Abstract
The utility model relates to a coal power combustion apparatus, comprising a blower 3, a burner 4 and a kiln head cover 5, wherein, the inlet of the blower 3 is provided with a temperature regulating valve 1 and a separating device 2; a dust outlet in the separating device 2 is connected with the kiln head cover 5; the gas outlet of the separating device 2 is connected with the inlet of the blower 3; the regulating valve 1 is connected in series between the kiln head cover 5 and the inlet of the separating device 2; coal powder entering the burner 4 is blown into a kiln by the blower 3 to burn; hot air drawn by the blower 3 from the kiln head cover is used as the primary air for burning coal. The utility model can reduce the heat consumption of burning grog and cause the fuel to be ignited and burnt easily, and the utility model is especially suitable for burning systems using low active fuel and inferior fuel.
Description
The utility model relates to a kind of coal powder burner.
In traditional cement rotary kiln pulverized coal combustion system, the coal dust that comes out from Pulverized Coal Bin is pumped into the burner tube through one, uses a typhoon machine air blast in addition, sends into combustion air, and coal dust is sent into the kiln internal combustion.This blower fan suction natural environment air is blown in the kiln by a certain amount of.Because it is lower from the air themperature of natural environment suction, to absorb heat rising temperature after entering in the kiln, increased the required hear rate of clinker burning on the one hand, the starting stage that makes fuel go into kiln on the other hand is under the environmental condition of lower temperature, for the lower fuel of activity, be difficult for fire burns.In order to improve burning condition and to reduce grog and burn till hear rate, the method of present more use is the coal burner structure to be received make, the cold blast rate of sending in the kiln by blower fan is reduced to some extent, after making cold wind go into kiln simultaneously, carrying coal dust secretly mixes with hot-air in the kiln quickly, thereby the reduction hear rate is improved the coal dust firing condition.
The purpose of this utility model changes original cement kiln coal powder burner at the defective of above-mentioned existence, thereby makes the coal dust firing process conditions better, and it is lower that grog burns till hear rate.
Technical solution of the present utility model:
Comprise blower fan 3, burner 4, kiln hood cover 5 is provided with temperature control valve (TCV) 1 and separator 2 in the import department of blower fan 3, and the dust outlet in the separator 2 connects kiln hood cover 5, the give a dinner for a visitor from afar import of machine 3 of the gas vent of separator 2, control valve 1 is to be serially connected between the import of kiln hood cover 5 and separator 2.Coal dust firing technology, coal dust enter burner 4, send into the kiln internal combustion by blower fan 3 air blast, and blower fan 3 is taken out with the wind of hot blast as coal combustion from the kiln hood cover.
Accompanying drawing is an embodiment schematic diagram of the present utility model.Among the figure 1 is control valve, the 2nd, and separator, the 3rd, blower fan, the 4th, burner, the 5th, the kiln hood cover all belongs to prior art.
Characteristics of the present utility model are to adopt high temperature resistant a, high pressure, low air quantity blower fan, aspirate the kiln head heat air as delivering coal combustion air from the kiln hood cover, blower fan separates dust from the hot blast of kiln hood cover suction through separator, again by a valve regulated hot air temperature, make it reach reasonable request, hot-air after separating dust and levelling temperature is sent into coal dust in the kiln, burn, the utility model can make grog burn till the hear rate reduction, fuel easier fire burns, be specially adapted to firing system with low activity or inferior fuel.
