Abstract
The utility model discloses a high-efficient coal combustor, which comprises a combustion chamber. A flame retardant coating is arranged on the inner side of a casing of the combustion chamber, the combustion chamber is equipped with a coal dust and primary air mixing inlet, and the coal dust and primary air mixing inlet is a cyclone structure. Coal dust suspends and burns in the combustion chamber through a cyclone form with sufficient mixed combustion, the final burning temperature is enabled to achieve the preset high temperature, wherein the highest temperature achieves over 1500 DEG C and temperature rise speed runs up to 60 DEG C/min. The high-efficient coal combustor equipped with a secondary air inlet passage can accelerate cyclone suspension and supplemental burning of the coal dust in the combustion chamber, and enables flame and unburned coal dust to spray into heating devices such as a boiler and the like to burn off, thereby forming secondary suspended burning. Furnace slag is in fused liquid state. The utility model realizes 80% liquid slag discharge through smoke gas cyclone power with more than 98% coal burn-off rate, thereby realizing the purpose of basically burning off coal and achieving the purpose of saving coal, saving energy and reducing consumption. The utility model is compact in structure, small in volume and light in weight.

Therefore, need a kind of coal-fired combusting device, can improve coal-fired burn-off rate and efficiency of combustion greatly, make coal-fired fully mixed combustion in the burner, final ignition temperature reaches predetermined high temperature, saves fire coal and energy saving purposes thereby reach.
The utility model content
In view of this, the utility model provides a kind of efficient fuel coal burner, can improve coal-fired burn-off rate and efficiency of combustion greatly, make coal-fired fully mixed combustion in the burner, final ignition temperature reaches predetermined high temperature, realize slag tap, save fire coal and energy saving purposes thereby reach.
Efficient fuel coal burner of the present utility model comprises the combustion chamber, and described combustor outer casing inboard is provided with flame retardant coating, and described combustion chamber is provided with a coal dust and a wind mixing import, and a described coal dust and a wind mixing import are hydrocyclone structure.
Further, also comprise at least one secondary air passage, described secondary air passage passes combustor outer casing and flame retardant coating tangentially enters the combustion chamber, and approach axis is identical with the eddy flow direction of hydrocyclone structure;
Further, described combustor outer casing arranged outside cooling water jecket, the secondary air passage passes water leg;
Further, described combustion chamber is the cylindrical structural that conical head is set, and described hydrocyclone structure is arranged at the conical head center along axis, and the point of observation fire hole also is set on the conical head;
Further, described secondary air passage is provided with volume damper;
Further, described volume damper comprises adjusting handle, valve plate and screw mandrel, described valve plate is arranged in the secondary air passage, and adjusting handle is fixedly installed on the secondary air channel outer wall, and adjusting handle opens or closes the secondary air passage by the screw mandrel drive valve plate;
Further, described secondary air passage is uniformly distributed along the circumference two groups, and every group is two and is set up in parallel vertically.
The beneficial effects of the utility model: efficient fuel coal burner of the present utility model, adopt the coal dust and a wind mixing import of hydrocyclone structure, coal dust and combustion-supporting gas mix before entering the combustion chamber, and in the combustion chamber, carry out suspension combustion by cyclone mode, mixed combustion is abundant, final ignition temperature reaches predetermined high temperature, maximum temperature can reach more than 1500 degrees centigrade, programming rate is up to 60 degrees centigrade/min, slag is fused solution, and realizes 80% slag tap by flue gas eddy flow power, and coal-fired burn-off rate reaches more than 98%, reach the purpose of coal-fired basic after-flame, realize saving coal-fired and energy-saving and cost-reducing; The utility model compact conformation, volume are little, in light weight.
