Abstract
The invention discloses a firing stabilizer which is used for a coal-fired boiler burner and comprises flow guide blocks, arc-shaped stable combustion bodies and a flow guide sphere, wherein the flow guide blocks are mounted at the primary air gradual flaring of the burner; openings are formed in two sides of the arc-shaped stable combustion bodies; the opening facing the coal inlet direction is smaller, and the opening on the other side are larger; the flow guide sphere is arranged in the arc-shaped stable combustion bodies. The firing stabilizer, disclosed by the invention, effectively enables pulverized coal air flow to return, can form a high-concentration pulverized area at the rear of the firing stabilizer, and improves the combustion efficiency of pulverized coal.
Description
Technical field
The present invention relates to a kind of stabilizer, particularly a kind of stabilizer be applicable in coal-fired boiler combustion device.
Background technology
In coal-burning boiler, the Thorough combustion of coal dust, to saving the energy, ensureing that the normal operation of boiler and environmental protection all have important meaning, especially some low volatile meager coal and anthracite, not easily Thorough combustion, needs to solve the problem of igniting and surely firing.
Usually in coal-fired boiler combustion device, adopt the modes such as gas cyclone, reamer structure, Pulverized Coal Concentration to strengthen the burning of coal dust, adopt the mode of spray combustion oil to assist simultaneously.And when combustor mechanism is set, smooth combustion apparatus is generally used for the eddy flow increasing breeze airflow, make breeze airflow in the region forming high concentration, high temperature and suitable oxygen concentration after stabilizer, therefore, vital effect is played in the abundant conflagration of stabilizer to coal dust rational in infrastructure, the combustion rate of coal dust can be improved, reduce the use amount of auxiliary combustion oil, ensure the Effec-tive Function of coal-burning boiler.
Summary of the invention
The object of this invention is to provide a kind of stabilizer, be mainly used in coal-fired boiler combustion device, this stabilizer structure is simple but have steady fuel efficiency fruit preferably.
For achieving the above object, the stabilizer structure of the present invention's design is as follows:
Comprise baffle, arc combustion stabilizing body and water conservancy diversion spheroid, baffle is installed on burner First air flaring mouth place, arc combustion stabilizing body both sides are opening, in the face of the opening coming coal direction is little, the opening of opposite side is large, it is inner that water conservancy diversion spheroid is positioned at arc stabilizer, and the edge that the upright position at water conservancy diversion spheroid edge is positioned at arc combustion stabilizing body is inner.
More preferably, baffle, arc stabilizer and water conservancy diversion spherome surface are evenly equipped with the ripple parallel with the coal dust direction of motion.
Advantage of the present invention and beneficial effect are:
1) water conservancy diversion efficiently can be carried out to breeze airflow, promote that breeze airflow forms backflow at stabilizer rear, reach the object improving coal powder density;
2) stabilizer entirety adopts comparatively open structure, is more conducive to oxygen and fully contacts with coal dust, and improve the temperature homogeneity in whole burner.
Accompanying drawing explanation
Figure is schematic diagram of the present invention;
Fig. 1 is the structure chart of stabilizer;
Wherein: 1, burner housing; 2, baffle; 3, arc combustion stabilizing body; 4 water conservancy diversion spheroids.
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
The technical scheme that the present invention specifically implements is:
A kind of stabilizer, for in coal-fired boiler combustion device, comprise baffle 2, arc combustion stabilizing body 3 and water conservancy diversion spheroid 4, baffle 2 is installed on burner housing 1, is positioned at First air flaring mouth place, and arc combustion stabilizing body 3 both sides are opening, in the face of the opening coming coal direction is little, the opening of opposite side is large, and it is inner that water conservancy diversion spheroid 4 is positioned at arc stabilizer 3, and the edge that the upright position at water conservancy diversion spheroid 4 edge is positioned at arc combustion stabilizing body 3 is inner; Baffle 2, arc stabilizer 3 and water conservancy diversion spheroid 4 surface are evenly equipped with the ripple parallel with the coal dust direction of motion.
When breeze airflow is from left to right through stabilizer, two parts will be divided into by stabilizer, centre is dense coal region, straight line enters the inside of arc stabilizer 3, periphery is light coal region, enter stabilizer rear by the guiding being arranged on baffle 2 on burner housing and arc stabilizer 3, form backflow; And middle dense coal region is in the process moved on, can be formed by water conservancy diversion spheroid 4 and stream, form backflow at the rear of water conservancy diversion spheroid 4, the backflow then formed with light coal is met simultaneously, form a high-concentration coal region at the rear of stabilizer, improve efficiency of combustion.The structure of whole stabilizer is camber line, decreases the stop to breeze airflow, makes breeze airflow can promptly arrive stabilizer rear, meanwhile, because each body structure surface has the ripple parallel with the coal dust direction of motion, can play better guiding function.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
