A gas/oil-fired hot blast stove is a recommended machine for use in a wet fertilizer production line, where wet granulating is a process that uses liquid solutions and adhesives to bind different powder particles together. In the wet granulation process, a non-toxic and volatile granulation solution is needed to gather the powder particles. The binding of particles usually occurs through the boost action of the impeller and results in the enlargement of the particles. Note that granulation does not depend on any compression forces during particle formation.
Gas-oil Hot-air Stove is always working with the dryer machine in the fertilizer production line.
The Gas-oil Hot-air Stove uses the fuel to burn directly, forms hot blast through high purification treatment, and directly contacts the material for heating and drying or baking. It has become a replacement product of electric heat source and traditional steam power heat source in many industries.
The fuel consumption of Hot-air Stove is about half of using steam or other indirect heaters. Therefore, the direct high-purification hot air can be used without affecting the quality of the dried product.
Fuel can be divided into:
1Solid fuels, such as coal and coke.
② Liquid fuel, such as diesel, heavy oil, alcohol-based fuel
③Gas fuel, such as coal gas, natural gas, and liquid gas.
The hot air produced by the fuel combustion reaction contact with the outside air and mix to a certain temperature, and then comes into the drying machine directly, so the mixed hot air full contacts with the fertilizer granules to carry away the moisture. In order to utilize the combustion reaction heat, a whole set of fuel combustion equipment must be worked together, such as: coal burners, oil burners, gas burners, etc.
In the drying process and the wet granulation process, the hot air stove is necessary related equipment, which provides the necessary heat source for the drier system. The series of gas/oil hot air stove has the features of high temperature, low pressure, accurate temperature control and high utilization of heat energy. The air pre-heater is set up in the tail of large hot air stove to improve the efficiency of Hot-air Stove.The convective heating surface adopts a higher reasonable rate on the basis of rigorous calculation to ensure the full heat transfer of the furnace body and the high thermal efficiency of Gas-oil Hot-air Stove.
There are other machines in the fertilizer production line that we may not often mention, but sometimes they are also needed, such as: dehydrators, cyclone dust collectors, furnaces, etc., if you are not clear, you can consult at any time.
