Do you know the conditions of charcoal combustion in a hot blast stove?
The main fuel of coal-fired hot blast stoves is coal. If we want to enable coal to be fully combusted, we need to have some combustion conditions.
1. Sufficient oxygen
In order to make all the combustible components of coal burn, most of them will be converted into carbon dioxide, sulfur dioxide, water gas products, we must ensure sufficient air, if there is no oxygen, coal can not be burned, because we must ensure that the hot air stove The air supply in the air. Among the supporting facilities of the coal-fired hot blast stove, the turbofan only needs to meet this condition, and a large amount of air can be blown into the furnace to supply a large amount of oxygen to support the combustion of coal.
2. High temperature environment
High temperature can significantly improve the combustion of coal, and it is beneficial to accelerate the combustion reaction and the stability of fire, and reduce the loss of chemical and mechanical incomplete combustion. In addition, coal can burn only when it reaches the specified ignition point. The vault of the hot blast stove and the internal combustion chamber are designed around the principle of heat non-diffusion, and the closed structure of the hot blast stove is the guarantee of the high temperature environment!
Three, the combustion material and air are fully mixed
In order to ensure that the coal fuel and air can achieve sufficient mixing and maintain good contact with it, we can do this by reducing the particle size of coal, increasing the surface area of coal reaction, performing pressurized combustion, and adjusting the movement of airflow. The hot blast stove can be equipped with pulverized coal preparation equipment to put coal into the combustion chamber with smaller particles, and it can be fully burned in an instant, which is highly efficient and energy-saving!
