Abstract

The invention discloses combustion equipment. The combustion equipment is adapted to combust a gaseous fuel, and the gaseous fuel comprises a first portion of fuel and a second portion of the fuel. The combustion equipment comprises an air box, a primary combustion chamber, a secondary combustion chamber, an igniter and a combustion-stabilizing cone, wherein the primary combustion chamber is arranged in the air box, the primary combustion chamber is provided with a primary heat storage ring in a surrounding mode, the primary combustion chamber is suitable for combusting the first portion of fuel; the secondary combustion chamber is arranged in the air box and axially communicates with the primary combustion chamber, the secondary combustion chamber is provided with a secondary heat storagering in a surrounding mode, the secondary combustion chamber is suitable for combusting the second portion of fuel; the igniter extends into the primary combustion chamber, and is suitable for igniting the first portion of fuel in the primary combustion chamber; and the combustion-stabilizing cone is arranged in the primary combustion chamber, the combustion-stabilizing cone is suitable for diffusing the fuel gas of the primary combustion chamber so as to ignite the second portion of fuel in the secondary combustion chamber. According to the combustion equipment, ignition of the gas fuel canbe ensured, and combustion can be fully and stably carried out.

Description

technical field [0001] The invention relates to the technical field of gas fuel combustion, in particular to a combustion device. Background technique [0002] In the industrial equipment of iron and steel, metallurgy and coal chemical industry, a large amount of gaseous fuels with low calorific value such as blast furnace gas, converter gas, water gas and producer gas are usually produced. These gaseous fuels need to be further burned before they can be denitrified in the SCR equipment. However, the calorific value of the above-mentioned gas fuel is very low, only 3.0-10.0MJ / m3. If the gas fuel burns unstable and fires are frequently extinguished, accidents such as deflagration and explosion will easily occur after the gas gathers. [0003] In the prior art, high-calorific-value fuels are commonly used to combust gaseous fuels with low calorific value. For example, liquefied petroleum gas, natural gas and other high-calorific fuels are used to ignite and support combustion...
