Why is the efficiency of hot blast stove low?

There are several main aspects:

First, because of the design and manufacturing reasons, more attention is paid to the pressure-bearing parts and less to the combustion device in the design.

Second, because of the use of the pot, the capacity selected by the user of the hot blast stove does not match the actual use capacity.

Third, the coal used does not meet the design coal type of hot blast stove, and the coal quality indexes such as calorific value, volatile matter or particle size do not meet the design coal type requirements of hot blast stove. Fourth, the relevant systems and regulations such as energy-saving supervision of industrial hot-blast stoves are not perfect, and the technical standards are relatively backward.
