What is the working principle of the oil-gas hot blast furnace throughout the analysis?

Fuel gas hot blast furnace can be fueled by coal, diesel, oil and gas, with clean hot air as the drying medium, no pollution
.

Fuel oil gas hot blast furnace has the advantages
of low energy consumption, high thermal efficiency and simple operation.

The machine is widely used in pharmaceutical, chemical, food, textile printing and dyeing, grain processing, wood processing, automobile and other industrial fields of various products drying, curing, heat setting and other operations
.

The following small series to briefly introduce to you what is the working principle of the fuel gas hot blast furnace? 1.
Indirect oil-gas hot blast furnace is mainly suitable for drying materials that are not allowed to be polluted, or applied to the drying
of heat-sensitive materials with low temperatures.

Such as: milk powder, pharmaceutical, synthetic resin, fine chemicals, etc
.

This kind of heating device is to use vapor, heat transfer oil, flue gas, etc.
as a carrier to heat the air
through various forms of heat exchangers.

The most essential problem with indirect hot blast furnaces is heat exchange
.

The larger the heat exchange area, the higher the heat conversion rate, the better the energy saving effect of the hot blast furnace, and the longer
the life of the furnace body and heat exchanger.

Conversely, the size of the heat exchange area can also be identified
from the flue gas temperature.

The lower the smoke temperature, the higher the heat conversion rate, and the larger
the heat exchange area.

2, direct high-purification fuel oil gas hot blast furnace is the use of fuel direct combustion, through the high purification treatment to form a hot air, and direct contact with the material heating drying or baking
.

The fuel consumption of this method is about half that of steam or other indirect heaters
.

Therefore, without affecting the quality of the drying product, it is completely possible to use direct high-purification hot air
.

Fuels are liquid fuels, such as diesel and heavy oil
.

Fuels are gaseous fuels such as gas, natural gas, and liquid gas
.

The high-temperature combustion gas obtained by the fuel after the combustion reaction is further in contact with the outside air, mixed to a certain temperature and directly enters the drying room or baking room, in contact with the dried material, heating, evaporating water, so as to obtain the drying product
.

In order to take advantage of the combustion reaction heat of these fuels, an additional fuel combustion device
must be installed.

Such as: fuel burner, etc
.
