Low-enthalpy ternary gas co-combustor

Abstract

The invention discloses a low-enthalpy ternary gas co-combustor. The low-enthalpy ternary gas co-combustor comprises a housing and a plurality of ventilating channels, wherein an ignition fuel gas inlet, a low-enthalpy fuel gas inlet and a co-combustion fuel gas inlet are formed in the housing; the direction of the ignition fuel gas inlet is perpendicular to the direction of the low-enthalpy fuel gas inlet and the co-combustion fuel gas inlet; the ventilating channels are arranged in the housing in a mutually parallel mode, and separately communicate with the ignition fuel gas inlet, the low-enthalpy fuel gas inlet and the co-combustion fuel gas inlet on different positions. According to the low-enthalpy ternary gas co-combustor disclosed by the invention, low-enthalpy artificial coal gas and combustion-supporting high-enthalpy coal gas are tightly integrated in process, and are separately introduced into a common co-combustion barrel to form non-homogeneous co-combustion of low-enthalpy gas and high-enthalpy gas, so that defects such as hard-to-control combustion, explosiveness, tempering and flame-lifting are overcome.

Description

technical field [0001] The invention belongs to the field of environmental protection equipment and relates to a low-enthalpy ternary gas mixed burner. Background technique [0002] Today, the "three wastes" (solid waste, liquid waste, and gas waste) are treated by thermal decomposition and incineration process. During the implementation of this process, the artificial gas formed by pyrolysis and gasification is a low-enthalpy combustible gas. Thermal decomposition is the use of thermal energy to break the chemical bonds of compounds, and transform from large molecular weight organic matter into small molecular weight carbon monoxide (CO), hydrogen (H 2 ), methane (CH 4 ) and other combustible gases and slag. CO, H in combustible gas 2 、CH 4 It is a low-enthalpy gas that is a greenhouse gas. In the process of ignition and accompanying combustion, it may be due to the non-uniform mixing of the gas, the temperature of the gasification agent entering it, and the non-linear...

CO, H in combustible gas 2 、CH 4 It is a low-enthalpy gas that is a greenhouse gas. In the process of ignition and accompanying combustion, it may be due to the non-uniform mixing of the gas, the temperature of the gasification agent entering it, and the non-linearity of the gas-mixing safety ratio. Due to the conditions, the burning at the ignition point is easy to be blocked and explosive
