Low-nitrogen combustor for biological natural gas

Abstract

The invention relates to the technical field of combustors, in particular to a low-nitrogen combustor for biological natural gas. The low-nitrogen combustor is characterized in that an air supply mainpipe is provided with a primary air pipe and a secondary air pipe in a communicating mode, the primary air pipe is connected with a primary air adjusting valve, the secondary air pipe is connected with a secondary air adjusting valve, the other end of the primary air pipe communicates with a primary air chamber, a plurality of primary air branch pipes are connected to the primary air chamber in apenetrating mode, the other end of the primary air branch pipe located at the circle center position is connected with a middle concentric jet flow air pipe in a penetrating mode, the other ends of aplurality of primary air branch pipes which are annularly distributed by taking the primary air branch pipe on the circle center as the circle center are connected with annular jet air pipes in a penetrating manner, and the primary air branch pipes are arranged in a gas chamber. The combustor effectively solves the problems that in the prior art, a combustor is poor in combustion effect, complexin structure, high in manufacturing cost, poor in fuel and air mixing effect and the like.

Description

technical field [0001] The invention relates to the technical field of burners, in particular to a low-nitrogen burner for bio-natural gas. Background technique [0002] Energy is the basic element of human survival and development, and it is also the engine and fundamental driving force of social and economic development. With the resource depletion and environmental problems caused by the resource development and application of fossil energy are becoming more and more serious, especially our country is facing the dual pressure of economic growth and environmental protection, the supply capacity of clean fuel is related to the sustainability of the national economy Development, agricultural residues (straw, rice husk, peanut shells, etc.) and forestry residues (logging residues, wood processing waste, construction waste, etc.) Develop biomass waste gasification combustion equipment to try to solve the problems of energy shortage and environmental pollution.
