Our product offerings include generators and hot air generator. We follow a stringent quality control norm throughout the process of production and every individual product is verified by our quality controllers before the final dispatch to the clients.
Direct Fired Hot Air Generator
 
Direct Fired Hot Air Generator
The (FBC) Fluidized Bed Combustion fired HAG system consists of a fluidized bed furnace, settling chamber and high efficiency cyclones. Hot air with minor dust particles having size lower than 20 microns from our hot air generator, enters the process.The total system is automated.
 

FBC Furnace With Wind Box:

Agro waste/Coal/Lignite fired FBC system comprising of a Nozzle plate with attached Air Plenum, a side structure frame bolted with Nozzle plate. Graded cast iron Nozzles fitted on top of the Nozzle plate and Sand drain pockets are provided for the removal of heavy unwanted silica particles.

 

Fuel Feeding With Screw Conveyor System:

M.S. Fabricated Fuel feeding venturi system is provided for feeding the fuel inside the furnace through S.F.D. Fan air.

 

Refractory Material:

All the standard / special shaped refractory bricks for furnace walls along with fixtures and holders are provided. The required Insulation bricks Mortar cements will be provided by us(for Furnace area Refractory work only).

 

Instrumentation And Safety Interlocks:

The system offered is extremely simple and convenient to operate. Alarms and safety interlocks have been provided to ensure correct working of the HAG. The following are a few of the safety inter locks.

  • Unless process suction fan is switched on, F.D.Fan / S.F.D.Fan / Fuel Feeders will not operate.
  • In case of high hot air temperature, audio/visual alarms are activated on the panel.
  • In case of high bed temperature audio/visual alarms are activated on the panel and fuel feeder speed is lowered down to minimum.
 

Control Panel:

The panel is PLC based, having sophisticated but user friendly controls enabling the operator to run the HAG in automatic or manual mode as desired. The control panel consists of main MCCB, inverters for fans and feeders with individual MCBs, annunciation module with hooter, PID controllers, indicating lamps and one auxiliary cont act.

Indirect Fired Hot Air Generator
The (FBC) Fluidized Bed Combustion fired HAG system consists of a Fluidized Bed Combustion Furnace, Radiative Heat Exchanger, Convective Heat Exchanger, Heat Recovery Unit, Air pollution control equipment as well as Inverter controlled fans.
Indirect Fired Hot Air Generator

Radiative Heat Exchanger:

Radiative Heat Exchanger comprises of a bank of S.S. Pipes, welded with a free floating Box Header, which rested on rollers, supported on a channel frame.

Convective Heat Exchanger:

Convective Heat Exchanger comprises of a bank of S.S./M.S Pipes, welded with a free floating Box Header rested on rollers, supported on a channel frame. These heat exchangers are in two stages, for increasing the overall system efficiency.

Heat Recovery Unit (HRU):

It recovers heat from the flue gases, and in turn heats the incoming clean atmospheric air by cross flow design.

Pollution Control Equipment:

High efficiency Cyclone is provided for collecting fine ash from flue gases emitted in the ambient through the stack.

FBC Furnace With Wind Box:

Groundnut shell/Coal/Lignite fired FBC system comprises of a Nozzle plate with attached Air Plenum and a side structure frame bolted with Nozzle plate . Graded CI (Cast iron) nozzles are fitted on top of the nozzle plate. Sand drain pockets are provided for removal of heavy unwanted silica particles from the FBC Furnace.

Refractory Material:

All the standard / specially shaped refractory bricks for the furnace walls along with fixtures and holders are provided. The required Insulation bricks, mortar cements are provided by us. (For Furnace / Heat Exchanger area Refractory work.

Instrumentation And Safety Interlocks:

The system offered is extremely simple and convenient to operate. Alarms and safety interlocks have been provided to ensure correct working of the HAG. The following are few of the safety inter locks.

  • Unless C.A. Fan is switched on, the I.D.Fan / F.D.Fan / S.F.D.Fan / Fuel feeders will not operate.
  • In case of high hot air temperature audio/visual alarms are activated on the panel.
  • In case of high bed temperature audio/visual alarms are activated on the panel and fuel feeder speed is lowered down to minimum.

Hot Air Generator
Hot Air Generator
  The HAG Series Hot Air Generator are offered in vertical or horizontal designs, either as standard models or tailor-made models to match customer's specifications and applications. Designed in direct and indirect heating types, these systems are practically free from any maintenance and are highly efficient. Direct systems find their applications in high temperature drying, whereas the Indirect systems are used where pure air is required for drying. The design is compact & hence space saving. Units are designed for continuous round the clock operation.
  Salient features of the RG series hot air generators are:

  • Durable construction
  • Easy operation and minimal maintenance
  • High level of safety in operation, thus greater reliability
  • Optional recirculation system to improve overall thermal efficiency
  • Fully automatic burner control and temperature control
  • Units are available from capacities of 20,000 Kcal/hr to 30,00,000
