How many temperatures can the biomass hot blast stove reach?

Before answering the question of how much temperature a biomass hot-blast stove can reach, we must first understand what a biomass hot-blast stove is. As the name implies, it refers to a hot-blast stove burning biomass fuel, but the types of biomass hot-blast stoves used in different industries are different. Generally speaking, it can be divided into two categories: clean hot air and mixed flue gas hot air. Biomass hot-blast stove is generally used in food drying industry, so we take pure heat exchange hot-blast stove with clean hot air as an example to answer how much temperature a biomass hot-blast stove can reach and whether it can replace coal-fired hot-blast stove.

The answer is yes about whether it can replace coal-fired hot blast stoves. Take the drying of rice, wheat and corn, which are closely related to our lives. In the past, coal-fired hot stoves were used for drying, and the hot air temperature was generally between 70- 120 degrees. According to the practical application, the outlet temperature of the hot blast stove is generally between 90- 150 degrees, which can meet the temperature required for drying. Knowing the temperature of the coal-fired hot-blast stove, let's analyze whether the biomass hot-blast stove can reach the required temperature for drying. Hot blast stoves burning coal and biomass pellet fuel only burn different fuels. The calorific value of coal is generally 5000 kcal/kg, and that of biomass wood pellet fuel is generally 4000 ~ 4500 kcal/kg. According to the calculation, we can know that the original burning coal is 1kg. About 1.3kg of biomass wood particles are needed to replace it. As long as there is enough biomass granular fuel to provide heat during combustion, the biomass hot-blast stove we designed can meet the temperature required by the original coal-fired hot-blast stove, which requires us to fully consider whether the output of the biomass hot-blast stove is sufficient when purchasing. If we buy biomass hot stoves from regular manufacturers, such as those certified by agricultural machinery, we can generally replace the original coal-fired hot stoves. According to industry experience, a 600,000-kcal hot blast stove can drive three 20-ton or two 30-ton rice and wheat dryers, and a 900,000-kcal hot blast stove can drive three 30-ton or four 20-ton rice and wheat dryers.

According to the above analysis, we can know the answer. Biomass hot stoves can reach the temperature generated by coal-fired hot stoves, generally 60 to 150 degrees, which can completely improve some coal-fired hot stoves. Of course, if the temperature is higher than 150 degrees under special requirements, it can be designed according to the actual situation, and you can trust me privately if necessary.
