Abstract

The invention discloses a cyclone airflow field combustion chamber. The cyclone airflow field combustion chamber comprises a shell body, the position, close to the top, of the interior of the shell body is provided with feeding inlets, the position, close to the bottom, of the interior of the shell body is provided with air inlets, the inner wall of the shell body is fixedly connected with an insulating lining outer wall, and the bottom of the shell body is provided with a slag pond. According to the cyclone airflow field combustion chamber, through the feeding inlets, powdered fuel enters anannular tangential burner through a primary air pneumatic conveying system and is sprayed into the combustion chamber through the burner in a gas-solid mixing mode, a man-made controllable, stable andefficient rotation airflow field is built, and the strong heat and mass transfer process occurs to the interior of the airflow field; secondary air enters the combustion chamber, the combustion process is enhanced, and carbon in pulverized coal and carbon residues in fly ash makes strong oxidization combustion reaction with oxygen in air; and the combustion chamber has very high cross section heat intensity and hearth temperature, the ash content is molten, and generated high-temperature smoke enters the downstream technology systems such as a smoke waste heat recovery technology system froma lower smoke outlet.

Description

technical field [0001] The invention relates to the technical field of combustion chambers, in particular to a cyclone airflow field combustion chamber. Background technique [0002] combustion chamber. Anthracite, lean coal, bituminous coal, lignite, gasifier fly ash, slag, and biomass are used as fuel for combustion, and the fuel solid reacts violently with air in the combustion chamber. The ash components are melted into liquid and discharged, used as raw materials for the production of other products, waste heat recovery from flue gas to produce steam or provide heat source, and an energy conversion device. The energy input to the combustion chamber includes chemical energy and electrical energy in the fuel, combustion The chamber outputs steam, high temperature water or organic heat carrier with certain heat energy. The original meaning of the combustion chamber refers to the water container heated on the fire. The combustion chamber refers to the place where fuel is ...
