We manufacture horizontal type hot air generator, which finds standard use in industries such as tea, minerals, chemicals and fertilizers. This equipment has a total of three chambers viz combustion, mixing and outlet. The burner wall is present in the combustion chamber which has circular shape. This inner shell of this chamber is completely lined with a refractory material. In all, there are two concentric shells that have a gap between them. It is this gap that the dilution air is forced. The hot air generator also have an efficient burner, which increases its overall efficiency.
