Estimating the term…
An ammonia preheating flow-controllable low-nitrogen ammonia-coal co-firing burner is provided according to the present application, including a primary air duct, an inner secondary air duct, and an outer secondary air duct. The gas injector in the primary air duct is used to mix gas uniformly into primary air-coal powder flow. The gas injectors in the inner secondary air duct and the outer secondary air duct are arranged in a staggered configuration, with nozzles in both the gas injectors in the inner secondary air duct and the outer secondary air duct curving toward a center of a burner outlet, directing gas into flame core. By arranging different types of the gas injectors in the primary air duct, the inner secondary air duct, and the outer secondary air duct, and optimizing their positions, promoting a more uniform combustion process and improving overall combustion efficiency and stability.
An ammonia preheating flow-controllable low-nitrogen ammonia-coal co-firing burner, comprising a primary air duct, an inner secondary air duct, and an outer secondary air duct arranged sequentially from inside to outside, wherein the primary air duct, the inner secondary air duct, and the outer secondary air duct are internally provided with gas injectors, respectively, the gas injector in the primary air duct is used to mix gas uniformly into primary air-coal powder flow, the gas injectors in the inner secondary air duct and the outer secondary air duct are arranged in a staggered configuration, with nozzles in both the gas injectors in the inner secondary air duct and the outer secondary air duct curving toward a center of a burner outlet, directing gas into flame core.
