel fuel is a huge spending of production cost.
Summary of the invention
In order to solve the serious problems of existing thermal power plant pulverized coal boiler ignition fuel oil waste, the invention provides a kind of brand-new igniter, this device is according to brand-new Theory of Combustion---and stepless combustion technology develops, and only need drop into the needs that seldom oil mass just can satisfy thermal power plant 50-1000Mn capacity large-sized boiler safely and reliably during igniting.This is the technical merit that does not reach as yet both at home and abroad at present, and simple and reliable for structure.
The technical scheme that adopts is:
Coal powder boiler straight-flow burner igniting device, comprise burner body, an airduct, burner body is fixedlyed connected with an airduct, its design feature is to be welded with one to separate dividing plate in an airduct, be positioned at lobed guide pad on the inwall of burner body at the front end that separates dividing plate, be equipped with a plurality of steady combustion lobes on the inwall of burner body front portion, leading section in the burner body is a square tube shape, rear portion in the burner body is a cylindrical shape, between guide pad and steady combustion lobe, be installed with two symmetrically on the sidewall of burner body, and sweptback oil barrel, be installed with a combustion barrel respectively in two oil barrels, all be inserted with a small oil gun in the combustion barrel.
Above-mentioned small oil gun inserts in the combustion barrel with 45.
Above-mentioned guide pad is a crescent.
Above-mentioned burner body is a cylindrical shape, and its leading section is a square tube shape.
Steady combustion lobe on the above-mentioned burner body inwall is three, and three steady combustion lobes evenly are 120 ° at interval.
The present invention compared with prior art, available indivisible fuel oil is finished the start and stop and the low-load combustion-stabilizing of boiler, has advantages such as simple in structure, easy to operate, stable, that oil-saving effect is obvious simultaneously, has the practical prospect of wide industrial.
