Product Details
1、 Overview of blast furnace gas: Blast furnace gas is a byproduct produced during the ironmaking process, mainly composed of CO, CO2, N2, H2, CH4, etc. The combustible component CO accounts for about 25%, while the content of H2 and CH4 is very low. The content of CO2 and N2 accounts for 15% and 55% respectively, with a calorific value of only 3500KJ/m ³ About 750-800 kcal/cubic meter.
2、 Characteristics of blast furnace gas:
(1) Blast furnace gas has a high non combustible content and a low combustible content (about 30%), low heating value, and is not easy to ignite.
(2) Blast furnace gas is a colorless, odorless, and odorless gas with high CO content, resulting in high toxicity;
(3) Slow combustion speed and longer flame;
(4) The blast furnace gas contains a large amount of dust and must be filtered;
(5) The safety specification is set at 1 meter; The CO content in the air should not exceed 30mg;
(6) The ignition temperature is greater than 700 ℃.
(7) Blast furnace gas contains H2 (1.5-3.0%), CH4 (0.2-0.5%), CO (25-30%), CO2 (9-12%), N2 (55-60%), and O2 (0.2-0.4%); The density is 1.29-1.30 Kg/Nm3.
3、 Blast furnace gas burners and industrial furnaces: Zhengzhou Zhongwei Environmental Protection Equipment Co., Ltd. is a manufacturer of thermal energy technology research and industrial furnace application. It has developed multiple domestic blast furnace gas burners and combustion control systems based on the characteristics of blast furnace gas, and is widely used in industrial furnaces and kilns, such as baking machines, forging heating furnaces, rolling heating furnaces, drying machines, rotary kilns, and other lime shaft kilns, Good economic and social benefits have been achieved.
