The invention discloses a nozzle part of a hot blast stove for burning waste gas. The nozzle part comprises a nozzle shell body, a fuel inlet, a fuel core pipe, a nozzle brick and an igniter. The nozzle part is provided with an air core pipe and a second air pipe body; the air core pipe penetrates through the second air pipe body and the nozzle shell body; the end part, which is close to the nozzle brick, of the air core pipe is provided with a nozzle baffle; the nozzle brick is provided with a main combustion cavity and more than six annular combustion cavities; the annular combustion cavities surround the main combustion cavity; the nozzle shell body is internally provided with air through pipes the quantity of which is the same as that of the annular combustion cavities; one end of each air through pipe penetrates into the second air pipe body, the other end of each air through pipe penetrates into the annular combustion cavity of the nozzle brick; and each annular combustion cavity of the nozzle brick is internally provided with a support piece through which waste gas passes. In the nozzle part of the hot blast stove for burning the waste gas, the structure is adopted, therebyachieving complete combustion, reducing emission of pollution sources and saving fuel.
Description
technical field [0001] The invention relates to a hot blast stove, in particular to a burner part of a waste gas incineration hot blast stove. Background technique [0002] In the fields of metallurgy and chemical industry, hot blast stoves are needed. For example, in the iron and steel smelting process, waste gas incineration hot blast stoves are arranged between the reduction furnace and the oxidation furnace. The purpose is to incinerate the tail gas of the reduction furnace. Using coke oven fuel, the hot flue gas produced by the combustion of the above two gases is sent to the oxidation furnace, and the temperature is usually between 900 and 1300 degrees, which is used as the heat source of the oxidation furnace. The existing waste gas incineration hot blast stove includes a furnace body, a burner part, an explosion-proof part, a release pipe and an ash unloading part. The burner part includes a burner shell body, a fuel inlet, a fuel core tube, a burner brick and an ign...
