Full-automatic dual purpose split burner for combustion of slurry and oil

Abstract

This invention relates to an automatic and separated burner both for water gas starch and oil. It is suitable for the medium and small size of safe heat devices. It includes the shell (3), the nozzle block, the nozzle enforcing parts, the control valve block, the air door framework, the oil pump (31), the electrical machinery (29). The nozzle block is in the shell (3), the nozzle enforcing parts and the control valve block are outside of the shell (3) and connected with the nozzle block, the air door framework is linked to the bottom of the shell (3) and connected with the chamber of the shell (3). The electrical machinery (29) is connected with the oil pump (31), and the oil pump (31) is linked to the nozzle block. This invention can realize the automatic control through the processes of firing, cease firing, charge-regulation and safe protection, and it is burned both in water gas and oil.

Description

Technical field: [0001] The invention relates to a coal water slurry burner. In particular, it relates to a fully automatic split coal-water slurry and oil dual-purpose burner. It is suitable for use in small and medium-sized safety heating equipment. Heating equipment accessories [0002] technology field. Background technique: [0003] The current situation of energy and coal-water slurry application in my country and the status of coal-water slurry combustion equipment are poor in oil and rich in coal, and the cost of fuel and gas is high. At present, coal is mainly used. However, the traditional coal-burning seriously pollutes the environment. In order to use coal scientifically and prepare deep-processed products of coal-coal-water slurry has long been included in the national eighth five-year research project. So far, it has been used in large-scale power plant boilers and kilns. It has been widely used, but the burning of coal water slurry in equipment with a larg...

Problems solved by technology

[0005] 2. The air distribution is also manually turned on and off. If the air volume is large, the fire will be blown out, and if the air volume is insufficient, black smoke will be emitted. After the fire is blown out, the oil injection pipe cannot be closed quickly. , deflagration occurs, no flameout protection device, no automatic front and rear purge

[0006] 3. The coal-water slurry part has no atomization disc and flame-stabilizing tube, so it cannot be fully atomized for combustion. It mainly falls into the furnace for combustion. The length and diameter of the flame are not controlled, and it is easy to coke in the furnace.

[0007] 4. In addition, the combustion load of the combustion device cannot be automatically adjusted according to the change of the heat load. In the case of various abnormalities and overruns in the equipment equipped with the burner, the manual valve cannot be closed quickly. Overpressure and other overrun conditions cannot be ruled out quickly, especially for heating systems with temperature requirements, which will have a serious impact and cause accidents, ranging from damage to the main equipment and auxiliary equipment, to serious casualties

[0008] 5. The nozzle body of the coal water slurry nozzle adopts an integral structure, and there is no heat-resistant and wear-resistant material embedded in the nozzle hole, resulting in poor heat resistance, wear resistance and rigidity of the nozzle; the coal water slurry directly hits the inner wall of the nozzle, and the nozzle needs to be replaced as a whole. Makes the service life of the coal water slurry nozzle short
