Embodiment Construction

[0008] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0009] Depend on Figure 1-2 As shown, the present invention includes a bell-shaped swirl and return combustion chamber 1, a circular porous heat storage cone 2, a gas inlet pipe 3, an air inlet pipe 4, an air inlet nozzle 6 and an air mixing loop 5 with an upper opening, The swirl and return combustion chamber 1 is an annular space formed between a bell-shaped wall 7 and a circular porous heat storage cone 2; the circular porous heat storage cone 2 is formed by stacking porous lattice bricks. The circular bottom of the swirl and recirculation combustion chamber begins to gradually narrow its diameter upwards. On the side of the bell-shaped wall 7, a gas inlet pipe 3 and an air inlet pipe 4 are arranged radially on the same horizontal plane, and the gas inlet pipe 3 and The air intake pipe 4 communicates with the swirl and retu...

Abstract

The invention relates to a burner with quick swirl mixing device for burning in porous cone, which can effectively solve the problems that most of furnace burning devices are complex and need large burning space, the gas is not mixed uniformly, the burning is incomplete, the environment is polluted and energy is wasted; the swirl and reflux burning chamber is an annular space between the bell-shaped wall and the round porous heat storage cone; the side of the bell-shaped wall is provided with a gas and air inlet tube; the gas and air inlet tube is connected with the swirl and reflux burning chamber by an air inlet nozzle; a flow guild baffle is disposed in the air inlet nozzle, the opening is faced to the airflow mixing annular channel, so as to solve the problems that the burning of the low-heat value gas is not stable, the burning intensity is small and the burning temperature is low; the invention can not only realize quick airflow mixing, high temperature pre-heating in the porous cone and high-intensity burning under the condition of simple structure, but also the invention plays a vital role in simplifying the whole structure of industrial furnace and improving the thermal performance.

Description

technical field [0001] The invention relates to a burner for burning in a porous cone with a rapid swirl mixing device for a blast furnace hot blast stove and other industrial kilns. Background technique [0002] At present, blast furnace hot blast stoves and other industrial furnaces are required to obtain high performance and high benefits under the combustion of low calorific value blast furnace gas from the perspective of energy saving and consumption reduction, and finally achieve the goals of high efficiency, energy saving, environmental protection, and increased production. For this reason, an efficient and enhanced combustion process is very necessary, which relates to the performance of the combustion device. Throughout the various gas combustion devices currently in use, they are mainly based on the mixing, preheating and ignition of gas and air in the combustion space. This mode always has uneven mixing, incomplete combustion, large combustion chamber space, The ...
