Combustion system of heat storage type heating furnace

Abstract

The invention provides a combustion system of a heat storage type heating furnace. The combustion system comprises the heating furnace, heat storage boxes are arranged on the outer wall of the heating furnace, air faucets are arranged in the heating furnace, the air faucets are connected with the heat storage boxes through pipelines, flat flame fans are arranged right opposite to the air faucets and perpendicular to the air faucets, the air faucets and the flat flame fans are arranged in conical holes in the outer wall of the heating furnace, the number of the heat storage boxes is two, the two air faucets are arranged correspondingly, the working states of the two air faucets are different, namely, when one air faucet is in an air suction state, the other air faucet is in an air injection state, and the working states of the air faucets can be converted. The combustion system of the heat storage type heating furnace has the advantages that energy is saved, consumption is lowered, waste gas collection is facilitated, environment pollution is reduced, heat storage energy is more sufficient due to the fact that the two heat storage boxes are used for conducting heat storage processing for storing heat respectively, the working efficiency of the heat storage type heating furnace is improved and the heat storage type heating furnace is convenient to clean.

Description

technical field [0001] The invention relates to a combustion system of a heating furnace, in particular to a combustion system for a regenerative heating furnace. Background technique [0002] Industrial heating furnaces are usually heated by conventional oil and gas combustion. Since the heating furnace does not have a treatment device, it causes insufficient combustion, reduces production efficiency, and it is not easy to collect the flue gas after combustion, causing environmental pollution. Now there are also regenerative heating furnaces. Regenerative heating furnaces are a new type of heating furnaces used in rolling mills. They have the advantages of high-efficiency combustion, recycling flue gas and low carbon dioxide emissions. It is widely used in industrial enterprises and plays an important role in promoting energy conservation and emission reduction. However, the current regenerative heating furnace has only one regenerative tank, which easily causes gas mixin...

Problems solved by technology

At present, most of the flame nozzles of heating furnaces use nozzles to spray fire directly on the workpiece to be heated, which often causes uneven heating of the workpiece when heated; when oil and gas are used for heating, the flame temperature is relatively high, and the flame is sprayed directly on the workpiece, often Will cause damage to the workpiece, or fail to achieve the effect after the workpiece is heated

On the other hand, using a nozzle to spray fire directly on the workpiece consumes a lot of oil and gas, which increases the production cost of the enterprise
