Intelligent natural gas and pulverized coal dual-purpose burner

Abstract

The invention discloses an intelligent natural gas and pulverized coal dual-purpose combustor. A combustor body of the intelligent natural gas and pulverized coal dual-purpose combustor is composed of a pulverized coal gun, a natural gas injection device, a ventilating duct and an air volume adjusting mechanism. The pulverized coal gun is located at the center position of the pulverized coal combustor body. A pulverized coal gun body front-back adjusting mechanism used for adjusting the distance between a pulverized coal spray opening and a whirlwind leaf at the rear end of a primary air duct and a bluff body adjusting mechanism are arranged on the pulverized coal gun. The natural gas injection device is located on the outer side of the pulverized coal spray gun and is concentric with the pulverized coal spray gun. A guide barrel of the pulverized coal spray gun forms an inner barrel of the natural gas injection device. The end of the natural gas injection device is provided with a gas injection mechanism. The pulverized coal gun and the natural gas injection device are arranged in the same combustor, and both natural gas and pulverized coal can be independently and stably combusted and can be immediately switched in the actual running process, so that the phenomenon that a boiler shuts down when one kind of fuel supply is insufficient or combustion conveying equipment breaks down is avoided, and continuity, stability and reliability of the intelligent natural gas and pulverized coal dual-purpose combustor are achieved.

Description

technical field [0001] The invention relates to a combustion device, in particular to an intelligent natural gas and pulverized coal dual-purpose burner suitable for high-efficiency, energy-saving, green and environment-friendly pulverized coal boiler supporting equipment. Background technique [0002] With the development of economy and society, human's demand for energy is increasing year by year. Before fusion energy, solar energy, geothermal energy and other new energy utilization technologies mature, fossil fuels such as coal, oil, and natural gas are still the main energy sources for human survival. Therefore, the production and development of combustion equipment for coal (powder), fuel oil, and gas (natural gas, blast furnace gas, coke oven gas, producer gas, etc.) is still a hot industry. For my country, due to the high prices of natural gas and oil, coal accounts for more than 70% of my country's total energy consumption, and the energy structure dominated by coal ...
