Description

Technical Field

[0001] The present invention relates to the technical field of generator burners, and in particular to an energy-saving boiler burner for a generator. Background Art

[0002] Energy-saving generators refer to power generation equipment that significantly reduces energy consumption and carbon emissions through optimized design, the use of high-efficiency technology, or the use of renewable energy. The boiler burner in an energy-saving generator is a core component, and its technological development directly affects the thermal efficiency, emission level, and operating cost of the power generation system. Traditional burners have the following problems: the combustion-supporting gas is directly introduced into the burning furnace at room temperature, which reduces the combustion efficiency; the use of a single solid fuel results in low combustion efficiency; when gas and solid fuel are mixed, the volume of the solid fuel is too large, resulting in insufficient mixing of the fuel and air, resulting in incomplete combustion of the solid fuel and large heat loss; the boiler burners for generators in the existing technology do not make effective use of waste heat during use, resulting in low combustion efficiency and high energy consumption. Summary of the Invention

[0003] In response to the above technical problems, the present invention adopts the following technical solutions: an energy-saving boiler burner for a generator, comprising a combustion mechanism for burning coal, the combustion mechanism comprising an outer cylinder, the combustion mechanism being provided with a processing mechanism for crushing the coal and a recovery mechanism for recovering combustion residues, the processing mechanism comprising an inlet shell; The combustion mechanism includes an air intake plate fixedly mounted on the outer tube, one end of a plurality of preheating air pipes fixedly mounted on the air intake plate, a combustion tube fixedly mounted inside the outer tube, the preheating air pipes adhere to the outer surface of the combustion tube, the other end of the preheating air pipes is connected to the inside of the combustion tube, and a conveying shaft is rotatably mounted inside the shell.

[0005] Furthermore, a filter element turntable is rotatably installed on the air intake disc, and multiple filter elements are arranged on the filter element turntable. A lifting frame is slidably installed on the air intake pipe, and a tension spring is arranged between the lifting frame and the air intake disc. An air inlet is provided on the air intake disc, and the air inlet is located below the air intake pipe.

[0006] Furthermore, a large conveying shaft is fixedly installed on the conveying shaft, the large conveying shaft contacts the inner wall of the combustion tube, a slag shell is fixedly installed on the outer tube, a slag tube is fixedly installed in the slag shell, a slag retaining ring is fixedly installed on the slag tube, the large conveying shaft contacts the inner wall of the slag tube, and a plurality of holes are provided on the slag tube.

[0007] The crushed coal is transported to the combustion tube through the conveyor shaft, and the gas is fed into the combustion tube through the gas pipe. The igniter in the combustion tube ignites the coal and the gas is burned together. The air intake motor drives the air intake fan to rotate, and the outside air is drawn into the intake pipe. The air is filtered out of dust and other impurities through the filter element to prevent incomplete combustion of the coal. The filtered air enters the air intake plate and then enters the preheating air pipe. The temperature generated by the combustion in the combustion tube preheats the air in the preheating air pipe. The preheated air enters the combustion tube for auxiliary combustion. Preheating the air can improve the combustion efficiency of the coal to save energy. The flame generated by the combustion is ejected from the slag retaining ring. The conveying shaft drives the large conveying shaft to rotate, and the large conveying shaft drives the coal to move in the combustion tube, pushing the residue produced by combustion to the slag discharge tube. The slag blocking ring blocks the residue, and finally the residue falls into the recovery seat through the hole of the slag discharge tube.

[0008] After the filter element has been used for a period of time, the lifting frame can be lifted, the tension spring is stretched, the filter element turntable is rotated, and the unused filter element is rotated to the bottom of the intake pipe to replace the filter element. Then the tension spring rebounds and the lifting frame closes the intake pipe and the intake disc again.

The guide column slides along the inclined slot, thereby driving the crushing plate to swing back and forth, putting the coal into the crushing bucket. The crushing plate swings back and forth to crush the coal through the crushing teeth. The crushed coal falls onto the conveying shaft and is transported to the combustion barrel through the conveying shaft. Crushing the coal before burning can improve combustion efficiency.

[0013] Furthermore, a slag outlet is provided in the recovery seat.

[0014] The motor rotates through the gear transmission to drive the bottom shaft and the bottom conveying shaft to rotate. The bottom shaft drives the lower shaft to rotate through the gear transmission, thereby driving the conveying shaft to rotate. After the combustion residue falls into the recovery seat, it is located on the bottom conveying shaft and is transported to the slag outlet through the bottom conveying shaft for discharge and collection.

The temperature generated by the combustion in the combustion barrel 110 preheats the air in the preheating air pipe 111. The preheated air enters the combustion barrel 110 for auxiliary combustion. Preheating the air can improve the combustion efficiency of the coal and save energy. The flame generated by the combustion is ejected from the slag retaining ring 117, and the conveying shaft 114 drives the large conveying shaft 115 to rotate.
