The structure of hot blast furnace is composed of combustion furnace and advanced high-efficiency heat exchanger. The product structure of hot blast furnace is characterized by high temperature, high efficiency and low pollution combustion furnace, high thermal efficiency; the combustion mode of coal-fired hot blast furnace adopts the combination of mechanized chain grate and new energy-saving combustion arch, which can realize full combustion; high degree of mechanization, simple and convenient operation; new type of combustion arch is adopted The heat exchanger of type A is full of heat exchange, not easy to block and easy to clean; the upper part of the heat exchange tube of the hot blast furnace is made of stainless steel tube, which is not only resistant to high temperature scouring and has a long life, but also has a heat exchange process of 7.5 meters long and sufficient heat exchange; the combination of gravity settlement and multi tube cyclone dedusting is adopted to make the smoke emission meet the requirements of environmental protection.
In the heat exchange area of the hot blast stove, several heat conducting tubes are arranged in parallel with the furnace body to realize heat exchange, and the heat absorbing fins and heat radiating fins are respectively arranged inside and outside the heat conducting tubes. So we can see more advanced heat conduction technology, coal combustion technology and hot air flow technology
