Heat storage premixed biomass gas combustor and using method thereof

Abstract

The invention discloses a heat storage premixed biomass gas combustor and a using method thereof. The combustor comprises a porous medium heat storage premixing pipeline, an inner combustion-supporting air pipeline, an outer gas pipeline, an outer combustion-supporting air pipeline, a first sleeve, an inner combustion-supporting air rotational flow adjusting pull rod, a second sleeve, an outer gasrotational flow adjusting pull rod, a plurality of inner combustion-supporting air axial rotational flow blades and a plurality of outer gas axial rotational flow blades. The porous medium heat storage premixing pipeline, the inner combustion-supporting air pipeline, the outer gas pipeline and the outer combustion-supporting air pipeline are sequentially distributed from inside to outside, an outlet of the porous medium heat storage premixing pipeline is filled with a ceramic foam type porous medium, and an inlet of the porous medium heat storage premixing pipeline coaxially communicates witha central gas pipeline and a central combustion-supporting air pipeline. According to the combustor and the using method thereof, the purpose of efficient and low-pollution combustion of biomass gascan be achieved.

Description

technical field [0001] The invention belongs to the technical field of combustion equipment, and relates to a thermal storage premixed biomass gas burner and a use method thereof. Background technique [0002] Energy is a basic industry related to the national economy and the people's livelihood. As my country's economic development enters the new normal, the growth rate of energy consumption is gradually slowing down, and the problems of energy utilization efficiency and development quality are becoming more and more prominent. The energy structure is diversified and the construction of clean, low-carbon, safe and efficient modern energy System is a major historical mission of energy development and reform. Therefore, saving energy and expanding the scope of energy utilization are extremely important to my country's economic construction. The application of low-calorific-value fuels such as biomass gas can improve the efficiency of comprehensive energy utilization and at th...
