Indirect Fired Hot Air Generator

Indirect fired hot air generator is the thermal equipment integrating with burning, heat exchange, dust removal, circulating air, emissions and other functions. The energy is converted into fresh hot air in one-time. It is different from the traditional electric/coal fired hot air generator, which is not bulky, complicated structure, high cost and difficult to maintain. It is widely used in drying industry of 120℃ - 200℃ becaused of high efficiency energy saving.

Indirect fired Hot Air Generator


1. Product Introduction of the indirect hot air generator

Indirect hot air generator is manufactured for the hot air supply of industrial and agricultural drying plants. With the use of regionally available biomass instead of traditional fuels, the drying costs can be significantly reduced. Flexible technology and years of experience in the design of hot air systems allow the combination with almost all available dryer models. Customized production is more suitable for customers' needs. Full automatic feeding system can save labor cost for customers.

3. Product Feature of the biomass hot air generator

◆ Full intelligent control system, automatic feeding, automatic temperature control, automatic ignition, over temperature protection, fault alarm, convenient operation

◆ The furnace inside is made of 304 stainless steel 5mm thick profiles, and adopts the international top "multi-hearth, multi-return, full cold back" technology to improve efficiency.

◆ Using the technology of international top "multi-hearth and multi-return", the heat transfer area can be increased in large quantity, so that the heat can stay in the furnace for longer, so as to achieve full heat exchange.

◆ Built-in cyclone dust removal to achieve smokeless and dust-free emission.

◆ The boiler design has multi-layer safety protection device; Eliminate the phenomenon of detonation and tempering.

◆ Using the unique semi-gasification boiling combustion system, the ash content is 86% less than the traditional combustion method (direct combustion).
