Hot air stove is a commonly used drying equipment, Hot Air Stove which is generally used for grain drying or wood drying treatment. It has obvious advantages in use, high efficiency, Hot Air Stove and good drying effect. However, the equipment needs to be maintained under long-term use to avoid slagging. In this regard, Hot Air Stove we will also analyze the causes and treatment methods of equipment slagging today. Slagging is due to the softened or melted ash particles not being sufficiently cooled at lower temperatures to meet the requirements of the cold water wall. When choosing a fuel, Hot Air Stove one should choose a fuel with low ash content, high ash melting point and stable combustion quality.
The unreasonable wind speed makes the flame in the furnace deviate to one side, Hot Air Stove causing the local temperature in the furnace to be too high. This causes the temperature of some fuel layers to rise to the ash melting point, Hot Air Stove and slagging is caused by the cooling delay. The high-load operation of the hot blast stove causes the furnace temperature to be too high, Hot Air Stove and the temperature of the fuel layer rises accordingly, Hot Air Stove reaching the ash melting point of the fuel, resulting in slagging.
Solution: Accurately judge the fuel performance, furnace size, heating surface layout, Hot Air Stove soot blowing system and ash removal device selection, regular dust removal, and recommend companies to use high calorific value, Hot Air Stove clean, easy to ignite biomass pellet fuel, when the hot blast stove is running, Pay attention to the situation in the furnace, Hot
Air Stove adjust the wind speed and air volume in time, improve the combustion quality, Hot Air Stove and ensure the full combustion and load requirements, adjust the temperature in the furnace, control the combustion in the furnace, Hot Air Stove and reduce the slagging to a lower level.
The above is an introduction to the cause analysis and treatment methods of slagging in hot blast furnace, Hot Air Stove I hope it will be helpful to you.
