Air Products offers a range of gasbased technologies and a full line of industrial gases, including oxygen and nitrogen to assist with your blast furnace operation. Oxygen can be injected into the blast furnace to improve combustion and facilitate the supplemental injection of pulverized coal or natural gas to reduce coke costs.
Oct 04, 2018· Coal explosibility affects the safety during the injection of coal in the BF. Reactivity – The reactivity of coal refers to reacting ability of coal with carbon dioxide (CO2) or water vapour (H2O) under certain conditions. After pulverized coal injection in the BFe, part of the unburned coal (char) reacts with CO2 while ascending with the gas.
examining the coinjection of pulverized coal and natural gas, using separate lances for each fuel. The natural gas enters through a simple pipe and the coal enters through an annular pipe in which the coal is conveyed through the centre and an annular flow of cooling air is either swirled or turned off. Mixing, combustion, and heat loads to the

Pulverized Coal Injection (PCI) using the denseflow method. The Küttner developed and perfected denseflow method offers several advantages over a lowerdensity system. Higher injection rates are achieved with simultaneously lower coke rates, which can optimize the fuel costs of the blast furnace. In addition, denseflow technology enables ...
Pulverized coal injection is a process that involves blowing large volumes of fine coal granules into the BF. The raw material is by washing and removing the vermiculite from coal to form clean coal, which is high quality. Pulverized coal: pulverized is a technology that is a reasonable choice for blast furnace technology advancement.
For maximum fuel efficiency and low emissions levels, you need a precise and consistent coal feed. The PFISTER® SCF delivers. Thanks to the integrated dosing electronics, this smart coal feeder provides highly accurate and reliable gravimetric feeding of pulverized fuels to the burning process, including coal dust, lignite dust and petcoke.

Coal injection system. Reduced pollution Coal grinding and injection systems are nonpolluting systems. Injecting pulverized coal into a blast furnace reduces the overall pollution made by coke production. Increased productivity Installation of a coal injection system can increase productivity through improved operation of the blast furnace.
A pulverized coalfired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.
Injecting pulverized coal and natural gas into blast furnaces for ironmaking decreases metallurgical coke requirements, providing a net decrease in the CO 2 emissions and in many cases, operating costs associated with iron production. Ideally, the fuel would enter the raceway partially reacted and the injection would not have negative impacts on the equipment or process.
