Fuel oil hot air furnace classification, to output the air temperature is divided into: high temperature furnace, furnace heat exchange, to form is divided into: indirect oil-fired air heater and direct oil-fired air heater, the heat exchanger at the mercy of the form as one of oil-fired air heater and split fuel hot-blast stove.

Fuel oil, heavy oil, can be used: natural gas

A direct type, high purifying fuel hot-blast stove

Is the use of fuel direct combustion, high purification treatment to form hot air, hot air directly use. The method of fuel consumption than by steam or other indirect heater is reduced by a half. Therefore, without affecting the drying product quality situation, and can be used directly to high purify air.

Fuel can be used: diesel, heavy oil.

Two, indirect oil-fired air heater

Mainly applicable to dry material contamination is not permitted, or used in low temperature drying heat-sensitive materials. Such as: milk powder, pharmaceuticals, synthetic resin, fine chemicals.

Type blast furnace the most essential problem is the heat exchange. The heat exchange area is large, the heat conversion rate is high, the better the energy saving hot-blast stove, a stove body and a heat exchanger the longer life expectancy. Conversely, the heat exchange area size can also be identified from the flue gas temperature. The smoke temperature becomes lower, the heat transfer rate is high, the heat exchange area is bigger.
