Abstract

The invention relates to a post-premixed wall type laminar flow water-cooled ultra-low nitrogen combustion device and a control method thereof, which are characterized by comprising an adaptive jet mixer (1), a laminar flow flame arrester combustion head (2), and a flame cooling device (3), ignition and flame sensing device (4); the lower end of the adaptive jet mixer (1) is fixedly connected to the upper end of the laminar flow flame retardant combustion head (2), and the lower end of the laminar flow flame retardant combustion head (2) is connected to the flame cooling device (3) Connection; ignition and flame sensing device (4) is located below the flame cooling device (3). The adaptive jet mixer in the present invention can realize the mixing uniformity and mixing ratio stability of natural gas and combustion-supporting air at a 1:5 adjustment ratio, realize laminar flow combustion technology coupled with water-cooled combustion technology, and realize laminar water-cooled ultra-low nitrogen combustion.

Description

technical field [0001] The invention relates to the technical field of clean energy, in particular to a post-premixed wall-type laminar water-cooled ultra-low nitrogen combustion device to realize the efficient combustion of natural gas energy and ultra-low nitrogen emission. Background technique [0002] With the development of my country's economy and society, the original energy development model can no longer meet the needs of social development, and the energy utilization form of energy saving and environmental protection is the current development direction. The national long-term energy development strategy plans to reduce the proportion of coal in primary energy consumption to below 50% by 2030. Data show that from 2006 to 2015, the proportion of global coal and oil consumption decreased by about 2.3 percentage points, while the proportion of natural gas increased by about 1 percentage point. In 2015, my country's natural gas consumption was as high as 193.1 billion...
